Security readout for executives and security teams
Plain-English summary
CVE-2026-22500 is a critical vulnerability in the WordPress m2 | Construction and Tools Store theme. A remote attacker may be able to inject PHP objects through unsafe deserialization. The published score is 9.8, indicating potential full confidentiality, integrity, and availability impact. No provided source confirms active exploitation.
Executive priority
Treat as urgent for any public WordPress site using this theme. The vulnerability is rated critical and requires no authentication or user interaction. If the theme is absent, business risk from this CVE is not indicated by the provided sources.
Technical view
The issue is CWE-502, Deserialization of Untrusted Data, affecting axiomthemes m2 | Construction and Tools Store theme package m2-ce through version 1.1.2. The CVSS vector is AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, meaning network-reachable, unauthenticated, low-complexity exploitation with no user interaction.
Likely exposure
Exposure is limited to WordPress installations using the m2 | Construction and Tools Store theme, m2-ce, through version 1.1.2. Internet-facing WordPress sites using this theme should be prioritized because the CVSS vector indicates unauthenticated network access.
Exploitation context
The sources describe PHP object injection from unsafe deserialization but do not provide exploit details. CISA KEV status is false in the provided bundle, and no cited source confirms exploitation in the wild.
Researcher notes
The record names the affected product and class but does not include a fixed version, exploit chain, or proof of exploitation. Avoid assuming gadget availability or remote code execution without additional evidence from vendor or researcher publications.
Mitigation direction
- Inventory WordPress sites for the m2-ce theme and its installed version.
- Check the vendor and Patchstack entry for a fixed version or official mitigation.
- Disable or remove the theme where it is not business-critical.
- Prioritize compensating controls for internet-facing affected sites until vendor guidance is applied.
- Back up sites before making theme or production changes.
Validation and detection
- Confirm whether m2 | Construction and Tools Store theme is installed.
- Verify whether the installed theme version is 1.1.2 or earlier.
- Review vendor and Patchstack advisories for current remediation status.
- Check web application logs for unusual requests targeting theme functionality.
- Document affected sites, owners, exposure, and remediation status.
