JLSEC-2026-108 Deno's AES GCM authentication tags are not verified

Summary This affects AES-256-GCM and AES-128-GCM in Deno, introduced by commit 0d1beed. Specifically, the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno...

CVE-2026-5500 Improper Validation of AES-GCM Authentication Tag Length in PKCS#7 Envelope Allows Authentication Bypass

wolfSSL's wcPKCS7DecodeAuthEnvelopedData does not properly sanitize the AES-GCM authentication tag length received and has no lower bounds check. A man-in-the-middle can therefore truncate the mac field from 16 bytes to 1 byte, reducing the tag check from 2⁻¹²⁸ to 2⁻⁸...

CVE-2026-32600

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,...

Improper Validation of Integrity Check Value

Overview robrichards/xmlseclibs is a PHP library for XML Security. Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in the decryptSymmetric function, when checking tag length for the aes-128-gcm, aes-192-gcm, and aes-256-gcm encryption algorithms. A...

GHSA-R353-4845-PR5P simplesamlphp/xml-security: Missing AES-GCM Authentication Tag Validation on Encrypted Nodes Allows for Unauthorized Decryption

Summary 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...

CVE-2026-32600

XML-Security library (xml-security) is affected in versions prior to 2.3.1 and 1.13.9 where AES-GCM encrypted XML nodes do not validate the authentication tag length. This can allow an attacker to brute-force the authentication tag, recover the GHASH key, decrypt encrypted nodes, and forge cipher...
