{"id":"CVE-2022-22143","aliases":["GHSA-x2w5-725j-gf2g","SNYK-JS-CONVICT-2340604"],"url":"https://o3.security/vulnerability/CVE-2022-22143","summary":"Prototype Pollution","details":"### Impact\n\n* An attacker can inject attributes that are used in other components\n* An attacker can override existing attributes with ones that have incompatible type, which may lead to a crash.\n\nThe main use case of Convict is for handling server-side configurations written by the admins owning the servers, and not random users. So it's unlikely that an admin would deliberately sabotage their own server. Still a situation can happen where an admin not knowledgeable about JavaScript could be tricked by an attacker into writing the malicious JavaScript code into some config files.\n\n### Patches\n\nThe problem is patched in `convict@6.2.3`. Users should upgrade to `convict@6.2.3`.\n\n### Workarounds\n\nNo way for users to fix or remediate the vulnerability without upgrading\n\n### References\n\n* https://www.huntr.dev/bounties/1-npm-convict/\n* #384\n* 3b86be087d8f14681a9c889d45da7fe3ad9cd880\n* 1ea0ab19c5208f66509e1c43b0d0f21c1fd29b75\n\n### For more information\n\nIf you have any questions or comments about this advisory: \nadd your question as a comment in #384 \n","published":"2022-05-01T15:30:45.287Z","modified":"2026-08-12T03:51:27.479789353Z","cvss":{"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"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"npm","name":"convict","fixedVersion":"6.2.3"}],"fix":{"url":"https://github.com/mozilla/node-convict/commit/3b86be087d8f14681a9c889d45da7fe3ad9cd880","label":"mozilla/node-convict@3b86be0"},"references":[{"type":"WEB","url":"https://github.com/mozilla/node-convict/blob/5eb1314f85346760a3c31cb14510f2f0af11d0d3/packages/convict/src/main.js%23L569"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/22xxx/CVE-2022-22143.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-22143"},{"type":"ADVISORY","url":"https://snyk.io/vuln/SNYK-JS-CONVICT-2340604"},{"type":"FIX","url":"https://github.com/mozilla/node-convict/commit/3b86be087d8f14681a9c889d45da7fe3ad9cd880"},{"type":"WEB","url":"https://github.com/mozilla/node-convict/security/advisories/GHSA-x2w5-725j-gf2g"},{"type":"WEB","url":"https://github.com/mozilla/node-convict/pull/384"},{"type":"WEB","url":"https://github.com/mozilla/node-convict"},{"type":"WEB","url":"https://github.com/mozilla/node-convict/releases/tag/v6.2.2"},{"type":"WEB","url":"https://www.huntr.dev/bounties/1-npm-convict"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:27.479789353Z"}}
