This allows attackers to create new valid signatures different from previous signatures for a known message.\n\ud83d\udccf Published: 2025-03-13T00:00:00.000Z\n\ud83d\udccf Modified: 2025-03-13T05:20:08.585Z\n\ud83d\udd17 References:\n1. https://github.com/str4d/ed25519-java/issues/82#issue-727629226\n2. https://eprint.iacr.org/2020/1244", "creation_timestamp": "2025-03-13T05:44:21.000000Z"}
