Security readout for executives and security teams
Plain-English summary
This CVE affects the WordPress ContentMX Content Publisher plugin through version 1.0.6. A logged-in user with low privileges may be able to perform actions that should require stronger authorization, potentially changing content or disrupting plugin behavior.
Executive priority
Treat as a moderate WordPress exposure. It is not currently sourced as exploited, but authenticated access-control flaws can affect content integrity and operations. Prioritize externally used sites with many user accounts.
Technical view
CVE-2025-31555 is a CWE-862 missing authorization issue in contentmx-content-publisher. The CVSS 3.1 score is 5.4: network-reachable, low complexity, low privileges required, no user interaction, with low integrity and availability impact and no confidentiality impact.
Likely exposure
Exposure is limited to WordPress sites running ContentMX Content Publisher version 1.0.6 or earlier, especially sites with multiple low-privileged user accounts. The supplied data does not confirm affected CPEs or exact vulnerable actions.
Exploitation context
The CVE is not marked in CISA KEV, and the supplied sources do not cite active exploitation. The vulnerability requires an authenticated low-privileged user, so risk is higher where contributor, subscriber, customer, or contractor accounts exist.
Researcher notes
Evidence is limited to the CVE record and Patchstack listing. The supplied bundle does not describe the vulnerable endpoint, exact capability bypass, proof of concept, exploit activity, or confirmed fixed version.
Mitigation direction
- Inventory WordPress sites for the ContentMX Content Publisher plugin.
- Check vendor or Patchstack guidance for a fixed release or official workaround.
- Remove or disable the plugin where it is not business-critical.
- Limit WordPress accounts and roles to trusted users only.
- Monitor plugin-related content changes until remediation is confirmed.
Validation and detection
- Confirm whether contentmx-content-publisher is installed on each WordPress site.
- Record plugin versions and compare against the <= 1.0.6 affected range.
- Review low-privileged accounts that can access WordPress admin features.
- Check logs for unexpected publishing, configuration, or plugin activity.
