Security readout for executives and security teams
Plain-English summary
CVE-2026-25326 affects the WordPress CMSMasters Content Composer plugin through version 1.4.5. A logged-in attacker may be able to make the plugin include local PHP files improperly, potentially exposing data, changing site behavior, or disrupting service. The issue is rated high, but exploitation complexity is high and evidence of active exploitation is not provided.
Executive priority
Treat as a high-priority WordPress plugin issue for sites using CMSMasters Content Composer, especially public sites with many user accounts. Act promptly, but do not treat it as confirmed mass exploitation based on the supplied evidence.
Technical view
The CVE describes CWE-98: improper control of a filename used in PHP include/require logic. It is reported as a Local File Inclusion issue in cmsmasters-content-composer <= 1.4.5. CVSS 3.1 is 7.5: network reachable, high complexity, low privileges required, no user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to WordPress installations running CMSMasters Content Composer version 1.4.5 or earlier. Because CVSS requires low privileges, risk is higher where untrusted users can authenticate to WordPress. The provided sources do not name a fixed version or confirm default vulnerable configurations.
Exploitation context
No CISA KEV listing is indicated, and the supplied sources do not state active exploitation. Exploitation is described as network-accessible but high complexity and requiring a low-privileged account. The public details are limited, so vulnerability managers should avoid assuming unauthenticated exploitation.
Researcher notes
The CVE text references PHP Remote File Inclusion terminology, but the described impact is Local File Inclusion. Sources provide CVSS and affected version range but limited technical detail, no proof-of-concept, no fixed version, and no active exploitation claim.
Mitigation direction
- Inventory WordPress sites for CMSMasters Content Composer installations.
- Prioritize sites running version 1.4.5 or earlier.
- Check CMSMasters or Patchstack guidance for an updated fixed version.
- If no fix is available, disable or remove the plugin where feasible.
- Limit untrusted WordPress accounts until remediation is complete.
Validation and detection
- Confirm whether the plugin is installed on each WordPress site.
- Record the installed plugin version and compare against <= 1.4.5.
- Review vendor or Patchstack advisories for fix availability.
- Check WordPress logs for unusual plugin errors or file inclusion warnings.
- Verify compensating controls after disabling, removing, or updating the plugin.

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.
