Security readout for executives and security teams
Plain-English summary
CVE-2026-25456 affects the WordPress plugin “Automated FedEx live/manual rates with shipping labels” by Aarsiv Groups. It is a broken access control issue that may allow unauthorized users to perform actions or access data the plugin should restrict. The CVSS score is 7.3, and the issue is rated high. No active exploitation is indicated in the provided sources.
Executive priority
Treat as a high-priority WordPress plugin exposure review, especially for ecommerce sites. Prioritize confirming whether the plugin is installed, whether versions are affected, and whether vendor remediation is available. No active exploitation is confirmed by the provided sources.
Technical view
The CVE describes missing authorization, mapped to CWE-862, in the a2z-fedex-shipping WordPress plugin. Affected versions are listed as through <= 5.1.9. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, indicating remote, unauthenticated exploitability with limited confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely on WordPress sites using the Aarsiv Groups a2z-fedex-shipping plugin at versions up to and including 5.1.9. Internet-facing ecommerce sites using FedEx rate or label functionality should be prioritized for inventory review.
Exploitation context
The source bundle does not report public exploitation, and the CVE is not listed as KEV. The vulnerability is still notable because the scoring indicates unauthenticated network access with low attack complexity and no user interaction.
Researcher notes
There is a version detail mismatch: the CVE description says affected through <= 5.1.9, while the Patchstack URL text references 5.1.8. Rely on the CVE record and vendor/Patchstack updates for final affected-version and remediation confirmation.
Mitigation direction
- Identify WordPress sites using the a2z-fedex-shipping plugin.
- Check installed plugin versions against the affected range through 5.1.9.
- Review vendor and Patchstack guidance for fixed versions or recommended actions.
- Disable the plugin where business impact allows until remediation guidance is confirmed.
- Restrict administrative access and monitor plugin-related activity.
Validation and detection
- Inventory WordPress plugins across production and staging sites.
- Confirm whether a2z-fedex-shipping is installed and active.
- Record the installed plugin version for each site.
- Check CVE and Patchstack pages for updated remediation details.
- Review web logs for unusual access to plugin-related endpoints.
