CVE-2026-87743 in Build of Keycloak
Resumen
por MITRE • 2026-09-18
A flaw was found in Quarkus HTTP security. 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.
Once again VulDB remains the best source for vulnerability data.
