{"id":"CVE-2026-59873","aliases":["GHSA-23hp-3jrh-7fpw"],"url":"https://o3.security/vulnerability/CVE-2026-59873","summary":"node-tar: Decompression/parse DoS via unlimited input","details":"node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.19, node-tar does not enforce hard upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts, allowing a small crafted gzip bomb to exhaust disk space and CPU. This issue is fixed in version 7.5.19.","published":"2026-07-08T15:22:40.077Z","modified":"2026-08-12T03:51:11.252363185Z","cvss":null,"epss":{"score":0.00556,"percentile":0.43872,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"tar","fixedVersion":"7.5.19"}],"fix":{"url":"https://github.com/isaacs/node-tar/commit/2812e9338665659b183aa7226518c307044957d3","label":"isaacs/node-tar@2812e93"},"references":[{"type":"WEB","url":"https://github.com/isaacs/node-tar/releases/tag/v7.5.19"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59873.json"},{"type":"ADVISORY","url":"https://github.com/isaacs/node-tar/security/advisories/GHSA-23hp-3jrh-7fpw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59873"},{"type":"FIX","url":"https://github.com/isaacs/node-tar/commit/2812e9338665659b183aa7226518c307044957d3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.252363185Z"}}
