GHSA-w48f-fwg7-ww6p

HIGH

@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.

Affected: < 2.0.3, >=0, <2.0.3
Fixed in: 2.0.3
Weakness: CWE-1321
