A vulnerability in log file viewer of Wildfly server 10.x.x allowing arbitrary file read to authenticated attacker via path traversal was found.

It was found in Undertow before 1.3.28 that with non-clean TCP close, the Websocket server gets into infinite loop on every IO thread, effectively causing DoS.

It was found that the AJP connector in undertow does not use the ALLOWENCODEDSLASH option and thus allow the the slash / anti-slash characters encoded in the url which may lead to path traversal and result in the information disclosure of arbitrary local files.

admin-cli before versions 3.0.0.alpha25, 2.2.1.cr2 is vulnerable to an EAP feature to download server log files that allows logs to be available via GET requests making them vulnerable to cross-origin attacks. An attacker could trigger the user's browser to request the log files consuming enough resources that normal server functioning could be impaired.

A flaw was found in Wildfly, where it returns an incorrect caller principal under certain heavily concurrent situations when Elytron Security is used. This flaw allows an attacker to gain improper access to information they should not have.
