CVE-2026-44551 Open WebUI: LDAP Empty Password Authentication Bypass

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the LDAP authentication endpoint does not validate that the submitted password is non-empty before performing a Simple Bind against the LDAP server. The LdapForm Pydantic model accep...

Improper Validation of Array Index

Overview Affected versions of this package are vulnerable to Improper Validation of Array Index through the CertVerifier.Verify function. An attacker can cause the process to panic and exit with a success code by providing a CMS/PKCS7 signed message containing an empty certificate set, which lead...

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...
