CVE-2022-36100Public exploitNetwork attack vector

Remote code execution via unescaped tag rendering

Published Sep 8, 2022 · Updated Apr 22, 2025

Eval injection in XWiki Platform 1.7 through 13.10.5 and 14.0 through 14.3 allows remote attackers to execute code via a crafted tag. Main.Tags inserts the tag request value into XWiki syntax without escaping it, causing embedded Groovy, Python, or Velocity directives to be evaluated with programming rights. View rights suffice, including guest access on public wikis and authenticated access on private wikis, enabling rights bypass and disclosure, modification, or interruption of wiki content.
