Forced OGNL evaluation, when evaluated on raw user input in tag attributes, may lead to remote code execution. Affected software : Apache Struts 2.0.0 - Struts 2.5.25.

Apache Struts 2.0.0 to 2.5.20 forced double OGNL evaluation, when evaluated on raw user input in tag attributes, may lead to remote code execution.

An access permission override in Apache Struts 2.0.0 to 2.5.20 may cause a Denial of Service when performing a file upload.

Impact Passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches This problem is patched in jQuery 3.5.0.

Workarounds To workaround the issue without upgrading, adding the following to your code:

js jQuery.htmlPrefilter = function( html ) { return html; };

You need to use at least jQuery 1.12/2.2 or newer to be able to apply this workaround.
