CVE ID :CVE-2026-32600
Published : March 13, 2026, 7:58 p.m. | 30 minutes ago
Description :xml-security is a library that implements XML signatures and encryption. Prior to 2.3.1, 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.
Severity: 0.0 | NA
