ZITADEL is an open source identity management platform. Prior to 3.4.12 and 4.15.2, ZITADEL's external JWT Identity Provider validation in internal/idp/providers/jwt/session.go skips the maximum token age freshness check when an incoming token omits the iat claim, allowing arbitrarily old tokens...

Hono has improper validation of NumericDate claims (exp, nbf, iat) in JWT verify()

Summary Improper validation of the JWT NumericDate claims exp, nbf, and iat in hono/utils/jwt allows tokens with non-spec-compliant claim values to silently bypass time-based checks. This issue is not exploitable by an anonymous attacker; it only manifests when a malformed claim value reaches...

SUSE CVE-2020-26244

Python oic is a Python OpenID Connect implementation. In Python oic before version 1.2.1, there are several related cryptographic issues affecting client implementations that use the library. The issues are: 1 The IdToken signature algorithm was not checked automatically, but only if the expected...

GHSA-4FJV-PMHG-3RFG Multiple cryptographic issues in Python oic

Impact Client implementations using this library Issues 1 The IdToken signature algorithm was not checked automatically, but only if the expected algorithm was passed in as a kwarg. 2 JWA none algorithm was allowed in all flows. 3 oic.consumer.Consumer.parseauthz returns an unverified IdToken. Th...

Cipher Downgrade Attack

oic is vulnerable to cipher downgrade attacks. The vulnerability exists as the IdToken signature algorithm is not checked automatically, and that the JWA none algorithm is always allowed, and that the IdToken returned from oic.consumer.Consumer.parseauthz is not verified, and the iat claim is not...
