{"schema":"threatline.record/2","record":{"id":"CVE-2026-92153","aliases":["GHSA-5rfj-hw2g-vwmv"],"summary":"F´: Arbitrary File Write in Svc::FileUplink via attacker-controlled StartPacket.destinationPath","details":"F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileUplink handling of Fw::FilePacket::StartPacket destination paths FileUplink copies the packet-controlled destinationPath and opens it for writing without canonicalization or confinement to an upload directory. When a peer able to send file-uplink packets supplies an absolute, traversing, or otherwise attacker-selected writable destination path, files can be created or overwritten at attacker-selected writable filesystem locations, affecting integrity and potentially availability. This issue is fixed in version 4.3.0.","categories":["Unclassified"],"product":"fprime","vendor":"nasa","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92153","source_modified_at":"2026-10-15T15:07:36.971Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"fprime","vendor":"nasa","versions":[{"status":"affected","version":"< 4.3.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","source_modified_at":"2026-09-15T22:57:45Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"","name":"fprime"},"range":"all versions containing the current Svc::FileUplink behavior"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","source_modified_at":"2026-09-15T22:57:45Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"","name":"fprime"},"version":"4.3"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00437,"percentile":0.36945,"score_date":"2026-10-23"},"published_at":"2026-10-14T16:28:18.673Z","modified_at":"2026-10-15T15:07:36.971Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92153","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:07:36.971Z"},{"source":"GitHub Advisory Database","url":"https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","fetched_at":"2026-10-23T19:58:35.668311Z","source_modified_at":"2026-09-15T22:57:45Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92153","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/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/pull/5320","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/commit/4c8b9c0b8692b0d47cbd5f2ccec61c74aa02b893","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","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":"partial","assessed_at":"2026-10-15T13:52:12.083583Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:07:36.971Z","content_hash":"a1fed4214173907a12e410539866fe22822311b5b190f175029fe921be7bec7f"}}
