This issue has been addressed in version 1.1.4. Users are advised to upgrade. There are several ways to workaround or lower the probability of this bug affecting a given deployment. 1: use a reasonably high `POLL_TIMEOUT` setting, like the default. 2: use separate libmemcached connections for unrelated data. 3: do not re-use libmemcached connections in an unknown state.","published":"2023-03-07T18:15:09.000Z","lastModified":"2026-06-17T05:45:18.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"cwe":["CWE-200"],"affected":["awesome/libmemcached"],"epss":{"score":0.00749,"percentile":0.54441,"date":"2026-10-23","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 (0.75%).
