Description

When one Disclosure in an SD-JWT presentation is tampered so its digest no longer matches the Issuer-signed _sd array, @sd-jwt/decode 0.19.0 does not reject the presentation. It silently drops the unmatched Disclosure and returns a reduced claim set, reporting success. The Issuer signature is untouched and valid.

Recommendation

Update the @sd-jwt/core package to the latest compatible version. Followings are version details:

  • Affected version(s): <= 0.19.0
  • Patched version(s): 0.20.0
