A privilege escalation vulnerability in pfSense-pkg-RESTAPI prior to version 2.9.0 allows authenticated accounts holding the dedicated settings sync permission to modify REST API configuration secrets. This enables a non-administrative user to elevate their privileges to a full administrator. pfSense-pkg-RESTAPI 2.9.0 patches the issue. Access to the HA settings sync endpoint now strictly requires full administrative privileges (`page-all`). The sub-administrative sync privilege has been removed in versions v2.9.0 and later. In addition to correcting the access control boundary, version 2.9.0 includes the following hardening measures: opt-in default and format and validation modernization. As a workaround, one may mitigate exposure by taking either or all of the following steps. Revoke Scoped Permissions: Remove the `api-v2-system-restapi-settings-sync-post` privilege from all non-administrative users. Apply ACLs: Configure REST API Access Control Lists (ACLs) and/or firewall rules to restrict access to API endpoints exclusively to trusted administrator and HA peer IP addresses.","state":0,"publishedAt":"2026-10-21T14:06:33.814+00:00","modifiedAt":"2026-10-21T15:47:43.969+00:00","affected":[{"ecosystem":"Vendor product","name":"pfSense-pkg-RESTAPI","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"pfrest\",\n                    \"product\": \"pfSense-pkg-RESTAPI\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.9.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/pfrest/pfSense-pkg-RESTAPI/security/advisories/GHSA-8q8g-9f77-8g8g","https://github.com/pfrest/pfSense-pkg-RESTAPI/releases/tag/v2.9.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113779","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113779","identifiers":["CVE-2026-113779"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
