{"schema":"threatline.record/2","record":{"id":"CVE-2026-53582","aliases":["GHSA-xww7-76m6-mh2r"],"summary":"OPNsense: XPATH Injection can disclose any secret in config.xml","details":"OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.10, the Trust module stores attacker-controlled certificate authority and certificate refid values and interpolates them into XPath expressions in src/opnsense/mvc/app/models/OPNsense/Trust/FieldTypes/CAsField.php and src/opnsense/mvc/app/models/OPNsense/Trust/FieldTypes/CertificatesField.php. A user with CA Manager or Certificate Manager privileges can submit a crafted refid and repeatedly retrieve the object to obtain a boolean refcount oracle, allowing values in config.xml to be recovered character by character. Exposed values can include password hashes, API credentials, certificate private keys, VPN key material, and high-availability credentials, enabling privilege escalation and compromise of other security domains. This issue is fixed in version 26.1.10.","categories":["Unclassified"],"product":"core","vendor":"opnsense","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-53582","source_modified_at":"2026-10-16T17:13:42.903Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"core","vendor":"opnsense","versions":[{"version":"< 26.1.10","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00726,"percentile":0.53624,"score_date":"2026-10-23"},"published_at":"2026-10-15T15:08:46.374Z","modified_at":"2026-10-16T17:13:42.903Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-53582","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T17:13:42.903Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-53582","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/opnsense/core/security/advisories/GHSA-xww7-76m6-mh2r","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/opnsense/core/commit/e2cd067343511252fb0d391a17d82d3ecceece45","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/opnsense/core/commit/fc2f0d745c17855d2027b192fd4e3fa913e26859","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":"partial","assessed_at":"2026-10-15T20:24:37.654161Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T17:13:42.903Z","content_hash":"4b0830efdb12ec1061eea6a6febed4069d60cb768944296fb0fad22866bbf85c"}}
