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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-323"],"vendors":[],"products":[],"references":[{"url":"https://developer.konghq.com/event-gateway/changelog/","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
