AI-suggested

1. Monitor Priority vendor communications closely and apply security patches immediately once released for versions 23.0 and below. 2. Implement strict input validation and output encoding on all user-supplied data within Priority Web applications to prevent script injection. 3. Enforce the principle of least privilege by limiting user roles and permissions, especially for web application users with elevated rights. 4. Educate users about the risks of interacting with suspicious links or content within the Priority Web environment to reduce the likelihood of triggering malicious scripts. 5. Employ web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting Priority Web. 6. Conduct regular security assessments and code reviews focusing on input handling and sanitization in Priority Web customizations. 7. Enable Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the web application context. 8. Monitor logs and network traffic for unusual activity that could indicate exploitation attempts.
