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().","state":0,"publishedAt":"2026-10-06T20:09:55.919+00:00","modifiedAt":"2026-10-07T19:33:03.505+00:00","affected":[{"ecosystem":"Vendor product","name":"Node-convict","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Mozilla\",\n                    \"product\": \"Node-convict\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"6.2.2\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/mozilla/node-convict","https://github.com/tomasilluminati/security-research/blob/main/CVE-2026-106550/README.md"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106550","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106550","identifiers":["CVE-2026-106550"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
