CVE-2026-88994: CWE-98 Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') in All Bootstrap Blocks
The All Bootstrap Blocks WordPress plugin through 1.3.31 does not validate a block attribute before using it to build a filesystem path that is included at render time, allowing users with contributor-level access and above to include arbitrary local files, disclose their contents, and execute PHP where a local file containing PHP code can be reached. Exploitation requires the plugin's Lightspeed subsystem to be enabled, which is not the default.
AI Analysis
Technical Summary
CVE-2026-88994 is a remote file inclusion vulnerability in the All Bootstrap Blocks WordPress plugin (versions >=1.3.20 <=1.3.31). The plugin fails to validate a block attribute used to build a filesystem path that is included during rendering. This improper control of filename for include/require statements (CWE-98) allows authenticated users with contributor-level privileges or higher to include arbitrary local files, leading to local file disclosure and remote code execution if the included file contains executable PHP code. The vulnerability requires the Lightspeed subsystem to be enabled, which is off by default.
Potential Impact
An attacker with contributor-level access or higher can exploit this vulnerability to include arbitrary local files on the server, potentially disclosing sensitive information and executing arbitrary PHP code. This can lead to full compromise of the affected WordPress site. However, exploitation requires the Lightspeed subsystem of the plugin to be enabled, reducing the attack surface since it is not enabled by default.
Mitigation Recommendations
No official patch or fix is currently documented. Users should verify if the Lightspeed subsystem is enabled and consider disabling it if not required. Monitor the vendor's advisory for updates and apply any official patches once released. Until then, restrict contributor-level access to trusted users only and consider removing or replacing the plugin if possible.
