A flaw was found in Quarkus in versions through 2.16.10.Final, 3.0.0.Alpha1 through 3.2.5.Final, 3.3.0.CR1 through 3.3.2 and 3.4.0.CR1 through 3.4.0 where HTTP security policies are not sanitizing certain character permutations correctly when accepting requests, resulting in incorrect evaluation of permissions. This issue could allow an attacker to bypass the security policy altogether, resulting in unauthorized endpoint access and possibly a Denial-Of-Service (DoS).
CWE-863 - Incorrect Authorization
Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
