{"id":"CVE-2026-25727","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-25727","generatedAt":"2026-10-28T08:27:58.663Z","title":"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.","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.","published":"2026-02-06T20:16:12.000Z","lastModified":"2026-06-17T10:25:07.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":6.8,"severity":"MEDIUM","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-121"],"affected":["time project/time"],"epss":{"score":0.00339,"percentile":0.27207,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.34%).
