{"schemaVersion":3,"id":"CVE-2026-5473","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability has been found in NASA cFS up to 7.0.0. The impacted element is the function pickle.load of the component Pickle Module. Such manipulation leads to deserialization. The attack needs to be performed locally. The attack requires a high level of complexity. The exploitability is regarded as difficult. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.","dates":{"published":"2026-04-03T16:30:13.683Z","modified":"2026-04-06T14:51:38.808Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":2,"severity":"low","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.5,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L/E:P/RL:X/RC:R","exploitability":null,"impact":null,"computed":false},{"version":"3.0","versionLabel":"v3.0","source":"CVE.org","score":4.5,"severity":"medium","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L/E:P/RL:X/RC:R","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"CVE.org","score":3.5,"severity":"low","vector":"AV:L/AC:H/Au:S/C:P/I:P/A:P/E:POC/RL:ND/RC:UR","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":1.1,"severity":"low","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7,"severity":"high","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":3.5,"severity":"low","vector":"AV:L/AC:H/Au:S/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00355,"percentile":0.2781,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.132,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00223},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00355,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00355,"percentile":0.2781}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00223,"percentile":null},{"date":"2026-09-24T00:00:00.00
