Security readout for executives and security teams
Plain-English summary
CVE-2026-22356 is a high-severity local file inclusion issue in the WordPress Jetpack CRM plugin, package zero-bs-crm, affecting versions through 6.7.0. If triggered, it could expose or impact sensitive server-side files and application behavior. The public record does not show confirmed active exploitation.
Executive priority
Treat this as a near-term WordPress remediation item for any site using Jetpack CRM. Prioritize externally reachable sites and sites handling customer or CRM data. The urgency is high, but current public evidence does not support claiming active exploitation.
Technical view
The issue is classified as CWE-98: improper control of a filename used in a PHP include/require statement. CVSS 3.1 is 7.5 with network access, high attack complexity, no privileges required, and user interaction required. Reported impacts are high confidentiality, integrity, and availability.
Likely exposure
Exposure is most likely on WordPress sites running Automattic Jetpack CRM / zero-bs-crm at version 6.7.0 or earlier. Sites not using this plugin, or running unaffected versions, are not indicated as exposed by the supplied sources.
Exploitation context
The CVE record does not indicate CISA KEV listing, and the provided sources do not confirm active exploitation. The CVSS vector suggests exploitation is remote but harder to achieve and requires user interaction. No exploit details are provided here.
Researcher notes
The affected range and CWE come from the CVE record and Patchstack reference. The affected version metadata in the source bundle is sparse, so validate against vendor and Patchstack pages before closing. Do not assume a specific fixed version unless confirmed by vendor guidance.
Mitigation direction
- Inventory WordPress sites for the Jetpack CRM / zero-bs-crm plugin.
- Check whether installed versions are 6.7.0 or earlier.
- Review Automattic, WordPress plugin, and Patchstack guidance for fixed versions or mitigations.
- Update the plugin if a vendor-supported fixed release is available.
- If no safe update exists, consider disabling the plugin until vendor guidance is clear.
Validation and detection
- Confirm plugin presence and version from WordPress administration or asset inventory.
- Compare observed versions against the CVE affected range: through 6.7.0.
- Verify remediation by confirming the plugin is updated, disabled, or removed.
- Monitor web and application logs for unusual file-access errors or suspicious plugin requests.

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.
