Versions of astral-tokio-tar prior to 0.5.6 contain a boundary parsing vulnerability that allows attackers to smuggle additional archive entries by exploiting inconsistent PAX/ustar header handling. When processing archives with PAX-extended headers containing size overrides, the parser incorrectly advances stream position based on ustar header size (often zero) instead of the PAX-specified size, causing it to interpret file content as legitimate tar headers. This issue has been patched in version 0.5.6. There are no workarounds.","state":0,"publishedAt":"2025-10-21T17:15:40.563+00:00","modifiedAt":"2026-10-08T11:10:00.25+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1,"severity":"HIGH"}],"references":["https://edera.dev/stories/tarmageddon","https://github.com/astral-sh/tokio-tar/commit/22b3f884adb7a2adf1d3a8d03469533f5cbc8318","https://github.com/astral-sh/tokio-tar/security/advisories/GHSA-j5gw-2vrg-8fgx","https://github.com/astral-sh/uv/security/advisories/GHSA-w476-p2h3-79g9","https://github.com/edera-dev/cve-tarmageddon"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-62518","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-843"],"productCriteria":[],"sourceDates":{"published":"2025-10-21T17:15:40.563","lastModified":"2026-10-08T11:10:00.250"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
