CVE-2025-22424: Input Validation
In multiple locations, there is a possible way to reveal images across users due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Implement server-side input validation and sanitize all image-related request parameters. Enforce authorization (ownership) checks before returning or revealing images to ensure a user can only access their own images. Reject or normalize any requests that could reference other users' images.
Web application (image serving component) input_validation and authorization checks = server-side validation and per-user ownership checks - Compensating control
Restrict access to image endpoints until application fixes are deployed: require authentication for all image requests, enforce strict ACLs on image storage, use signed/time-limited URLs or proxy image access through an authenticated service, and apply web application firewall rules to block requests that attempt to access other users' images.
Event History
Frequently Asked Questions
What level of access does an attacker need to exploit this issue?
The attacker needs local access with low privileges. Exploitation also requires user interaction, but no additional execution privileges are needed.
What is the potential impact if exploitation succeeds?
An attacker may be able to reveal images belonging to other users. The issue can lead to local privilege escalation and affects confidentiality, integrity, and availability at high impact levels.
