CVE-2024-1133: Tutor LMS <= 2.6.0 - Missing Authorization

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized access of restricted Q&A content due to a missing capability check when interacting with questions in all versions up to, and including, 2.6.0. This makes it possible for authenticated attackers, with subscriber access or higher, to interact with questions in courses in which they are not enrolled including private courses.

Security readout for executives and security teams

Plain-English summary

Tutor LMS for WordPress allowed logged-in low-privilege users to access or interact with restricted course Q&A content for courses they were not enrolled in, including private courses. The known impact is limited data exposure, not site takeover or service disruption.

Executive priority

Treat this as a moderate-priority privacy and access-control issue. Prioritize remediation for paid, private, compliance-sensitive, or partner-only learning portals where restricted Q&A content may contain confidential business, student, or customer information.

Technical view

CVE-2024-1133 is a CWE-862 missing authorization issue in Tutor LMS up to and including 2.6.0. An authenticated attacker with subscriber-level access or higher could interact with restricted question content outside their enrolled courses. CVSS 3.1 is 4.3 with low attack complexity and confidentiality impact only.

Likely exposure

Exposure is limited to WordPress sites running Tutor LMS versions 2.6.0 or earlier where untrusted or broadly registered users can authenticate, such as public learning portals, membership sites, or customer training sites.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Abuse requires an authenticated account, but subscriber access may be easy to obtain on sites with open registration.

Researcher notes

Evidence supports unauthorized interaction with restricted Q&A content by authenticated subscriber-level users. Sources do not indicate integrity or availability impact, public exploit availability, or active exploitation. The referenced WordPress changeset is relevant for reviewing the authorization fix, but operational validation should avoid offensive testing.

Mitigation direction

  • Update Tutor LMS to a version later than 2.6.0 following vendor guidance.
  • Disable open registration if subscriber accounts are not required.
  • Review course privacy settings and Q&A access assumptions.
  • Limit user roles to the minimum needed for learners.
  • Monitor vendor advisories for explicit fixed-version guidance.

Validation and detection

  • Inventory WordPress sites using Tutor LMS and record plugin versions.
  • Flag any Tutor LMS installation at version 2.6.0 or earlier.
  • Check whether public or low-trust users can create subscriber accounts.
  • Review logs for unusual Q&A interactions by unenrolled users.
  • Confirm updated code includes authorization checks around question interactions.
