medium Tenable Self-Hosted Container Security Plugin ID 443994

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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.
(CVE-2026-48758)

Solution

Update the @sigstore/core library and its related packages to version 3.2.1 or later.
