Security readout for executives and security teams

Plain-English summary

CVE-2023-25799 is a high-severity authorization flaw in Themeum Tutor LMS for WordPress. A logged-in low-privilege user could access actions they should not control, risking course or site data integrity and availability. The provided sources identify Tutor LMS through 2.1.8, with incomplete version evidence requiring confirmation against vendor guidance.

Executive priority

Treat this as a priority patching item for any public or customer-facing WordPress learning portal using Tutor LMS. Business impact is mainly unauthorized modification or disruption of LMS functions, not confirmed mass exploitation.

Technical view

The issue is CWE-862 Missing Authorization in Tutor LMS. CVSS 3.1 is 8.3 with network access, low complexity, low privileges, no user interaction, and high integrity and availability impact. The bundle describes multiple broken access control vulnerabilities affecting Tutor LMS through 2.1.8.

Likely exposure

Exposure is likely limited to WordPress sites running Themeum Tutor LMS with vulnerable versions installed, especially where untrusted or numerous users can log in with low privileges.

Exploitation context

The CVE is not listed in KEV, and the provided sources do not state active exploitation. Risk is higher for public learning portals because exploitation requires only authenticated low-privilege access, not administrator access.

Researcher notes

Version evidence is incomplete: the bundle states through 2.1.8, while the Patchstack reference URL mentions 2.1.10. Do not assume exploitability outside the cited affected range without vendor confirmation.

Mitigation direction

  • Inventory WordPress sites for the Tutor LMS plugin and installed version.
  • Check Themeum and Patchstack guidance for the fixed version before closing remediation.
  • Upgrade Tutor LMS if vendor guidance confirms the installed version is vulnerable.
  • Restrict course platform accounts to trusted users until remediation is complete.
  • Review Tutor LMS permissions and remove unnecessary low-privilege accounts.

Validation and detection

  • Confirm whether Tutor LMS is installed on each WordPress site.
  • Record the exact plugin version from WordPress administration or asset inventory.
  • Compare the version against CVE and vendor advisory affected-version statements.
  • Review user roles with Tutor LMS access for unnecessary privileges.
  • Check logs for unusual low-privilege user actions affecting courses or LMS settings.
