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.","state":0,"publishedAt":"2026-10-14T16:28:18.673+00:00","modifiedAt":"2026-10-15T15:07:36.971+00:00","affected":[{"ecosystem":"Vendor product","name":"fprime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nasa\",\n                    \"product\": \"fprime\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.3.0\",\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:N/I:H/A:L","score":7.1,"severity":"HIGH"}],"references":["https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","https://github.com/nasa/fprime/pull/5320","https://github.com/nasa/fprime/commit/4c8b9c0b8692b0d47cbd5f2ccec61c74aa02b893","https://github.com/nasa/fprime/releases/tag/v4.3.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92153","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92153","identifiers":["CVE-2026-92153"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
