{"id":"CVE-2023-0163","aliases":["GHSA-4jrm-c32x-w4jf"],"url":"https://o3.security/vulnerability/CVE-2023-0163","summary":"Prototype Pollution in convict","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\nThe problem is patched in `convict@6.2.4`. Users should upgrade to `convict@6.2.4`.\n\n### Workarounds\nNo way for users to fix or remediate the vulnerability without upgrading\n\n### References\nhttps://github.com/mozilla/node-convict/issues/410\n","published":"2024-11-26T11:36:26.574Z","modified":"2026-10-28T02:30:24.985244204Z","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"convict","fixedVersion":"6.2.4"}],"fix":{"url":"https://github.com/mozilla/node-convict/commit/fb602fbe1e9f14f2e88ecb8179d0f76466d21ecb","label":"mozilla/node-convict@fb602fb"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/0xxx/CVE-2023-0163.json"},{"type":"ADVISORY","url":"https://github.com/mozilla/node-convict/security/advisories/GHSA-4jrm-c32x-w4jf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-0163"},{"type":"REPORT","url":"https://github.com/mozilla/node-convict/issues/410"},{"type":"WEB","url":"https://github.com/mozilla/node-convict/commit/fb602fbe1e9f14f2e88ecb8179d0f76466d21ecb"},{"type":"PACKAGE","url":"https://github.com/mozilla/node-convict"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:24.985244204Z"}}
