What happened

The wpForo Forum plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.2.2 via the data[secondary_groupids] parameter of the wpforo_action_profile_update POST handler. This is due to a type-confusion flaw in the secondary_groupids authorization guard within the Members::update() function in classes/Members.php, where casting a scalar CSV string (e.g.

"0,1") with (array) before array_map('intval', …) and array_filter() produces an empty array — causing the guard's outer conditional, and the else-branch that would otherwise strip the field from the update, to be bypassed entirely — while encode()/decode() downstream correctly explodes the original CSV and persists the attacker-supplied group IDs to wp_wpforo_profiles.secondary_groupids.

This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their forum privileges to wpForo Administrator by injecting the privileged Admin group ID, granting access to the Forum Accesses editor and the ability to rewrite forum-wide capability policies for all members and edit arbitrary content owned by other users.

Exploitation requires the attacker to have at least 3 approved wpForo posts to satisfy the plugin's default min_number_posts_to_edit_account antispam gate, along with a valid wpforo nonce obtained from their own account profile form.

About this data

This record was ingested from a data source. Retrieved: Nov 7, 2026, 20:21 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
