Security readout for executives and security teams
Plain-English summary
CVE-2026-22406 affects the WordPress Overton theme through version 1.3. It is an authorization weakness where a privileged user may access or modify objects they should not control. Business urgency is moderate: impact appears limited, but WordPress sites using this theme should be identified and checked for vendor guidance.
Executive priority
Treat as a scheduled remediation item unless Overton is widely deployed or admin accounts are weakly controlled. Prioritize sites with many privileged users, external administrators, or prior account compromise indicators.
Technical view
The issue is an Insecure Direct Object Reference, CWE-639, in Mikado-Themes Overton. CVSS 3.1 is 5.4: network exploitable, low complexity, high privileges required, no user interaction, low confidentiality and integrity impact, no availability impact. Sources do not provide exploit details or a confirmed fixed version.
Likely exposure
Exposure is limited to WordPress sites running the Overton theme version 1.3 or earlier. The CVSS vector indicates an attacker needs high privileges, reducing broad internet risk but increasing concern for compromised admin accounts or insider misuse.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked as CISA KEV. The vulnerability is remotely reachable but requires high privileges and no user interaction. No public exploit status is established in the supplied evidence.
Researcher notes
Evidence is sparse. The CVE record identifies IDOR and Patchstack is the referenced vulnerability database entry, but the bundle does not include technical request paths, proof of concept, active exploitation, or a named fixed version. Validate affected status carefully before broad action.
Mitigation direction
- Inventory WordPress sites for the Overton theme and version in use.
- Check Mikado-Themes, theme marketplace, and Patchstack guidance for updates or mitigations.
- Update the theme if a vendor-confirmed fixed version is available.
- Remove or disable the theme where it is unused or no longer required.
- Limit high-privilege WordPress accounts to trusted users only.
- Review administrative account security and enforce strong authentication where available.
Validation and detection
- Confirm whether each WordPress site uses Overton version 1.3 or earlier.
- Review theme changelogs or vendor notices for a CVE-2026-22406 fix.
- Check WordPress users with high privileges for unnecessary access.
- Review recent administrative activity for unexpected content or object changes.
- Use non-production testing to verify authorization controls after remediation.
