While the specific CVEs and affected versions are not detailed in the source, the vulnerabilities enable a range of attacks including Cross-Site Scripting (XSS), information disclosure, security bypass, and ultimately, arbitrary code execution. Successful exploitation could allow attackers to gain unauthorized access, steal sensitive data, or disrupt services.
