Summary
Bludit CMS before version 3.18.4 allows Remote Code Execution (RCE) via the API Plugin. The POST /api/files/{key} endpoint in bl-plugins/api/plugin.php fails to perform authorization checks and lacks file extension validation.
Risk Assessment
An attacker with a valid API token can upload a malicious PHP script and execute arbitrary code on the server, posing a serious security threat to the system.
Recommendation
It is recommended to update Bludit CMS to version 3.18.4 or later and implement additional authorization verification and file extension validation mechanisms.
Other vulnerabilities in Bludit CMS
See all- CVE-2026-93366Medium
Bludit CMS through 3.22.0 contains an authorization bypass vulnerability that allows authenticated users with the Author role to enumerate and delete media files belonging to pages owned by other users, including administrators, by supplying arbitrary uuid parameters to unprotected AJAX endpoints. Attackers can retrieve page UUIDs for all users via the content-get-list endpoint and then submit crafted POST requests to the list-images and delete-image endpoints in bl-kernel/ajax/ to access and destroy media files outside their own pages, bypassing the IMAGE_RESTRICT isolation control.
- CVE-2026-93365Medium
Bludit CMS through 3.22.0 contains a missing authorization vulnerability that allows authenticated users holding the Author or Editor role to read the full content of private drafts and scheduled posts belonging to any other user, including administrators, by exploiting the content-get-list AJAX endpoint.
- CVE-2026-93364Medium
Bludit CMS through 3.22.0 contains a mass assignment vulnerability that allows authenticated users with the Author role to modify privileged page fields reserved for administrators by injecting reserved parameters into a content save request, enabling page conversion or ownership transfer.
- CVE-2026-41456Medium
Bludit CMS prior to commit 6732dde contains a reflected cross-site scripting vulnerability in the search plugin that allows unauthenticated attackers to inject arbitrary JavaScript by crafting a malicious search query. Attackers can execute malicious scripts in the browsers of users who visit crafted URLs containing the payload, potentially stealing session cookies or performing actions on behalf of affected users.
