This update addresses a critical Cross-Site Request Forgery (CSRF) vulnerability, identified as CVE-2024-46911.

Details on CVE-2024-46911

This vulnerability affects Apache Roller versions prior to 6.1.4. In multi-user settings, users are typically trusted to publish various content types. However, the previous lack of robust CSRF protection allowed potential privilege escalation. Dave Johnson, Vice President of Apache Roller, explained that this vulnerability created risks on platforms with multiple users, making this update critical.

Key Enhancements in Apache Roller 6.1.4

Apache Roller 6.1.4 offers essential improvements to increase security and prevent attacks:

Safer Defaults: The update now sanitizes HTML content, blocking malicious code from executing. By default, custom themes and file uploads are also disabled, preventing unauthorized content.
Enhanced CSRF and XSS Protections: Apache has introduced protections to guard against CSRF and Cross-Site Scripting (XSS) attacks. They use user-specific and one-time-use salts to secure all interactions.
Updated Dependencies: Apache updated over 20 third-party libraries, including Spring, Log4j, and Lucene, to strengthen overall security.
