r0t has reported a vulnerability in ActiveCampaign SupportTrio, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "terms" parameter when performing a search isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
It is reportedly also possible to disclose the full path to "index.php" and "pdf.php" by accessing them with invalid input.
The vulnerability has been reported in version 2.50.2. Other versions may also be affected.
Solution: Update to version 2.50.18 or later.
