NVD Description

Note: Versions mentioned in the description apply only to the upstream pulumi package and not the pulumi package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.2.1, the preAuthEncoding function in @sigstore/core uses Node.js ascii encoding when converting the PAE string to bytes, allowing payloadType to be mutated after signing without invalidating the signature and breaking the type-binding guarantee that DSSE is designed to provide. This issue is fixed in version 3.2.1.
