CVE Alert: CVE-2025-12925 – rymcu – forest

Risk verdict

High risk due to remote unauthenticated access to the UserDicController endpoints, enabling deletion and other dictionary modifications with no user interaction.

Why this matters

Direct manipulation of dictionary data can disrupt core functionality and data integrity, affecting search, autocomplete, and user workflows. In a rolling-release environment, exposure persists across deployments and patch timing may vary, increasing the window for exploitation and potential follow-on impacts.

Most likely attack path

Exposed API endpoints are reachable over the network and require no authentication, enabling rapid abuse by an external actor. Low complexity and no UI interaction mean an attacker can execute deleteDic/addDic/getAllDic operations to erase or alter data, with potential knock-on effects on service reliability and user experience.

Who is most exposed

Web-facing deployments of API-backed forest components are most at risk, especially SaaS or cloud-hosted instances where the endpoints are publicly reachable and patch cycles are lengthy or opaque.

Detection ideas

• Unexpected calls to deleteDic/addDic/getAllDic without valid authentication.
• spikes in requests to dictionary endpoints outside normal usage patterns.
• repeated authorization failures followed by successful modifications.
• sudden, unexplained deletions or data inconsistencies in dictionary entries.
• anomalous access from new or unusual IPs/user agents.

Mitigation and prioritisation

• Apply available patch/update to affected components; verify in staging before rollout.
• Enforce strong authentication and RBAC on all dictionary endpoints; disable unauthenticated access.
• Add input validation and server-side checks to prevent unauthorized data changes.
• Implement network controls (WAF/IP allowlists) and rate limiting on sensitive endpoints.
• Initiate change-management planning with a hotfix window; monitor dictionary endpoints closely post-deployment.
