Prior to 2.7.1, GuardDog's safe_extract() function does not validate decompressed file sizes when extracting ZIP archives (wheels, eggs), allowing attackers to cause denial of service through zip bombs. A malicious package can consume gigabytes of disk space from a few megabytes of compressed data. This vulnerability is fixed in 2.7.1.","published":"2026-01-13T20:43:43.132Z","modified":"2026-08-07T11:50:38.117629209Z","cvss":null,"epss":{"score":0.00431,"percentile":0.35411,"asOf":"2026-08-05"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"guarddog","fixedVersion":"2.7.1"}],"fix":{"url":"https://github.com/DataDog/guarddog/commit/c3fb07b4838945f42497e78b7a02bcfb1e63969b","label":"DataDog/guarddog@c3fb07b"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22870.json"},{"type":"ADVISORY","url":"https://github.com/DataDog/guarddog/security/advisories/GHSA-ffj4-jq7m-9g6v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22870"},{"type":"FIX","url":"https://github.com/DataDog/guarddog/commit/c3fb07b4838945f42497e78b7a02bcfb1e63969b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:38.117629209Z"}}
