CVE-2026-40767

There is a vulnerability in wpForo Forum versions up to 3.1.0 related to unauthenticated broken authentication.

There is an unauthenticated PHP Object Injection vulnerability in wpForo Forum versions <= 3.1.0.

There is an unauthenticated SQL injection vulnerability in wpForo Forum versions up to 3.0.4.

The wpForo Forum plugin for WordPress has missing authorization, allowing exploitation of incorrectly configured access control security levels.

The wpForo Forum plugin for WordPress up to version 2.4.17 is vulnerable to SQL Injection via the 'referer' parameter. Insufficient escaping and lack of preparation on the SQL query allow unauthenticated attackers to append additional SQL queries, which can be used to extract sensitive information from the database.

The wpForo Forum WordPress plugin before 3.1.3 does not restrict which profile fields a member may set when editing their own account. This allows subscriber-level users to write administrator-controlled account-state and reputation fields on their own profile, including self-activating a pending or banned account and forging their forum reputation score.

The wpForo Forum WordPress plugin before 3.1.2 does not sanitize and escape a user profile field before outputting it inside an HTML attribute on the public participant profile page, allowing users with a subscriber-level account to inject JavaScript that executes in the browser of any visitor who views the profile, including a logged-in administrator.

The wpForo Forum WordPress plugin before 3.1.2 does not verify that an AI chat conversation belongs to the requesting user before deleting its messages, allowing users with a subscriber-level account to permanently delete the stored AI chat message history of any other user.

The wpForo Forum plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'location' Profile Field in all versions up to and including 3.1.1 due to insufficient input sanitization and output escaping. This allows authenticated attackers with subscriber-level access or higher to inject arbitrary web scripts that execute whenever a user accesses an injected page.

The wpForo Forum plugin version 3.0.9 and earlier contains a SQL injection vulnerability exploitable by contributors. An attacker with contributor privileges can inject malicious SQL queries, potentially leading to unauthorized database access.
