Risk Assessment The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N scores 7.5 and indicates network-reachable, low-complexity, unauthenticated exploitation with high confidentiality impact but no integrity or availability impact - consistent with an information disclosure flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated remote attacker sends crafted HTTP requests directly to vulnerable wpForo Forum endpoints on a target WordPress site, bypassing membership or board-level access controls to retrieve forum posts, topics, or user information that should be restricted to logged-in members. Because exploitation requires no authentication or user interaction and the attack complexity is low, the attacker can script the request against many WordPress sites running the plugin to harvest private discussion content at scale.
Remediation Upgrade the wpForo Forum plugin to version 3.0.2 or later through the WordPress admin plugin update mechanism - this is the vendor-released patch and the primary fix. … Detailed patch versions, workarounds, and compensating controls in full report.
