{"id":"CVE-2026-25727","aliases":["GHSA-r6v5-fh4h-64xc","RUSTSEC-2026-0009"],"url":"https://o3.security/vulnerability/CVE-2026-25727","summary":"time affected by a stack exhaustion denial of service attack","details":"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.","published":"2026-02-06T19:20:56.298Z","modified":"2026-07-16T10:14:31.011868781Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"time","fixedVersion":"0.3.47"}],"fix":{"url":"https://github.com/time-rs/time/commit/1c63dc7985b8fa26bd8c689423cc56b7a03841ee","label":"time-rs/time@1c63dc7"},"references":[{"type":"WEB","url":"https://github.com/time-rs/time/blob/main/CHANGELOG.md#0347-2026-02-05"},{"type":"WEB","url":"https://github.com/time-rs/time/releases/tag/v0.3.47"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25727.json"},{"type":"ADVISORY","url":"https://github.com/time-rs/time/security/advisories/GHSA-r6v5-fh4h-64xc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25727"},{"type":"FIX","url":"https://github.com/time-rs/time/commit/1c63dc7985b8fa26bd8c689423cc56b7a03841ee"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-16T10:14:31.011868781Z"}}
