Low risk17th percentile - higher than 17% of all known CVEs
Summary
In the Joomla Events Manager extension before version 5.0.1, there is a reflected XSS vulnerability via the PDF export link. The buildCurrentPdfLink function copies the current request query string into the PDF button URL, and pdfbutton() echoes it unescaped, leading to a reflected XSS vector.
Risk Assessment
The risk is the possibility of executing malicious script in the victim's browser, which could lead to session theft, account takeover, or other attacks.
Recommendation
It is recommended to update the Joomla Events Manager extension to version 5.0.1 or later and avoid clicking suspicious PDF export links.
