CVE-2026-106447: Stablelib

High severity, CVSS 8.7. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

• Stablelib Stablelib: before 2.0.4 (fixed in 2.0.4)
