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.","state":0,"publishedAt":"2026-10-06T19:44:03.028+00:00","modifiedAt":"2026-10-07T14:40:22.293+00:00","affected":[{"ecosystem":"Vendor product","name":"stablelib","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"StableLib\",\n                    \"product\": \"stablelib\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.0.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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,"severity":"HIGH"}],"references":["https://github.com/StableLib/stablelib/security/advisories/GHSA-5jg4-p4qw-cgfr","https://github.com/StableLib/stablelib/commit/0149e18d9d4736e22c257744ca945ebce7899a01","https://github.com/StableLib/stablelib/releases/tag/@stablelib/cbor@2.0.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106447","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106447","identifiers":["CVE-2026-106447"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
