CVE-2025-54733

The All Bootstrap Blocks WordPress plugin, versions 1.3.28 and earlier, suffers from a missing authorization vulnerability [1]. The plugin fails to properly check access control security levels, enabling unauthorized exploitation of incorrectly configured access controls.

Attackers can exploit this flaw without authentication, as the missing authorization check allows unprivileged users to perform actions reserved for higher-privileged roles. The attack surface is broad because the vulnerability can be triggered remotely via crafted requests to the plugin's endpoints.

Successful exploitation grants attackers the ability to execute privileged actions, potentially leading to site compromise, data theft, or malicious content injection. Given the widespread use of WordPress plugins, this vulnerability is considered moderately dangerous and is expected to be targeted in mass-exploit campaigns [1].

Mitigation is straightforward: update the plugin to version 1.3.29 or later, which contains the fix [1]. Users of the Patchstack service can also enable the provided mitigation rule to block attacks until the update is applied.
