An authorized consumer who detects a nonce collision can recover parts of plaintext from the affected messages.\n\n\n\nNew versions 1.1.2 and 1.2.1 enforce automatic key rotation before the recommended usage limit is reached.","published":"2026-08-05T11:16:25.000Z","lastModified":"2026-10-23T21:10:00.000Z","status":"Awaiting Analysis","sourceIdentifier":"02762ae7-200e-4b20-9b2b-a77d5b8fc4cb","cvss":{"version":"4.0","score":2.3,"severity":"LOW","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-323"],"affected":[],"epss":{"score":0.00244,"percentile":0.15515,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.24%).
