# CVE-2026-80110: Pki-core: dogtag pki v2 rest acl filter's reverse-lexicographic tie-break lets a ca agent invoke the admin-only raw profile creation endpoint

Status: published. Published: 2026-09-21. Updated: 2026-11-04.

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.

## Remediation

- workaround: 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.
