Unsigned SAML LogoutRequest Acceptance in gosaml2

Summary The ValidateEncodedLogoutRequestPOST function in gosaml2 accepts completely unsigned SAML LogoutRequest messages even when SkipSignatureValidation is set to false. When validateElementSignature returns dsig.ErrMissingSignature, the code in decodelogoutrequest.go:60-62 silently falls throu...

CVE-2025-59934

Formbricks (pre-4.0.1) is affected by missing JWT signature verification. A token validation path uses jwt.decode without signature checks, allowing an attacker who knows a user’s user.id to craft a JWT with alg: none and authenticate or reset the victim’s password. The same validator is used for...

Linux Distros Unpatched Vulnerability : CVE-2017-16852

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - shibsp/metadata/DynamicMetadataProvider.cpp in the Dynamic MetadataProvider plugin in Shibboleth Service Provider before 2.6.1 fails to properly configure itsel...

CVE-2024-48916: Insufficient Verification of Data Authenticity

Ceph is a distributed object, block, and file storage platform. In versions 19.2.3 and below, it is possible to send an JWT that has "none" as JWT alg. And by doing so the JWT signature is not checked. The vulnerability is most likely in the RadosGW OIDC provider. As of time of publication, a kno...

CVE-2024-42459

A flaw was found in the NodeJS Elliptic package. When creating EDDSA signatures, the Elliptic package doesn't properly check the signature length, allowing zeros to be added or removed from the signature without invalidating it, which may result in confidentiality issues. Mitigation Mitigation fo...
