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.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-80110","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2523749","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The flaw in pki-core allows wildcard ACL permissions to override more specific literal permissions, potentially enabling unauthorized access to certificate management functions.","exploitability":"Exploitation requires knowledge of the affected API and permission levels; preconditions include access to the CA's profile-management REST API.","blast_radius":"If exploited, this could lead to unauthorized changes in the certificate authority’s issuance policy, compromising confidentiality and integrity.","remediation":"Update pki-core to a patched version or apply vendor-provided patches immediately.","tags":["acl","permission","api","certificate","security"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:07:45.306Z"}}
