Security readout for executives and security teams
Plain-English summary
CVE-2026-0953 is a critical login bypass in the Tutor LMS Pro WordPress plugin. Sites using the Social Login addon on versions up to 3.9.5 may let an unauthenticated attacker sign in as an existing user, including an administrator. This could lead to full site compromise.
Executive priority
Treat as urgent for any revenue, education, or member portal using Tutor LMS Pro Social Login. The vulnerability can enable administrator takeover without prior access, creating high risk to site integrity, user data, and business operations.
Technical view
Tutor LMS Pro fails to verify that the email in a Social Login authentication request matches the email in the validated OAuth token. An attacker with their own valid OAuth token could target another existing account email. The issue is classified as CWE-287 with CVSS 9.8.
Likely exposure
WordPress sites running Tutor LMS Pro up to and including 3.9.5, especially where the Social Login addon is enabled. Administrative accounts are in scope if their email addresses are known.
Exploitation context
The CVE record indicates network-based, low-complexity exploitation requiring no privileges or user interaction. The provided sources do not state active exploitation, and this CVE is not marked KEV in the bundle.
Researcher notes
The source bundle clearly describes the vulnerable condition and versions through 3.9.5. It does not provide exploit-in-the-wild evidence or detailed fixed-version text. The affected metadata appears sparse, so prioritize vendor and Wordfence confirmation during triage.
Mitigation direction
- Check Tutor LMS vendor guidance and the referenced release notes immediately.
- Upgrade Tutor LMS Pro beyond 3.9.5 if a fixed version is available.
- Disable the Social Login addon until remediation is confirmed.
- Review administrator accounts and enforce strong account recovery controls.
- Restrict WordPress admin access where operationally feasible.
Validation and detection
- Inventory WordPress sites using Tutor LMS Pro.
- Confirm installed Tutor LMS Pro version on each site.
- Determine whether the Social Login addon is enabled.
- Review recent logins for unexpected administrator access.
- Confirm remediation against vendor release notes or Wordfence guidance.
