{"id":"CVE-2026-52852","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-52852","generatedAt":"2026-10-27T23:52:00.826Z","title":"Traccar is an open source GPS tracking system.","description":"Traccar is an open source GPS tracking system. Prior to 6.14.0, an authenticated user with permission to manage groups and request reports can create a cyclic group-parent hierarchy and request a trips or stops report for a device in that hierarchy. org.traccar.api.resource.GroupResource permits the parent cycle, while org.traccar.helper.model.AttributeUtil.lookup follows group parents without cycle detection, a visited set, or a depth limit. The storage-backed lookup reached through TripsConfig. and ReportUtils.slowTripsAndStops never terminates, pins a Jetty worker at high CPU after the client disconnects, and can exhaust the web/API worker pool when requests are repeated. The position-ingestion cache-backed path is not part of the confirmed affected scope. This issue is fixed in 6.14.0.","published":"2026-09-17T19:16:50.000Z","lastModified":"2026-09-24T21:25:27.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-674"],"affected":[],"epss":{"score":0.0053,"percentile":0.44573,"date":"2026-10-26","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 (0.53%).
