NVD Description

Note: Versions mentioned in the description apply only to the upstream graalvm-25 package and not the graalvm-25 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.
