{"id":"CVE-2026-111443","details":"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.","aliases":["GHSA-xcj9-wm25-4cg4"],"modified":"2026-10-17T02:48:26.305815037Z","published":"2026-10-16T03:28:28.644Z","database_specific":{"cna_assigner":"mitre","cwe_ids":["CWE-348"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111443.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111443.json"},{"type":"ADVISORY","url":"https://github.com/wheels-dev/wheels/security/advisories/GHSA-xcj9-wm25-4cg4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111443"},{"type":"PACKAGE","url":"https://github.com/wheels-dev/wheels"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wheels-dev/wheels","events":[{"introduced":"5928131df7df785c542dfeae5fd04d916bb49a7e"},{"fixed":"0e589def0922a3f0643cfd17c4ea5fdd8c41b9a6"}],"database_specific":{"extracted_events":[{"introduced":"4.0.6"},{"fixed":"4.2.0"},{"fixed":"4.1.2"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v4.1.2","v4.1.1","v4.1.0","v4.0.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111443.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}
