CVE-2026-80110

Summary

A flaw was found in pki-core. The v2 REST ACL filter selects a tie-breaking permission for colliding literal and wildcard ACL keys using lexicographic string comparison rather than specificity, causing a wildcard-mapped permission to override a more specific literal-mapped permission when both match. In the CA's profile-management REST API this allows a request to POST /v2/profiles/raw – intended to require Administrator-level profiles.create permission – to instead be authorized under the lower-privileged profiles.approve permission held by the default Certificate Manager Agents group. The highest threat from this vulnerability is to confidentiality and integrity of the certificate authority's issuance policy.

Weaknesses

  • CWE-863: Incorrect Authorization

Workarounds

There is no way to mitigate this issue other than applying an update once available. As a partial mitigation, limiting membership in the Certificate Manager Agents group to trusted users reduces exposure, since exploitation requires an authenticated credential in that role.
