CVE-2026-106448

StableLib is a stable library of useful TypeScript and JavaScript code. Prior to 2.0.4, the @stablelib/cbor CBOR map decoding path creates ordinary JavaScript objects and assigns attacker-controlled keys with bracket assignment. A map key named proto invokes the inherited prototype setter instead...

CVE-2026-106447

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...

CVE-2026-106448 StableLib: Prototype poisoning via `__proto__` map keys in CBOR decoding

CVE-2026-106448

The @stablelib/cbor component within the StableLib library is vulnerable to prototype poisoning (CWE-1321) in versions prior to 2.0.4 . The root cause lies in the CBOR map decoding path, where the library creates ordinary JavaScript objects and uses bracket assignment for attacker-controlled keys...

CVE-2026-106447 StableLib: Stack exhaustion denial of service via deeply nested CBOR arrays, maps, or tags

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...

CVE-2026-106447

The @stablelib/cbor decoder in StableLib (prior to version 2.0.4 ) is vulnerable to a stack exhaustion denial of service . The root cause is that the _decodeValue() function recursively processes nested CBOR arrays, maps, and tags without enforcing a maximum nesting depth. An attacker providing a...

GHSA-5JG4-P4QW-CGFR @stablelib/cbor: Stack exhaustion Denial of Service via deeply nested CBOR arrays, maps, or tags

Summary @stablelib/cbor decodes nested CBOR structures recursively and does not enforce a maximum nesting depth. A sufficiently deep attacker-controlled CBOR payload can therefore crash decoding with RangeError: Maximum call stack size exceeded. Details The decoder processes arrays, maps, and...

PT-2026-32616

Summary @stablelib/cbor decodes CBOR maps into ordinary JavaScript objects and assigns attacker-controlled keys directly onto those objects. A CBOR map key named proto therefore changes the prototype of the decoded object instead of becoming an ordinary data property. Details The decoder builds m...

Ed25519 Signature Malleability via Missing S = L to prevent signature malleability. When S = L, SB = S mod LB = S - LB, meaning two different 32-byte S values produce the same verification result. An attacker who observes a valid signature R, S can produce a second valid signature R, S + L for th...
