{"schema":"threatline.record/2","record":{"id":"CVE-2026-113779","aliases":["GHSA-8q8g-9f77-8g8g"],"summary":"pfSense REST API package Vulnerable to Privilege Escalation via Scoped HA Settings Sync Permission","details":"The pfSense REST API package is an unofficial, open-source REST and GraphQL API for pfSense CE and pfSense Plus firewalls. 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.","categories":["Unclassified"],"product":"pfSense-pkg-RESTAPI","vendor":"pfrest","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-113779","source_modified_at":"2026-10-21T15:47:43.969Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"pfSense-pkg-RESTAPI","vendor":"pfrest","versions":[{"status":"affected","version":"< 2.9.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/pfrest/pfSense-pkg-RESTAPI/security/advisories/GHSA-8q8g-9f77-8g8g","source_modified_at":"2026-10-21T14:04:59Z","fetched_at":"2026-10-23T18:55:00.935475Z","package":{"ecosystem":"other","name":"pfSense-pkg-RESTAPI"},"range":"<=v2.8.4"}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0041,"percentile":0.34131,"score_date":"2026-10-23"},"published_at":"2026-10-21T14:06:33.814Z","modified_at":"2026-10-21T15:47:43.969Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-113779","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T15:47:43.969Z"},{"source":"GitHub Advisory Database","url":"https://github.com/pfrest/pfSense-pkg-RESTAPI/security/advisories/GHSA-8q8g-9f77-8g8g","fetched_at":"2026-10-23T18:55:00.935475Z","source_modified_at":"2026-10-21T14:04:59Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-113779","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/pfrest/pfSense-pkg-RESTAPI/security/advisories/GHSA-8q8g-9f77-8g8g","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/pfrest/pfSense-pkg-RESTAPI/releases/tag/v2.9.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-21T15:06:37.954691Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-21T15:47:43.969Z","content_hash":"7825dbc71b31dd24e9ec11eadc907d6c20266e8f195999d6d0ce00c1450a2aef"}}
