## Technical details

Multiple cross-site scripting (XSS) vulnerabilities exist in MoinMoin due to improper sanitization of user-supplied content in the LikePages.py, chart.py, and userprofile.py action modules. These are CWE-79 input validation flaws where crafted HTML or JavaScript can be injected through action parameters. The vulnerability is network-reachable and requires no authentication, but relies on user interaction (a victim must visit a malicious link or perform an action). An attacker can execute arbitrary JavaScript in the context of the victim's browser session. Patches are available in MoinMoin 1.9.3 and later versions.
