nodejs24: sigstore-js provides JavaScript libraries for interacting with Sigstore services
CVE-2026-48758 is fixed in 10 products on 1 platform, first by ALAS2023-2026-1920, released July 6, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
