CVE-2024-36522Network attack vector

Remote code execution via insecure XSLT processing

Published Jul 12, 2024 · Updated Feb 13, 2025

XSLT injection in Apache Wicket 8.0.0 through 8.15.0, 9.0.0 through 9.17.0, and 10.0.0-M1 through 10.0.0 allows remote attackers to execute code. The default XSLTResourceStream configuration passes unvalidated, attacker-controlled transformation input to an XSLT processor without enabling secure processing. Exploitation requires a consuming application to route remote input into this class; successful injection runs code with the application process's privileges.
