Summary

The frontend topic editing flow does not verify on the server side that the requesting visitor owns the topic being modified. A visitor who knows a topic identifier from the public forum can submit a modified update request directly and overwrite its content without ownership confirmation. Topic identifiers are publicly visible, and exploitation requires no privileged access or non-default configuration.

Risk Assessment

An attacker can overwrite the content of any forum topic, leading to data integrity violation and potential injection of malicious content.

Recommendation

Add server-side ownership verification for all topic edit and update operations to ensure the requester owns the resource.

Original NVD description (English source)

The frontend topic editing flow does not verify on the server side that the requesting visitor owns the topic being modified. As a result, a visitor who knows the identifier of a topic from the public forum can submit a modified update request for that topic directly and overwrite its content, without the application confirming ownership. Topic identifiers are visible in the public forum listing, and exploitation requires no privileged access or non-default configuration.
