CVE-2026-38329: n/a
Bludit CMS versions prior to 3.18.4 contain a critical remote code execution vulnerability in the API Plugin. The vulnerability exists because the POST /api/files/{key} endpoint does not perform proper authorization checks and lacks file extension validation. An attacker with a valid API token can upload a malicious PHP script and execute arbitrary code on the server, leading to full compromise.
AI Analysis
Technical Summary
CVE-2026-38329 affects Bludit CMS before version 3.18.4. The vulnerability is located in the API Plugin's file upload endpoint (POST /api/files/{key} in bl-plugins/api/plugin.php), which fails to enforce authorization and does not validate file extensions. This allows an attacker possessing a valid API token to upload and execute arbitrary PHP code remotely, resulting in remote code execution (RCE). The CVSS v3.1 base score is 9.8, indicating a critical severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an attacker with a valid API token to execute arbitrary code on the server hosting Bludit CMS. This can lead to full system compromise, data theft, data modification, or service disruption. The vulnerability affects confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict API token issuance and usage to trusted users only. Monitor for suspicious API activity and consider disabling the vulnerable API Plugin if feasible.
