{"schema":"threatline.record/2","record":{"id":"CVE-2026-106447","aliases":["GHSA-5jg4-p4qw-cgfr"],"summary":"StableLib: Stack exhaustion denial of service via deeply nested CBOR arrays, maps, or tags","details":"StableLib is a stable library of useful TypeScript and JavaScript code. Prior to 2.0.4, the @stablelib/cbor decoder recursively processes nested CBOR arrays, maps, and tags through _decodeValue() without enforcing a maximum nesting depth. A sufficiently deep structure exhausts the JavaScript call stack, causing a decoding exception and potentially terminating an uncaught request worker or process. This issue is fixed in version 2.0.4.","categories":["Libraries & packages"],"product":"stablelib","vendor":"StableLib","ecosystem":"npm","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-106447","source_modified_at":"2026-10-07T14:40:22.293Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"stablelib","vendor":"StableLib","versions":[{"version":"< 2.0.4","status":"affected"}],"defaultStatus":null},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-5jg4-p4qw-cgfr","source_modified_at":"2026-10-07T10:56:09.289175299Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"@stablelib/cbor","ecosystem":"npm","purl":"pkg:npm/%40stablelib/cbor"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.0.3"}]}],"versions":[]}],"fixed_versions":[{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-5jg4-p4qw-cgfr","source_modified_at":"2026-10-07T10:56:09.289175299Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"@stablelib/cbor","ecosystem":"npm","purl":"pkg:npm/%40stablelib/cbor"},"version":"2.0.3"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00371,"percentile":0.29882,"score_date":"2026-10-23"},"published_at":"2026-10-06T19:44:03.028Z","modified_at":"2026-10-07T14:40:22.293Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-106447","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T14:40:22.293Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-5jg4-p4qw-cgfr","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T10:56:09.289175299Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-106447","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/StableLib/stablelib/security/advisories/GHSA-5jg4-p4qw-cgfr","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/StableLib/stablelib/commit/0149e18d9d4736e22c257744ca945ebce7899a01","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/StableLib/stablelib/releases/tag/@stablelib/cbor@2.0.4","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-07T14:39:46.797113Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-07T14:40:22.293Z","content_hash":"7073f7c3b2ddd09e511a5c5034daf117589a829b5b0f51ebf9ffc44b58ee603c"}}
