AI-suggested

European organizations should prioritize updating Ghost to version 5.76.0 or later, where this vulnerability is fixed. In the absence of an immediate patch, administrators should implement input sanitization and output encoding on post excerpts to prevent script injection. Employing Content Security Policy (CSP) headers can help mitigate the impact by restricting the execution of unauthorized scripts. Additionally, organizations should review user permissions to limit who can create or edit posts, reducing the attack surface. Regular security awareness training for users to recognize suspicious content and avoid interacting with untrusted excerpts is advisable. Monitoring web application logs for unusual activity related to post excerpts can help detect attempted exploitation. Finally, consider deploying web application firewalls (WAFs) with rules targeting XSS payloads in URL parameters or post content to provide an additional layer of defense.

Description

Ghost before 5.76.0 allows XSS via a post excerpt in excerpt.js. An XSS payload can be rendered in post summaries.
