{"id":"BIT-rabbitmq-2026-67224","summary":"RabbitMQ: Admin path-traversal write via trace name","details":"RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.1, The trace consumer constructs the output path as filename:join(TraceDir, Name ++ \".log\") where Name comes from PUT /api/traces/:vhost/:name. No safe_relative_path / traversal check is applied on the write side, while the read side (rabbit_tracing_files.erl) does call rabbit_misc:safe_relative_path/1 , proving the omission is an oversight, not design. The .log suffix is forced and the endpoint requires administrator. A user with the administrator tag can write a .log-suffixed file to an arbitrary filesystem path writable by the rabbitmq user via the tracing plugin's name parameter, e.g. /etc/cron.d/x.log (if writable) or overwrite existing .log files outside the trace directory. Preconditions include rabbitmq_tracing plugin enabled administrator tag Target path writable by rabbitmq OS user. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.1.","aliases":["CVE-2026-67224","GHSA-h7cq-qrr8-7vgc"],"modified":"2026-10-20T10:30:04.922751300Z","published":"2026-10-01T09:33:13.511Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:vmware:rabbitmq:*:*:*:*:*:*:*:*"]},"references":[{"type":"ARTICLE","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6"},{"type":"ARTICLE","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.3.1"},{"type":"ADVISORY","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-h7cq-qrr8-7vgc"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67224"}],"affected":[{"package":{"name":"rabbitmq","ecosystem":"Bitnami","purl":"pkg:bitnami/rabbitmq"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.13.0"},{"fixed":"3.13.15"},{"introduced":"4.0.0"},{"fixed":"4.0.20"},{"introduced":"4.1.0"},{"fixed":"4.1.11"},{"introduced":"4.2.0"},{"fixed":"4.2.6"},{"introduced":"4.3.0"},{"fixed":"4.3.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/rabbitmq/BIT-rabbitmq-2026-67224.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N"}]}],"schema_version":"1.9.1"}
