The Academy LMS - WordPress LMS Plugin for Complete eLearning Solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.8.1. This is due to the '/topics' REST API endpoint being registered with a permission callback set to '__return_true', allowing unauthenticated access to course curriculum data without verifying the course's post status or user enrollment. This makes it possible for unauthenticated attackers to access detailed curriculum information for private, draft, scheduled, or password-protected courses by enumerating course IDs.
AnalysisAI
Unauthenticated curriculum exposure in the Academy LMS WordPress plugin (versions ≤ 3.8.1) allows any internet user to retrieve detailed topic and lesson structures from courses explicitly protected by private, draft, scheduled, or password-protected post statuses. The root cause is the plugin's '/topics' REST API endpoint registering with '__return_true' as its permission callback, entirely bypassing WordPress's built-in post visibility and enrollment enforcement. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The WordPress REST API must be accessible over the network - this is the default state for all WordPress installations unless explicitly disabled via a firewall or plugin. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) accurately reflects the limited blast radius: confidentiality impact is Low because only course curriculum structure (topic and lesson metadata) is disclosed, not user PII, payment data, or authentication credentials. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker scripts sequential HTTP GET requests to '/wp-json/academy/v1/topics?course_id=N' against a target WordPress site, incrementing the course ID integer with each request. For each protected course (private, draft, or password-protected), the server returns the full curriculum outline including topic titles and lesson structure without any authentication check, enrollment verification, or rate-limiting enforced by the plugin. … |
| Remediation | Update the Academy LMS plugin to the first release above version 3.8.1 that incorporates changeset 3592849 from the WordPress plugin trac repository - verify the exact version number in the plugin's changelog before updating, as the precise released patch version is not confirmed in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
