CVE-2024-54150 2026-04-15 9.1 Critical
cjwt is a C JSON Web Token (JWT) Implementation. Algorithm confusion occurs when a system improperly verifies the type of signature used, allowing attackers to exploit the lack of distinction between signing methods. If the system doesn't differentiate between an HMAC signed token and an RS/EC/PS signed token during verification, it becomes vulnerable to this kind of attack. For instance, an attacker could craft a token with the alg field set to "HS256" while the server expects an asymmetric algorithm like "RS256". The server might mistakenly use the wrong verification method, such as using a public key as the HMAC secret, leading to unauthorised access. For RSA, the key can be computed from a few signatures. For Elliptic Curve (EC), two potential keys can be recovered from one signature. This can be used to bypass the signature mechanism if an application relies on asymmetrically signed tokens. This issue has been addressed in version 2.3.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2025-58356 1 Edgelesssys 1 Constellation 2026-04-15 N/A
Constellation is the first Confidential Kubernetes. The Constellation CVM image uses LUKS2-encrypted volumes for persistent storage. When opening an encrypted storage device, the CVM uses the libcryptsetup function crypt_activate_by_passhrase. If the VM is successful in opening the partition with the disk encryption key, it treats the volume as confidential. However, due to the unsafe handling of null keyslot algorithms in the cryptsetup 2.8.1, it is possible that the opened volume is not encrypted at all. Cryptsetup prior to version 2.8.1 does not report an error when processing LUKS2-formatted disks that use the cipher_null-ecb algorithm in the keyslot encryption field. This vulnerability is fixed in 2.24.0.
CVE-2025-59934 1 Formbricks 1 Formbricks 2026-04-15 9.4 Critical
Formbricks is an open source qualtrics alternative. Prior to version 4.0.1, Formbricks is missing JWT signature verification. This vulnerability stems from a token validation routine that only decodes JWTs (jwt.decode) without verifying their signatures. Both the email verification token login path and the password reset server action use the same validator, which does not check the token’s signature, expiration, issuer, or audience. If an attacker learns the victim’s actual user.id, they can craft an arbitrary JWT with an alg: "none" header and use it to authenticate and reset the victim’s password. This issue has been patched in version 4.0.1.
CVE-2025-27813 2026-04-15 8.1 High
MSI Center before 2.0.52.0 has Missing PE Signature Validation.
CVE-2020-36843 2026-04-15 4.3 Medium
The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks) property. This allows attackers to create new valid signatures different from previous signatures for a known message.

Improper signature verification in AMD CPU ROM microcode patch loader may allow an attacker with local administrator privilege to load malicious microcode, potentially resulting in loss of integrity of x86 instruction execution, loss of confidentiality and integrity of data in x86 CPU privileged context and compromise of SMM execution environment.
CVE-2025-32060 1 Bosch 1 Infotainment System Ecu 2026-04-15 6.7 Medium
The system suffers from the absence of a kernel module signature verification. If an attacker can execute commands on behalf of root user (due to additional vulnerabilities), then he/she is also able to load custom kernel modules to the kernel space and execute code in the kernel context. Such a flaw can lead to taking control over the entire system. First identified on Nissan Leaf ZE1 manufactured in 2020.
CVE-2025-32977 1 Quest 1 Kace Systems Management Appliance 2026-04-15 9.6 Critical
Quest KACE Systems Management Appliance (SMA) 13.0.x before 13.0.385, 13.1.x before 13.1.81, 13.2.x before 13.2.183, 14.0.x before 14.0.341 (Patch 5), and 14.1.x before 14.1.101 (Patch 4) allows unauthenticated users to upload backup files to the system. While signature validation is implemented, weaknesses in the validation process can be exploited to upload malicious backup content that could compromise system integrity.
CVE-2025-54419 1 Node-saml 1 Node-saml 2026-04-15 10 Critical
A SAML library not dependent on any frameworks that runs in Node. In version 5.0.1, Node-SAML loads the assertion from the (unsigned) original response document. This is different than the parts that are verified when checking signature. This allows an attacker to modify authentication details within a valid SAML assertion. For example, in one attack it is possible to remove any character from the SAML assertion username. To conduct the attack an attacker would need a validly signed document from the identity provider (IdP). This is fixed in version 5.1.0.
CVE-2024-11957 1 Kingsoft 1 Wps Office 2026-04-15 N/A
Improper verification of the digital signature in ksojscore.dll in Kingsoft WPS Office in versions equal or less than 12.1.0.18276 on Windows allows an attacker to load an arbitrary Windows library. The patch released in version 12.2.0.16909 to mitigate CVE-2024-7262 was not restrictive enough.
CVE-2025-55278 1 Hcltech 1 Devops Loop 2026-04-15 8.1 High
Improper authentication in the API authentication middleware of HCL DevOps Loop allows authentication tokens to be accepted without proper validation of their expiration and cryptographic signature. As a result, an attacker could potentially use expired or tampered tokens to gain unauthorized access to sensitive resources and perform actions with elevated privileges.
CVE-2024-54126 1 Tp-link 1 Archer C50 Firmware 2026-04-15 N/A
This vulnerability exists in the TP-Link Archer C50 due to improper signature verification mechanism in the firmware upgrade process at its web interface. An attacker with administrative privileges within the router’s Wi-Fi range could exploit this vulnerability by uploading and executing malicious firmware which could lead to complete compromise of the targeted device.
CVE-2026-33895 1 Digitalbazaar 1 Forge 2026-04-14 7.5 High
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, Ed25519 signature verification accepts forged non-canonical signatures where the scalar S is not reduced modulo the group order (`S >= L`). A valid signature and its `S + L` variant both verify in forge, while Node.js `crypto.verify` (OpenSSL-backed) rejects the `S + L` variant, as defined by the specification. This class of signature malleability has been exploited in practice to bypass authentication and authorization logic (see CVE-2026-25793, CVE-2022-35961). Applications relying on signature uniqueness (i.e., dedup by signature bytes, replay tracking, signed-object canonicalization checks) may be bypassed. Version 1.4.0 patches the issue.
CVE-2026-32883 2 Botan Project, Randombit 2 Botan, Botan 2026-04-14 5.9 Medium
Botan is a C++ cryptography library. From version 3.0.0 to before version 3.11.0, during X509 path validation, OCSP responses were checked for an appropriate status code, but critically omitted verifying the signature of the OCSP response itself. This issue has been patched in version 3.11.0.
CVE-2026-34840 2 Hackerbay, Oneuptime 2 Oneuptime, Oneuptime 2026-04-14 8.1 High
OneUptime is an open-source monitoring and observability platform. Prior to version 10.0.42, OneUptime's SAML SSO implementation (App/FeatureSet/Identity/Utils/SSO.ts) has decoupled signature verification and identity extraction. isSignatureValid() verifies the first <Signature> element in the XML DOM using xml-crypto, while getEmail() always reads from assertion[0] via xml2js. An attacker can prepend an unsigned assertion containing an arbitrary identity before a legitimately signed assertion, resulting in authentication bypass. This issue has been patched in version 10.0.42.
