{"id":"CVE-2026-114230","published":"2026-10-29T11:17:28.210","lastModified":"2026-10-29T15:43:33.310","description":"When dispatching SASL frames to authenticate the peer, Proton will also dispatch AMQP frames if they claim to be SASL frames. This allows authentication bypass. However there will be no user name set so the effects depend on how the application deals with this condition - which otherwise means that authentication has not completed yet.\n\n\n\nThis issue affects Apache Qpid Proton C: through 0.40.0.\n\n\n\nUsers are recommended to upgrade to version 0.41.1, which fixes the issue.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-305"],"vendors":[],"products":[],"references":[{"url":"https://lists.apache.org/thread.html/ob7vo6swpj4wbb2m3zq9q2vkwfg5dg8k","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/10/28/24","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
