   Hi,   
      
   The following vulnerability was published for golang-filippo-edwards25519.   
      
   CVE-2026-26958[0]:   
   | filippo.io/edwards25519 is a Go library implementing the   
   | edwards25519 elliptic curve with APIs for building cryptographic   
   | primitives. In versions 1.1.0 and earlier, MultiScalarMult produces   
   | invalid results or undefined behavior if the receiver is not the   
   | identity point. If (*Point).MultiScalarMult is called on an   
   | initialized point that is not the identity point, it returns an   
   | incorrect result. If the method is called on an uninitialized point,   
   | the behavior is undefined. In particular, if the receiver is the   
   | zero value, MultiScalarMult returns an invalid point that compares   
   | Equal to every other point. Note that MultiScalarMult is a rarely   
   | used, advanced API. For example, users who depend on   
   | filippo.io/edwards25519 only through github.com/go-sql-driver/mysql   
   | are not affected. This issue has been fixed in version 1.1.1.   
      
   As described from upstream, MultiScalarMult is a rearely used,   
   advanced API. But I noticed that we have the same version across   
   bookworm up to unstable, it might be a good idea to rebase unstable's   
   version for aim to include in forky to a recent version.   
      
   If you fix the vulnerability please also make sure to include the   
   CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
