Security readout for executives and security teams
Plain-English summary
CVE-2026-22345 affects the WordPress “Image Gallery – Lightbox Gallery, Responsive Photo Gallery, Masonry Gallery” plugin through version 1.6.0. It can allow PHP object injection through unsafe deserialization. If exploited, the stated impact is high across confidentiality, integrity, and availability. No provided source confirms active exploitation.
Executive priority
Treat this as a high-priority WordPress plugin exposure. Prioritize internet-facing or business-critical WordPress sites, especially those with multiple user accounts. Because no fixed version is named in the provided sources, the immediate goal is fast inventory, vendor guidance review, and risk-based disablement if needed.
Technical view
The issue is CWE-502, deserialization of untrusted data, in A WP Life’s new-image-gallery WordPress plugin. The CVSS 3.1 score is 8.8: network-accessible, low complexity, low privileges required, and no user interaction. The CVE description states affected versions are through 1.6.0.
Likely exposure
Exposure is likely limited to WordPress sites with the new-image-gallery plugin installed at version 1.6.0 or earlier. The CVSS vector requires low privileges, so sites allowing contributor-level or other low-privileged accounts may have higher practical risk.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. PHP object injection severity often depends on reachable deserialization paths and available gadget chains, so local plugin/theme composition may affect exploitability.
Researcher notes
The source bundle provides the CVE description, CVSS vector, CWE-502 classification, affected plugin name, and Patchstack reference. It does not provide exploit proof, vulnerable function details, fixed version, or vendor changelog evidence. Avoid assuming remote unauthenticated exploitation because CVSS lists PR:L.
Mitigation direction
- Inventory WordPress sites for the new-image-gallery plugin.
- Identify installed plugin versions and flag version 1.6.0 or earlier.
- Check the vendor, WordPress plugin page, or Patchstack for fixed-version guidance.
- If no safe update is available, disable or remove the plugin where feasible.
- Restrict low-privileged WordPress account creation and access until remediated.
Validation and detection
- Confirm whether the plugin package slug is new-image-gallery.
- Record the installed version from WordPress administration or asset inventory.
- Verify whether the site uses version 1.6.0 or earlier.
- Check Patchstack and CVE records for updated remediation details.
- Review WordPress accounts with low-privileged access on affected sites.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
