wpForo 2.4.14 contains an unauthenticated SQL injection vulnerability in Topics::gettopics() where the ORDER BY clause relies on ineffective escsql() sanitization on unquoted identifiers. Attackers exploit the wpfob parameter with CASE WHEN payloads to perform blind boolean extraction of credentials from the WordPress database.

wpForo Forum 2.4.14 contains a missing capability check vulnerability that allows authenticated users to trigger bulk wpForo usergroup reassignment via the wpforosynchroles AJAX handler. Attackers access the usergroups admin page, accessible to any authenticated user, to obtain a nonce, then remap all wpForo usergroups to arbitrary WordPress roles.

wpForo Forum 2.4.14 contains an information disclosure vulnerability that allows unauthenticated users to retrieve private and unapproved forum topics via the global RSS feed endpoint. Attackers request the RSS feed without a forum ID parameter, bypassing the privacy and status WHERE clauses that are only applied when a specific forum ID is present in the query.

wpForo Forum 2.4.14 contains a missing authorization vulnerability that allows authenticated subscribers to move, merge, or split any forum topic via the topicmove, topicmerge, and topicsplit form action handlers. Attackers with a valid form nonce can reorganize arbitrary forum content without moderator permissions, including relocating topics to private forums.

wpForo Forum 2.4.14 contains a missing authorization vulnerability that allows authenticated subscribers to approve or unapprove any forum post via the wpforoapproveajax AJAX handler. Attackers exploit the nonce-only check by submitting a valid nonce with an arbitrary post ID to bypass moderation controls entirely.

wpForo Forum 2.4.14 contains a missing authorization vulnerability that allows authenticated subscribers to close or reopen any forum topic via the wpforocloseajax handler. Attackers submit a valid nonce with an arbitrary topic ID to bypass the moderator permission requirement and disrupt forum discussions.

wpForo Forum 2.4.14 contains a stored cross-site scripting vulnerability that allows authenticated subscribers to upload SVG files as profile avatars through the avatar upload functionality. Attackers upload a crafted SVG containing CSS injection or JavaScript event handlers that execute in the browsers of any user who views the attacker's profile page.

wpForo Forum 2.4.14 contains a stored cross-site scripting vulnerability that allows script injection via forum URL data output into an inline script block using jsonencode without the JSONHEXTAG flag. Attackers set a forum slug containing a closing script tag or unescaped single quote to break out of the JavaScript string context and execute arbitrary script in all visitors' browsers.

wpForo Forum 2.4.14 contains a stored cross-site scripting vulnerability that allows administrators to inject persistent JavaScript via forum description fields echoed without output escaping across multiple theme template files. On multisite installations or with a compromised admin account, attackers set a forum description containing HTML event handlers that execute when any user views the forum listing.
