CVE-2026-88994— All Bootstrap Blocks 1.3.20 - 1.3.31 - Contributor+ LFI via lightspeed Block Attributes

Quick assessment

Affected
Unknown All Bootstrap Blocks
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

All Bootstrap Blocks WordPress 插件在 1.3.31 及之前版本中，未对块属性进行验证，便将其用于构建文件系统路径，并在渲染时包含该路径。这使得拥有贡献者及以上权限的用户能够包含任意本地文件，披露其内容，并在可以访问包含 PHP 代码的本地文件时执行 PHP 代码。利用该漏洞需要启用插件的“Lightspeed”子系统，而该子系统默认未启用。

Vulnerability Title
All Bootstrap Blocks 1.3.20 - 1.3.31 - Contributor+ LFI via lightspeed Block Attributes
Source: CVE Program / CVE List V5
Vulnerability Description
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.
