CVE-2026-80110
HighCVSS 8.1Summary
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.
Risk Assessment
The vulnerability may allow lower-privileged users to modify the certificate authority's issuance policy. This poses a threat to the confidentiality and integrity of the certificate issuance policy.
Recommendation
Apply available pki-core updates that fix the ACL collision resolution logic. Until patched, consider restricting access to the profile-management REST API or auditing agent group permissions.

- CVE-2026-17039Low
A flaw was found in pki-core where the certificate authority (CA) renewal request path does not perform the realm-based authorization check that the enrollment path performs. This allows an authenticated user entitled to one realm to cause a certificate belonging to a different realm to be renewed without that realm's authorization.

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.
