{"id":"CVE-2026-73566","summary":"node-tar: Uncontrolled recursion in mapHas/filesFilter allows uncatchable stack-overflow DoS via crafted long-path tar with member selection","details":"node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname() and no segment cap when tar.t(...) or tar.x(...) receives a non-empty member-selection list. A crafted GNU L or PAX x long-path header with thousands of slash-separated segments reaches this.filter(entry.path, entry) in Parser[CONSUMEHEADER] in src/parse.ts before Unpack[CHECKPATH] applies maxDepth, causing an uncatchable RangeError stack overflow that terminates asynchronous and streaming Node.js consumers. This issue is fixed in version 7.5.21.","aliases":["GHSA-r292-9mhp-454m"],"modified":"2026-08-19T03:31:03.257111635Z","published":"2026-08-13T17:39:05.796Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-400","CWE-674"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73566.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73566.json"},{"type":"ADVISORY","url":"https://github.com/isaacs/node-tar/security/advisories/GHSA-r292-9mhp-454m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73566"},{"type":"FIX","url":"https://github.com/isaacs/node-tar/commit/631ae59121bf8fc8a22bbae35f074cb9b789cd4a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/isaacs/node-tar","events":[{"introduced":"0"},{"fixed":"631ae59121bf8fc8a22bbae35f074cb9b789cd4a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"7.5.21"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v7.5.20","v7.5.19","v7.5.18","v7.5.17","v7.5.16","v7.5.15","v7.5.14","v7.5.13","v7.5.12","v7.5.11","v7.5.10","v7.5.9","v7.5.8","v7.5.7","v7.5.6","v7.5.5","v7.5.4","v7.5.3","v7.5.2","v7.5.1","v7.5.0","v7.4.4","v7.4.3","v7.4.2","v7.4.1","v7.4.0","v7.3.0","v7.2.0","v7.1.0","v7.0.1","v7.0.0","v6.2.1","v6.2.0","v6.1.15","v6.1.14","v6.1.13","v6.1.12","v6.1.11","v6.1.10","v6.1.9","v6.1.8","v6.1.7","v6.1.6","v6.1.5","v6.1.4","v6.1.3","v6.1.2","v6.1.1","v4.4.13","v5.0.5","v6.1.0","v6.0.5","v6.0.4","v6.0.3","v6.0.2","v6.0.1","v6.0.0","v5.0.2","v5.0.4","v5.0.3","v5.0.1","v4.4.12","v4.4.11","v4.4.10","v4.4.9","v2.2.1","v4.4.8","v4.4.7","v4.4.6","v4.4.5","v4.4.4","v4.4.3","v4.4.2","v4.4.1","v4.4.0","v4.3.3","v4.3.2","v4.3.1","v4.3.0","v4.2.0","v4.1.2","v4.1.1","v4.1.0","v4.0.2","v4.0.1","v3.2.0","v4.0.0","v3.1.15","v3.1.14","v3.1.13","v3.1.12","v3.1.11","v3.1.10","v3.1.9","v3.1.8","v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.1","v3.0.0","v2.1.1","v2.1.0","v2.0.1","v2.0.0","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.1.20","v0.1.19","v0.1.18","v0.1.17","v0.1.16","v0.1.15","v0.1.14","0.1.13","0.1.12","0.1.11","0.1.10","0.1.9","0.1.8","0.1.7","0.1.6","0.1.5","0.1.3","0.1.2","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73566.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
