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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-674"],"references":["https://github.com/StableLib/stablelib/commit/0149e18d9d4736e22c257744ca945ebce7899a01","https://github.com/StableLib/stablelib/releases/tag/@stablelib/cbor@2.0.4","https://github.com/StableLib/stablelib/security/advisories/GHSA-5jg4-p4qw-cgfr","https://github.com/StableLib/stablelib/security/advisories/GHSA-5jg4-p4qw-cgfr"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-106447","score":0.00471,"percentile":0.405,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5jg4-p4qw-cgfr","url":"https://osv.dev/vulnerability/GHSA-5jg4-p4qw-cgfr","summary":"@stablelib/cbor: Stack exhaustion Denial of Service via deeply nested CBOR arrays, maps, or tags","modified":"2026-10-07T10:56:09.289175299Z","packages":[{"ecosystem":"npm","name":"@stablelib/cbor","purl":"pkg:npm/%40stablelib/cbor","ranges":["<2.0.3"],"fixed":["2.0.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
