GHSA-jfc7-64v2-mr8c: @sigstore/core has DSSE payloadType type-binding failureCVE-2026-48758 0 A vulnerability in the @sigstore/core package's preAuthEncoding function allows mutation of the DSSE payloadType after signing without invalidating the signature. This occurs because the function uses Node.js 'ascii' encoding, which truncates characters above U+00FF to their low byte, enabling Unicode characters to produce identical encoded bytes as ASCII characters. This breaks the DSSE type-binding guarantee. The issue affects versions prior to 3.2.1. Join the discussion | GCVE Database | 06/26/2026, 19:11:19 UTC Added: 06/26/2026, 22:05:01 UTC |
