Security readout for executives and security teams
Plain-English summary
A WordPress plugin called WPCOM Member may let an authenticated user make the site include local server files. That can expose sensitive data, alter behavior, or disrupt the site. The CVE rates this high risk, but the provided sources do not show confirmed active exploitation.
Executive priority
Treat this as a near-term remediation item for any production WordPress site using WPCOM Member. Prioritize sites with customer logins, public registration, sensitive files, or compliance obligations.
Technical view
CVE-2025-39570 is a CWE-98 filename-control flaw in Lomu WPCOM Member for WordPress through version 1.7.7. The CVSS 3.1 score is 8.8, with network access, low complexity, low privileges, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to WordPress sites running the wpcom-member plugin at version 1.7.7 or earlier. The CVSS vector indicates the attacker needs low privileges, so public registration or weak account governance increases concern.
Exploitation context
The source bundle says KEV is false and provides no cited evidence of active exploitation. The issue is still serious because local file inclusion can expose sensitive files or affect PHP execution paths depending on deployment and plugin behavior.
Researcher notes
The provided affected metadata is sparse, but the description and title identify WPCOM Member through 1.7.7. No exploit details, proof of concept, or fixed version are included in the bundle, so avoid claims beyond confirmed LFI risk and CVSS characteristics.
Mitigation direction
- Inventory WordPress sites for the wpcom-member plugin and versions.
- Disable or remove WPCOM Member where it is not business-critical.
- Check Patchstack and vendor guidance for fixed versions or official workarounds.
- Restrict low-privileged account creation and plugin access until remediated.
- Monitor WordPress and PHP logs for unusual file access errors.
Validation and detection
- Confirm whether wpcom-member is installed on each WordPress property.
- Record installed plugin versions and flag version 1.7.7 or earlier.
- Verify whether untrusted users can obtain low-privileged site accounts.
- Review security advisories for any official patch status changes.
- Use only approved, non-invasive scanner checks or vendor validation guidance.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
