CVE-2026-84483 WWBN AVideo Unauthenticated Password Hash Oracle via encryptPass.json.php
WWBN AVideo through commit 9c39d8c8 contains an incomplete authentication bypass in encryptPass.json.php that allows unauthenticated attackers to compute valid HMAC tokens using the public site URL and current time. Attackers can forge authentication tokens by computing hashhmac with the site's...
CVE-2026-84483
WWBN AVideo through commit 9c39d8c8 contains an incomplete authentication bypass in encryptPass.json.php . An unauthenticated attacker can forge valid HMAC tokens by computing hash_hmac with the site's public base URL as the key and the current time as the message. With forged tokens, an attacker...

Name of the Vulnerable Software and Affected Versions WWBN AVideo versions prior to commit 9c39d8c8 Description An incomplete authentication bypass exists in the 'encryptPass.json.php' endpoint. This flaw allows unauthenticated attackers to compute valid HMAC Hash-based Message Authentication Cod...
Improper Verification of Cryptographic Signature
Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the CheckSignedInfoKeyedHashAlgorithm method of SignedXml, which compares only the first SignatureValue.Length bytes of the computed HMAC against the supplied signature value. An...
JLSEC-2026-749 HMAC zero-length tag forgery in `EVP_DigestVerifyFinal`, where a zero-length tag could be accepted...
HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...

CVE-2026-44699 LibJWT: Algorithm confusion allows JWT forgery with RSA JWK as empty-key HMAC
LibJWT is a C JSON Web Token Library. From 3.0.0 to 3.3.2, libjwt accepts an RSA JWK that does not contain an alg parameter as the verification key for an HS256/HS384/HS512 token. In the OpenSSL backend, this causes HMAC verification to run with a zero-length key, so an attacker can forge a valid...

Name of the Vulnerable Software and Affected Versions LibJWT versions 3.0.0 through 3.3.2 Description LibJWT accepts an RSA JSON Web Key JWK lacking an alg parameter as the verification key for HS256, HS384, or HS512 tokens. When using the OpenSSL backend, this results in HMAC verification...
CVE-2026-44351
fast-jwt provides fast JSON Web Token JWT implementation. Prior to 6.2.4, a critical authentication-bypass vulnerability in fast-jwt's async key-resolver flow allows any unauthenticated attacker to forge arbitrary JWTs that are accepted as authentic. When the application's key resolver returns an...
