An unauthenticated attacker can exploit a discrepancy in how paths are normalized between the security matcher and HTTP request dispatchers. This allows the attacker to craft a URL that the security matcher considers public, but which is then routed to a protected endpoint, leading to an authorization bypass and potential unauthorized access to sensitive information.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-551"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:69440","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:69470","tags":[]},{"url":"https://access.redhat.com/security/cve/CVE-2026-87743","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2530523","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
