Name of the Vulnerable Software and Affected Versions SOPlanning versions prior to 1.56

Description Reflected Cross-Site Scripting (XSS) occurs when an application includes untrusted data in a web page without proper validation or escaping. An attacker can craft a malicious URL containing the taches parameter which, when opened by an authenticated victim, results in arbitrary JavaScript execution in the victim’s browser.

Recommendations Update to a version later than 1.55. As a temporary workaround, avoid using the taches parameter until the issue is resolved.
