The WP Learn Manager plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.8. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins from the WordPress.org repository on the vulnerable site.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against default configurations of the WP Learn Manager plugin (versions <= 1.1.8) when it is installed and active. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H = 9.8) is internally consistent with the description: network-reachable, no privileges, no user interaction, and high impact to confidentiality, integrity, and availability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts an HTTP request to the site's admin-ajax endpoint invoking the plugin's unauthenticated install-and-activate action, directing WordPress to pull and enable a plugin of the attacker's choosing from the WordPress.org repository. By selecting a plugin with known vulnerabilities (or simply one that broadens attack surface), the attacker pivots toward full site takeover. … |
| Remediation | No vendor-released patch identified at time of analysis - every version through 1.1.8 is affected and no fixed version is stated in the available data, so the primary compensating control is to deactivate and remove the WP Learn Manager plugin until the vendor publishes a fixed release above 1.1.8, tracked via the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/8cbf5121-2511-4e21-a346-67fa1e34fc02?source=cve). … Detailed patch versions, workarounds, and compensating controls in full report. |
