Description

MRBS before 1.13.0 contains a CSV formula injection vulnerability that allows authenticated users to inject spreadsheet formulas because the escape() function in web/report.php fails to neutralize leading formula characters. Attackers can store formulas in booking names, descriptions or custom fields that execute when privileged users open exported CSV reports, enabling data exfiltration or command execution via DDE.
