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...

Xmlseclibs 安全漏洞

Xmlseclibs is a library developed by robrichards, written in PHP, for handling XML encryption and signing. Versions of Xmlseclibs prior to 3.1.5 contained security vulnerabilities. These vulnerabilities stemmed from the lack of authentication tag length validation for XML nodes encrypted using...

Authentication Bypass

robrichards/xmlseclibs is vulnerable to authentication bypass. The vulnerability is due to improper handling in the libxml2 canonicalization process where invalid XML inputs may return an empty string, which allows an attacker to bypass authentication by manipulating the DigestValue computation...

CVE-2025-66578

xmlseclibs is a library written in PHP for working with XML Encryption and Signatures. Versions 3.1.3 contain an authentication bypass vulnerability due to a flaw in the libxml2 canonicalization process during document transformation. When libxml2’s canonicalization is invoked on an invalid XML...
