## Technical details

The "return" parameter in Event Gallery is base64-decoded and directly output into a "Back" link without validation, creating both reflected XSS and open redirect vulnerabilities. Attackers can craft malicious URLs to inject JavaScript code that executes in victims' browsers or redirect users to arbitrary external sites. The vulnerability affects Event Gallery versions before 6.5.0 and requires only network access to exploit via a crafted link sent to a victim.
