Security readout for executives and security teams
Plain-English summary
CVE-2023-6751 lets an unauthenticated attacker toggle maintenance mode in the Hostinger WordPress plugin through a missing authorization check. Business impact is mainly website disruption and unauthorized settings changes, with limited confidentiality and integrity impact reflected in the CVSS score.
Executive priority
Prioritize remediation for public WordPress sites because the bug can be used without login and can disrupt site availability. It is not proven actively exploited in the supplied evidence, but the ease of abuse justifies near-term patching or disabling on exposed sites.
Technical view
The issue is CWE-862 in the publish_website function of Hostinger Tools for WordPress, affecting versions up to and including 1.9.7. The vulnerable path lacks a capability check, allowing unauthenticated maintenance mode enablement or disablement. CVSS 3.1 is 7.3, network-accessible, low complexity, no privileges, no user interaction.
Likely exposure
Exposure is limited to WordPress sites running the Hostinger plugin or Hostinger Tools at version 1.9.7 or earlier. The bundle does not establish exposure for unrelated Hostinger services or non-WordPress products.
Exploitation context
The CVE is not listed as CISA KEV in the bundle, and no provided source states active exploitation. The issue is remotely reachable and unauthenticated, so internet-facing WordPress sites using the affected plugin should be treated as plausible targets.
Researcher notes
Evidence supports missing authorization on publish_website and unauthorized maintenance mode toggling. The supplied affected metadata is inconsistent, showing product Hostinger Tools with version 0 while the description and title state versions through 1.9.7. Treat exact product naming as needing vendor confirmation.
Mitigation direction
- Inventory WordPress sites for Hostinger Tools or the Hostinger plugin.
- Upgrade affected installations to a vendor-confirmed version newer than 1.9.7.
- If no confirmed fix is available, follow Hostinger and WordPress plugin guidance.
- Disable the plugin where business impact allows until remediation is confirmed.
- Review maintenance mode settings after remediation.
Validation and detection
- Confirm installed plugin names and versions across all WordPress environments.
- Flag any Hostinger plugin or Hostinger Tools version 1.9.7 or earlier.
- Check whether maintenance mode was unexpectedly enabled or disabled.
- Review WordPress and web logs for suspicious unauthenticated settings changes.
- Verify anonymous users cannot modify plugin maintenance settings after remediation.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
