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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":60,"depthScoreParts":{"impact":47.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":217548,"id":"CVE-2026-106447","ts":1791387417823,"field":"exploit_available","old":"false","new":"true"}]}
