{"schemaVersion":3,"id":"CVE-2026-92153","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-10-14T16:28:18.673Z","modified":"2026-10-15T15:07:36.971Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.1,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00437,"percentile":0.36871,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-15T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00437,"percentile":0.36871}],"last30":[{"date":"2026-10-15T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00437,"percentile":0.36871}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')","description":"The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.","type":"weakness","status":"Stable","abstraction":"Base","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/22.html"},{"id":"CWE-73","name":"External Control of File Name or Path","description":"The product allows user input to control or influence paths or file names that are used in filesystem operations.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/73.html"}],"affected":[{"vendor":"nasa","product":"fprime","name":"fprime","label":"fprime","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< 4.3.0","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 4.3.0","eol":null,"hubHref":"/vendor/nasa/fprime"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","label":"github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","hostname":"github.com","tags":["X Refsource CONFIRM"]},{"url":"https://github.com/nasa/fprime/pull/5320","label":"github.com/nasa/fprime/pull/5320","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/nasa/fprime/commit/4c8b9c0b8692b0d47cbd5f2ccec61c74aa02b893","label":"github.com/nasa/fprime/commit/4c8b9c0b8692b0d47cbd5f2ccec61c74aa02b893","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","label":"github.com/nasa/fprime/releases/tag/v4.3.0","hostname":"github.com","tags":["X Refsource MISC"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-14T16:28:18.673Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-15T15:07:36.971Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":28,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T20:10:18.722Z","stale":false,"partial":false}}
