{"schemaVersion":3,"id":"CVE-2026-106550","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Mozilla's Node-convict (version 6.2.2 and later) is vulnerable to a Denial of Service vulnerability caused by incomplete prototype‑pollution protections in config.set(). An attacker controlling the configuration key can write arbitrary properties to constructor.<key>, which walk() resolves to the global Object function. This allows overwriting core JavaScript methods such as Object.assign, leading to persistent process-wide failures and requiring a restart. The issue bypasses existing filters that only block constructor.prototype.* and __proto__.*. Exploitation requires an endpoint that forwards attacker-controlled keys into config.set().","dates":{"published":"2026-10-06T20:09:55.919Z","modified":"2026-10-07T19:33:03.505Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00284,"percentile":0.1965,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-07T00:00:00.000Z","score":0.00241,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00284,"percentile":0.1965}],"last30":[{"date":"2026-10-07T00:00:00.000Z","score":0.00241,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00284,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00284,"percentile":0.1965}]},"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-400","name":"Uncontrolled
