ZITADEL: Missing Token Expiration (`exp`) Validation in JWT IdP Provider PUBLISHED

Description (CNA)

ZITADEL is an open source identity management platform. Prior to 3.4.12 and 4.15.2, ZITADEL is an open source identity management platform. From 3.0.0-rc.1 through 3.4.11 and from 4.0.0-rc.1 through 4.15.1, ZITADEL's external JWT Identity Provider validation in internal/idp/providers/jwt/session.go skips expiration handling when an incoming token omits the exp claim, allowing a token from a trusted issuer to be treated as valid without an automatic expiration window. This issue is fixed in versions 3.4.12 and 4.15.2.
