CVE-2005-3417
HighSummary
phpBB 2.0.17 and earlier, when the register_long_arrays directive is disabled, allows remote attackers to modify global variables and bypass security mechanisms because PHP does not define the associated HTTP_* variables.
Risk Assessment
An attacker can take control of the application by modifying critical global variables, leading to data integrity breaches and potential user session hijacking.
Recommendation
It is recommended to upgrade phpBB to version 2.0.18 or later and enable the register_long_arrays directive in PHP configuration if feasible.

In @fastify/middie versions >= 9.1.0 and before 9.3.4, the decision to run path-scoped middleware is made by matching against the raw request target, while the Fastify router resolves an absolute-form request target to its path before dispatching. Because the two layers evaluate different strings, a request using an absolute-form target reaches the route handler while the path-scoped middleware, such as authentication or authorization, is skipped. An unauthenticated network attacker can use this to bypass path-based access controls in a Fastify application that relies on middie for those controls.

The AI Website Builder WordPress plugin (GitHub build) 1.0.0 does not perform any authorisation or nonce check on its REST API routes, allowing unauthenticated attackers to install and activate plugins and themes, import content from a URL under their control, write a file of their choosing into the uploads directory, and delete site content and media. On a host that serves PHP from the uploads directory, that file write is remote code execution.

- CVE-2026-15354Critical
The ACPT (Premium) plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.0.66. This is due to missing authorization in the `submit()` function, which allows unauthenticated form submissions to control the target user ID before calling `wp_update_user()`. This makes it possible for unauthenticated attackers to overwrite any WordPress user's email address and password, including an administrator's, and take over the account. Successful exploitation requires a public ACPT user form that permits anonymous submissions.
