Title: Forced OGNL evaluation, when evaluated on raw not validated user input in tag attributes, may lead to RCE. (CVE-2021-31805)
Description:The fix issued for CVE-2020-17530 was incomplete. So from Apache Struts 2.0.0 to 2.5.29, still some of the tag’s attributes could perform a double evaluation if a developer applied forced OGNL evaluation by using the %{...} syntax. Using forced OGNL evaluation on untrusted user input can lead to a Remote Code Execution and security degradation.
