{"id":"CVE-2021-41119","state":"PUBLISHED","title":"DoS vulnerabiliity in wire-server json parser","description":"Wire-server is the system server for the wire back-end services. Releases prior to v2022-03-01 are subject to a denial of service attack via a crafted object causing a hash collision. This collision causes the server to spend at least quadratic time parsing it which can lead to a denial of service for a heavily used server. The issue has been fixed in wire-server 2022-03-01 and is already deployed on all Wire managed services. On premise instances of wire-server need to be updated to 2022-03-01, so that their backends are no longer affected. There are no known workarounds for this issue.","publishedAt":"2022-04-13T18:25:11.000Z","updatedAt":"2025-04-22T18:16:06.159Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["wireapp wire-server"],"affected":[{"vendor":"wireapp","product":"wire-server","versions":[{"version":"< v2022-03-01","status":"affected"}]}],"references":["https://github.com/wireapp/wire-server/security/advisories/GHSA-phxv-pffh-fq2r","https://cs-syd.eu/posts/2021-09-11-json-vulnerability"],"weaknesses":["CWE-400"],"ingestedAt":"2026-10-29T19:49:01.697Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/41xxx/CVE-2021-41119.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-41119","state":"PUBLISHED","datePublished":"2022-04-13T18:25:11.000Z","dateUpdated":"2025-04-22T18:16:06.159Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2021-09-15T00:00:00.000Z"},"containers":{"cna":{"title":"DoS vulnerabiliity in wire-server json parser","descriptions":[{"lang":"en","value":"Wire-server is the system server for the wire back-end services.
