{"id":"CVE-2026-92153","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.","aliases":["GHSA-5rfj-hw2g-vwmv"],"modified":"2026-10-15T02:49:35.086575353Z","published":"2026-10-14T16:28:18.673Z","database_specific":{"cwe_ids":["CWE-22","CWE-73"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92153.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92153.json"},{"type":"FIX","url":"https://github.com/nasa/fprime/commit/4c8b9c0b8692b0d47cbd5f2ccec61c74aa02b893"},{"type":"FIX","url":"https://github.com/nasa/fprime/pull/5320"},{"type":"WEB","url":"https://github.com/nasa/fprime/releases/tag/v4.3.0"},{"type":"ADVISORY","url":"https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92153"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nasa/fprime","events":[{"introduced":"0"},{"fixed":"7d8f579f159d2f7c2d4984d92828575e37f87fa6"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.3.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v4.3.0b1","v4.3.0a1","v4.2.0","v4.2.0a1","v4.1.1","v4.1.0","v4.0.1a1","v4.0.0a3","v4.0.0","v4.0.0a2","v4.0.0a1","v3.6.0","v3.5.1","v3.5.0","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.2","v3.3.1","v3.3.0","v3.2.0","v3.1.1","v3.1.0","v3.0.0","NASA-v1.5.3","NASA-v1.5.2","NASA-v1.5.1","NASA-v1.5.0","NASA-v1.3.1","NASA-v1.00"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92153.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L"}]}
