What happened
The media upload workflow relies on an incomplete file-type validation sequence for authenticated editors.
Affected versions
ExampleCMS: ≤ 2.6.3 Fixed: 2.6.4.
Why it matters
Content-management systems frequently expose uploaded content through the web tier, increasing the impact of policy bypasses.
Detection & mitigation
- Upgrade to ExampleCMS 2.6.4.
- Restrict editor roles.
- Store uploaded files outside executable web paths.
