CVE-2026-64370 1 Linux 1 Linux Kernel 2026-09-08 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Fix pid refcount leak in do_cpu_nanosleep() error path In do_cpu_nanosleep(), posix_cpu_timer_create() takes a pid reference via get_pid() and stores it in timer.it.cpu.pid. If the subsequent posix_cpu_timer_set() call fails, the function returns immediately without calling posix_cpu_timer_del() to release the pid reference, causing a leak. Fix it by calling posix_cpu_timer_del() before the unlock-and-return on the error path, consistent with the other exit paths in the same function.
CVE-2026-86419 1 Misp 1 Misp 2026-09-08 N/A
Affected versions of MISP contain insufficient validation of server-side outbound HTTP destinations in feed retrieval and TAXII discovery functionality. In feed processing, redirects were followed without validating the redirect scheme or destination. The original request headers were reused across redirect hops, meaning authentication headers or API credentials configured for a feed could be forwarded to a different host. Redirects could also target internal network resources, resulting in SSRF. The fix adds redirect validation, blocks internal destinations for cross-host redirects, strips configured feed credentials before following redirects to another host, and pins validated DNS results to prevent re-resolution after validation. The TAXII discovery endpoint had a related incomplete SSRF defense. It used gethostbyname() and compared the result against only a few literal addresses. This missed cases including IPv6 loopback (::1), numeric host encodings such as 0x7f000001, and potentially multiple DNS records. The fix moves TAXII discovery to the shared URL egress validator. Together, these commits harden MISP's outbound URL handling against alternate-address representations, DNS-related bypasses, unsafe redirects, internal-host access, and cross-host credential forwarding. Version affected: ≤2.5.45
CVE-2026-82757 1 Ash-project 1 Ash Authentication Oauth2 Server 2026-09-08 N/A
Server-Side Request Forgery (SSRF) vulnerability in ash-project ash_authentication_oauth2_server allows an attacker who controls a client metadata URL and its DNS to make the server connect to internal or loopback addresses. public_ip?/1 in AshAuthentication.Oauth2Server.CIMD.ReqFetcher enforces the outbound policy for CIMD metadata fetches. It classified several address forms as publicly routable that are not: IPv4-compatible ::/96 (for example ::127.0.0.1), SIIT IPv4-translated ::ffff:0:0:0/96, and deprecated site-local fec0::/10. A returned AAAA record in one of these ranges passed the policy, so a fetch pinned to that address reached space the policy was meant to block. This issue affects ash_authentication_oauth2_server: from 0.3.0 before 0.3.1.
CVE-2026-71626 1 Invoiceninja 1 Invoice Ninja 2026-09-08 7.5 High
An issue in Invoice Ninja v5.13.24 allows a remote attacker to obtain sensitive information via the StoreWebhookRequest.php, UpdateWebhookRequest.php, and WebhookSingle.php components
CVE-2026-73315 1 Xenforo 1 Xenforo 2026-09-08 8.6 High
XenForo before 2.3.13 contains a server-side request forgery vulnerability in the PayPal REST webhook handler that allows unauthenticated attackers to cause the server to make outbound HTTP requests to arbitrary destinations by supplying a crafted certificate URL in webhook headers without scheme, hostname, or allowlist validation. Attackers can submit a crafted POST to the PayPal webhook callback endpoint to reach internal network resources including cloud instance metadata services, potentially disclosing IAM credentials or enabling secondary internal service exploitation.
CVE-2026-86735 1 Snipeitapp 1 Snipe-it 2026-09-08 5 Medium
snipe-it versions before 8.7.0 contain a server-side request forgery vulnerability in the ExternalUrl validation rule that fails to detect IPv6 transition addresses encoding private IPv4 targets. Attackers with super-admin privileges can configure webhook URLs using NAT64, 6to4, or Teredo transition addresses to bypass SSRF guards and access internal services or cloud metadata endpoints.
CVE-2026-64376 1 Linux 1 Linux Kernel 2026-09-08 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: firmware_loader: fix device reference leak in firmware_upload_register() firmware_upload_register() -> fw_create_instance() -> device_initialize() After fw_create_instance() succeeds, the lifetime of the embedded struct device is expected to be managed through the device core reference counting, since fw_create_instance() has already called device_initialize(). In firmware_upload_register(), if alloc_lookup_fw_priv() fails after fw_create_instance() succeeds, the code reaches free_fw_sysfs and frees fw_sysfs directly instead of releasing the device reference with put_device(). This may leave the reference count of the embedded struct device unbalanced, resulting in a refcount leak. The issue was identified by a static analysis tool I developed and confirmed by manual review. Fix this by using put_device(fw_dev) in the failure path and letting fw_dev_release() handle the final cleanup, instead of freeing the instance directly from the error path.
CVE-2026-86259 1 Thu-maic 1 Openmaic 2026-09-08 7.5 High
OpenMAIC before 1.0.1 skips server-side request forgery validation in non-production builds, allowing unauthenticated attackers to reach cloud instance metadata services. Attackers can supply arbitrary provider URLs via the x-base-url header or baseUrl parameter to access sensitive cloud credentials and metadata.
CVE-2026-86240 2 Feehi, Liufee 2 Feehicms, Feehicms 2026-09-08 4.7 Medium
A security flaw has been discovered in liufee FeehiCMS up to 2.1.1. This affects the function catchImage of the file backend/widgets/ueditor/Uploader.php of the component UEditor. The manipulation of the argument source[] results in server-side request forgery. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-52769 1 Yeswiki 1 Yeswiki 2026-09-08 8.3 High
YesWiki is a wiki system written in PHP. From version 4.6.2 to before version 4.6.6, the POST /api/forms/{formId}/actor/inbox route - exposed publicly with acl:"public" - accepts an HTTP Signature header whose keyId parameter is a URL. HttpSignatureService::verifySignature() parses the header and immediately makes a server-side HTTP GET to that URL, before any cryptographic verification or URL validation. An unauthenticated remote attacker can therefore make YesWiki issue arbitrary outbound HTTP requests to any host the server can reach - internal services, cloud-metadata endpoints (169.254.169.254), intranet-only admin panels, etc. - and read enough back via timing and error-message oracles to scan ports, enumerate services, and (on a real cloud instance) reach IAM metadata. The only deployment-side precondition is that ActivityPub be enabled on at least one Bazar form. This issue has been patched in version 4.6.6.
CVE-2026-86590 1 Eclipse 1 Che 2026-09-08 N/A
In Eclipse Che versions 7.79.0 through 7.121.0, the dashboard backend's POST /dashboard/api/data/resolver endpoint passes a caller-supplied URL directly to an outbound HTTP GET request with no host filtering. An authenticated user can exploit this server-side request forgery (SSRF) to read responses from internal network addresses, including the cloud instance metadata service (169.254.169.254), loopback interfaces, RFC-1918 private ranges, and in-cluster Kubernetes services. The operator-configured allowlist (spec.devEnvironments.allowedSources.urls) is not consulted. The vulnerability is fixed in version 7.122.0, which adds private-address blocking, IPv4-mapped IPv6 bypass prevention, operator allowlist enforcement, and disables HTTP redirects on the outbound request.
CVE-2026-86321 1 Java-json-tools 1 Jackson-coreutils 2026-09-08 5.3 Medium
A vulnerability was found in java-json-tools jackson-coreutils 2.0. Affected by this issue is the function JsonLoader.fromURL of the file src/main/java/com/github/fge/jackson/JsonLoader.java of the component URL Validation. The manipulation results in server-side request forgery. It is possible to launch the attack remotely. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-76851 1 Github 1 Enterprise Server 2026-09-08 8.8 High
A Server-Side Request Forgery (SSRF) vulnerability was identified in GitHub Enterprise Server that allowed remote code execution on the instance. Insufficient network isolation allowed malicious pre-receive hook code to impersonate an internal service and redirect trusted internal requests to a privileged service, leading to elevated code execution. Exploitation required pre-receive hook networking to be enabled and either site administrator privileges or write access to a repository containing a configured pre-receive hook. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.22 and was fixed in versions 3.17.20, 3.18.14, 3.19.11, 3.20.7, and 3.21.5. This vulnerability was reported via the GitHub Bug Bounty program.
CVE-2026-86503 1 Jetbrains 1 Intellij Idea 2026-09-08 3.3 Low
In JetBrains IntelliJ IDEA before 2026.2.2 opening an untrusted project could trigger SSRF via Kubernetes spec-source URL fetching
CVE-2026-81806 2 John Darrel, Wordpress 2 Hide My Wp Ghost, Wordpress 2026-09-08 7.2 High
Server-Side Request Forgery (SSRF) vulnerability in John Darrel Hide My WP Ghost allows Server Side Request Forgery. This issue affects Hide My WP Ghost: from n/a through 7.0.09.
CVE-2026-76971 2026-09-08 6.5 Medium
Due to a Server-Side Request Forgery (SSRF) vulnerability in SAP Manufacturing Integration and Intelligence, an attacker could cause the server to initiate arbitrary outbound requests. If processed by the application, this behavior could be combined with XML/XSL processing to enable execution of scripts. Successful exploitation could result in a low impact on the confidentiality, integrity, and availability of the application.
CVE-2026-52943 1 Linux 1 Linux Kernel 2026-09-08 7.8 High
In the Linux kernel, the following vulnerability has been resolved: net: skbuff: fix missing zerocopy reference in pskb_carve helpers pskb_carve_inside_header() and pskb_carve_inside_nonlinear() both copy the old skb_shared_info header into a new buffer via memcpy(), which includes the destructor_arg pointer (uarg) for MSG_ZEROCOPY skbs. Neither function calls net_zcopy_get() for the new shinfo, creating an unaccounted holder: every skb_shared_info with destructor_arg set will call skb_zcopy_clear() once when freed, but the corresponding net_zcopy_get() was never called for the new copy. Repeated calls drive uarg->refcnt to zero prematurely, freeing ubuf_info_msgzc while TX skbs still hold live destructor_arg pointers. KASAN reports use-after-free on a freed ubuf_info_msgzc: BUG: KASAN: slab-use-after-free in skb_release_data+0x77b/0x810 Read of size 8 at addr ffff88801574d3e8 by task poc/220 Call Trace: skb_release_data+0x77b/0x810 kfree_skb_list_reason+0x13e/0x610 skb_release_data+0x4cd/0x810 sk_skb_reason_drop+0xf3/0x340 skb_queue_purge_reason+0x282/0x440 rds_tcp_inc_free+0x1e/0x30 rds_recvmsg+0x354/0x1780 __sys_recvmsg+0xdf/0x180 Allocated by task 219: msg_zerocopy_realloc+0x157/0x7b0 tcp_sendmsg_locked+0x2892/0x3ba0 Freed by task 219: ip_recv_error+0x74a/0xb10 tcp_recvmsg+0x475/0x530 The skb consuming the late access still referenced the same uarg via shinfo->destructor_arg copied by pskb_carve_inside_nonlinear() without a refcount bump. This has been verified to be reliably exploitable: a working proof-of-concept achieves full root privilege escalation from an unprivileged local user on a default kernel configuration. The fix follows the pattern of pskb_expand_head() which has the same memcpy/cloned structure. For pskb_carve_inside_header(), net_zcopy_get() is placed after skb_orphan_frags() succeeds, so the orphan error path needs no cleanup. For pskb_carve_inside_nonlinear(), net_zcopy_get() is placed after all failure points and just before skb_release_data(), so no error path needs cleanup at all -- matching pskb_expand_head() more closely and avoiding the need for a balancing net_zcopy_put().
CVE-2026-52912 1 Linux 1 Linux Kernel 2026-09-08 7.8 High
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_queue: hold bridge skb->dev while queued br_pass_frame_up() rewrites skb->dev from the ingress port to the bridge master before queueing bridge LOCAL_IN packets. NFQUEUE only holds references on state.in/out and bridge physdevs, so a queued bridge packet can retain a freed bridge master in skb->dev until reinjection. When the verdict is reinjected later, br_netif_receive_skb() re-enters the receive path with skb->dev still pointing at the freed bridge master, triggering a use-after-free. Store skb->dev in the queue entry, hold a reference on it for the queue lifetime, and use the saved device when dropping queued packets during NETDEV_DOWN handling.
CVE-2026-46046 1 Linux 1 Linux Kernel 2026-09-08 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ext4: fix missing brelse() in ext4_xattr_inode_dec_ref_all() The commit c8e008b60492 ("ext4: ignore xattrs past end") introduced a refcount leak in when block_csum is false. ext4_xattr_inode_dec_ref_all() calls ext4_get_inode_loc() to get iloc.bh, but never releases it with brelse().
CVE-2026-46040 1 Linux 1 Linux Kernel 2026-09-08 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: inotify: fix watch count leak when fsnotify_add_inode_mark_locked() fails When fsnotify_add_inode_mark_locked() fails in inotify_new_watch(), the error path calls inotify_remove_from_idr() but does not call dec_inotify_watches() to undo the preceding inc_inotify_watches(). This leaks a watch count, and repeated failures can exhaust the max_user_watches limit with -ENOSPC even when no watches are active. Prior to commit 1cce1eea0aff ("inotify: Convert to using per-namespace limits"), the watch count was incremented after fsnotify_add_mark_locked() succeeded, so this path was not affected. The conversion moved inc_inotify_watches() before the mark insertion without adding the corresponding rollback. Add the missing dec_inotify_watches() call in the error path.
