Security readout for executives and security teams
Plain-English summary
LearnDash LMS for WordPress versions up to and including 4.6.0 allowed any logged-in user to change other users' passwords. A low-privileged account could potentially take over an administrator account, leading to full site compromise.
Executive priority
Treat this as a high-priority WordPress plugin remediation if LearnDash LMS is deployed. The business risk is administrator account takeover from a low-privileged account, which can escalate to site control and data exposure.
Technical view
This is a CWE-639 insecure direct object reference in LearnDash LMS authorization handling. The CVSS 3.1 score is 8.8: network exploitable, low complexity, low privileges required, no user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites running LearnDash LMS 4.6.0 or older where an attacker can authenticate with any account level. Sites that allow broad user registration have higher practical risk.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The vulnerability is still serious because it only requires an existing low-privileged account and can lead to administrator takeover.
Researcher notes
The source bundle identifies IDOR/CWE-639 and affected versions through 4.6.0, but does not provide exploit details, a named fixed version, or active exploitation evidence. Validate exposure by version and authentication model, then rely on vendor release notes for remediation confirmation.
Mitigation direction
- Inventory WordPress sites using LearnDash LMS.
- Upgrade LearnDash LMS beyond affected versions using vendor release guidance.
- If upgrade timing is unclear, follow current LearnDash vendor guidance.
- Restrict unnecessary low-privileged account creation until remediation is complete.
- Review administrator accounts for unauthorized password changes.
Validation and detection
- Check installed LearnDash LMS versions across WordPress sites.
- Confirm no production site runs LearnDash LMS 4.6.0 or older.
- Review logs for suspicious password changes or admin logins.
- Verify low-privileged users cannot alter other users' account credentials.
- Document remediation status for each affected WordPress instance.
