CVE-2026-32313

xmlseclibs is a library written in PHP for working with XML Encryption and Signatures. Prior to 3.1.5, XML nodes encrypted with either aes-128-gcm, aes-192-gcm, or aes-256-gcm lack validation of the authentication tag length. An attacker can use this to brute-force an authentication tag, recover...

CVE-2026-32600

A flaw was found in xml-security, a library for XML signatures and encryption. This vulnerability arises from a lack of validation for the authentication tag length in XML nodes encrypted with AES-GCM Advanced Encryption Standard Galois/Counter Mode. A remote attacker can exploit this by...

SUSE CVE-2025-54887

jwe is a Ruby implementation of the RFC 7516 JSON Web Encryption JWE standard. In versions 1.1.0 and below, authentication tags of encrypted JWEs can be brute forced, which may result in loss of confidentiality for those JWEs and provide ways to craft arbitrary JWEs. This puts users at risk becau...
