  - A security feature bypass vulnerability exists. An attacker can exploit this and bypass the security
    feature and perform unauthorized actions compromising the integrity of the system/application. (CVE-2023-33170)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
