Official Description

Bludit version 3.16.1 contains a cross-site request forgery (CSRF) vulnerability in the /admin/uninstall-plugin/ and /admin/install-theme/ endpoints. The application does not implement anti-CSRF tokens or other request origin validation mechanisms for these administrative actions. An attacker can induce an authenticated administrator to visit a malicious page that silently submits crafted requests, resulting in unauthorized plugin uninstallation or theme installation. This may lead to loss of functionality, execution of untrusted code via malicious themes, and compromise of system integrity.

Technical Analysis

CVE-2026-27741 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A proof-of-concept (PoC) exploit exists for CVE-2026-27741. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
