{"id":"CVE-2023-42444","url":"https://www.cyber-defence.io/tools/cve/CVE-2023-42444","generatedAt":"2026-10-28T02:14:50.951Z","title":"Prior to versions `0.3.3+8.13.9` and `0.2.5+8.11.3`, the phonenumber parsing code may panic due to a panic-guarded out-of-bounds access on the phonenumber string.","description":"phonenumber is a library for parsing, formatting and validating international phone numbers. Prior to versions `0.3.3+8.13.9` and `0.2.5+8.11.3`, the phonenumber parsing code may panic due to a panic-guarded out-of-bounds access on the phonenumber string. In a typical deployment of `rust-phonenumber`, this may get triggered by feeding a maliciously crafted phonenumber over the network, specifically the string `.;phone-context=`. Versions `0.3.3+8.13.9` and `0.2.5+8.11.3` contain a patch for this issue. There are no known workarounds.","published":"2023-09-19T15:15:57.000Z","lastModified":"2026-06-17T06:23:51.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-248","CWE-392","CWE-1284"],"affected":["whisperfish/phonenumber"],"epss":{"score":0.00867,"percentile":0.58451,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.87%).
