An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

Cross-Site Request Forgery (CSRF) in Apache Roller 6.1.5 allows a remote attacker to cause a logged-in user to perform state-changing actions under the victim's authority, because the CSRF validation filters accept a request that does not submit the required salt token, validating instead against a value the server itself generated for the request. No optional feature or non-default configuration is required; any logged-in author or administrator is affected when induced to visit a crafted page. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which validates only the submitted salt and applies the same check to multipart forms.

An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines until it ships, then apply the release.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
