CVE-2017-7822 : The AES-GCM implementation in WebCrypto API accepts a 0-length IV, contrary to NIST SP 800-38D’s 1-byte minimum, potentially enabling leakage of the authentication key in some cases. Affected software is Firefox

Authentication Bypass

json-jwt is vulnerable to authentication bypasses. The library does not properly validate the GCM auth tag length, allowing a malicious user to require at most 256 attempts to forge a valid auth tag...

Auth tag forgery vulnerability with AES-GCM encrypted JWT

Ruby's OpenSSL bindings do not check the length of the supplied authentication tag when decrypting an authenticated encryption mode such as AES-GCM, leaving this up to the authors of a gem/app to implement for properly validating the message. json-jwt was not checking for the authentication tag...
