{"id":"CVE-2026-93561","published":"2026-09-18T11:17:21.650","lastModified":"2026-09-18T21:18:46.847","description":"A flaw was found in io.netty/netty-codec-memcache. The Memcache binary protocol codec incorrectly reads `keyLength` and `extrasLength` as signed Java types instead of unsigned, as specified by the protocol. A malicious Memcache server can exploit this type mismatch by sending a specially crafted response. This can lead to frame desynchronization and response smuggling, where one client's data may be inadvertently exposed to another client's response stream in proxy or cache environments.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-1035"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-93561","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536949","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536949","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
