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 a wildcard ACL to override a more specific literal ACL, potentially allowing a lower-privileged group to perform actions intended for a higher-privileged group, compromising the certificate authority's issuance policy.","exploitability":"Exploitation requires knowledge of the affected API and the ability to craft a request that matches both a wildcard and a literal ACL. The precondition is that the Certificate Manager Agents group holds the lower-privileged permission.","blast_radius":"If exploited, this vulnerability could lead to unauthorized changes in the certificate authority's issuance policy, impacting confidentiality and integrity.","remediation":"Disable the affected v2 REST ACL filter or upgrade to the latest version of pki-core that addresses this issue.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","acl","rest-api","pki"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-03T09:06:07.289Z"}}
