NVD Description

Note: Versions mentioned in the description apply only to the upstream kyverno-fips-1.18 package and not the kyverno-fips-1.18 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Fulcio is a certificate authority for issuing code signing certificates for an OpenID Connect (OIDC) identity. Versions through 1.8.5 improperly follow cross-host redirects and attach Kubernetes ServiceAccount tokens during OIDC discovery, allowing a malicious or compromised issuer to perform blind SSRF, substitute and cache malicious JWKS keys, or disclose ServiceAccount tokens to external hosts. Version 1.8.6 blocks cross-host redirects, restricts token injection, and restricts local token loading. No known workarounds are available.
