{"id":"CVE-2026-111443","published":"2026-10-16T04:18:30.133","lastModified":"2026-10-16T15:19:36.177","description":"Wheels 4.0.6 through 4.1.2 lets an unauthenticated client switch a request into a separate test application context, including in production, by supplying an X-Wheels-Test-Context header or WHEELS_TEST_CONTEXT cookie with any value, or including a test-runner path anywhere in the URL, even the query string. The alternate application uses the same configuration, environment, datasource and debug settings: this is not an authentication bypass or data/debug escalation. It can bypass maintenance mode enabled only at runtime, provide a second set of in-memory rate-limit counters, and trigger additional application-startup side effects and memory use. This is fixed in 4.2.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","cwes":["CWE-348"],"vendors":[],"products":[],"references":[{"url":"https://github.com/wheels-dev/wheels/security/advisories/GHSA-xcj9-wm25-4cg4","tags":[]}],"exploitRefs":[{"url":"https://github.com/wheels-dev/wheels/security/advisories/GHSA-xcj9-wm25-4cg4","tags":[]}],"hasPoc":true,"ai":null}
