AI-suggested
1. Upgrade TCPDF to version 6.7.4 or later, where the vulnerability has been addressed. 2. Implement strict input validation and sanitization on all HTML content before it is processed by TCPDF, ensuring that potentially malicious scripts or tags are removed or neutralized. 3. Employ output encoding techniques when rendering HTML content to prevent script execution in client browsers. 4. Use Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of potential XSS attacks. 5. Conduct regular security audits and code reviews of applications integrating TCPDF to identify and remediate unsafe HTML handling. 6. Educate users to be cautious when opening PDF documents from untrusted sources to reduce the risk of social engineering exploitation. 7. Monitor web application logs and network traffic for unusual activity that could indicate exploitation attempts.
Description
TCPDF before 6.7.4 mishandles calls that use HTML syntax.
