{"id":"CVE-2026-25727","state":"PUBLISHED","title":"time affected by a stack exhaustion denial of service attack","description":"time provides date and time handling in Rust. From 0.3.6 to before 0.3.47, when user-provided input is provided to any type that parses with the RFC 2822 format, a denial of service attack via stack exhaustion is possible. The attack relies on formally deprecated and rarely-used features that are part of the RFC 2822 format used in a malicious manner. Ordinary, non-malicious input will never encounter this scenario. A limit to the depth of recursion was added in v0.3.47. From this version, an error will be returned rather than exhausting the stack.","publishedAt":"2026-02-06T19:20:56.298Z","updatedAt":"2026-02-06T20:22:58.488Z","severity":{"score":6.8,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["time-rs time"],"affected":[{"vendor":"time-rs","product":"time","versions":[{"version":">= 0.3.6, < 0.3.47","status":"affected"}]}],"references":["https://github.com/time-rs/time/security/advisories/GHSA-r6v5-fh4h-64xc","https://github.com/time-rs/time/commit/1c63dc7985b8fa26bd8c689423cc56b7a03841ee","https://github.com/time-rs/time/blob/main/CHANGELOG.md#0347-2026-02-05","https://github.com/time-rs/time/releases/tag/v0.3.47"],"weaknesses":["CWE-121"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/25xxx/CVE-2026-25727.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-25727","state":"PUBLISHED","datePublished":"2026-02-06T19:20:56.298Z","dateUpdated":"2026-02-06T20:22:58.488Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-05T16:48:00.426Z"},"containers":{"cna":{"title":"time affected by a stack exhaustion denial of service attack","descriptions":[{"lang":"en","value":"time provides date and time handling in Rust.
