SCA: security update for simplesamlphp/xml-security (GHSA-r353-4845-pr5p)

high Tenable Self-Hosted Container Security Plugin ID 438782

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - xml-security is a library that implements XML signatures and encryption. Prior to versions 2.3.1 and
 1.13.9, 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 the
 GHASH key, and decrypt the encrypted nodes. It also allows to forge arbitrary ciphertexts without knowing
 the encryption key. This vulnerability is fixed in 2.3.1 and 1.13.9. (CVE-2026-32600)

Solution

Update the simplesamlphp/xml-security library and its related packages to version 1.13.9 or later.
