Security readout for executives and security teams
Plain-English summary
CVE-2022-1918 affects the WordPress ToolBar to Share plugin through version 2.0. A malicious site or link could abuse an administrator’s logged-in session to change plugin settings and inject script into the WordPress site.
Executive priority
Treat as high priority for WordPress environments using this plugin. The business risk is site compromise through administrator targeting, not broad automatic exploitation based on the supplied evidence.
Technical view
The plugin’s plugin_toolbar_comparte settings page lacks nonce validation, creating CSRF exposure that can lead to stored cross-site scripting through settings changes. The CVSS 3.1 score is 8.8, with network attack vector, low complexity, no attacker privileges, and required user interaction.
Likely exposure
Exposure is limited to WordPress sites running ToolBar to Share up to and including version 2.0. Sites without this plugin, or without affected versions, are not indicated as exposed by the supplied sources.
Exploitation context
The sources do not show CISA KEV listing or active exploitation. Abuse requires tricking a logged-in site administrator into performing an action that submits a forged request.
Researcher notes
The key issue is missing nonce validation on the plugin settings page, enabling CSRF that can become stored XSS. Evidence does not identify a specific patched version in the supplied bundle, so remediation should be tied to vendor guidance or plugin removal.
Mitigation direction
- Identify any WordPress sites running ToolBar to Share.
- Remove or disable the plugin if it is unused.
- Check vendor or WordPress plugin guidance for a fixed release or replacement.
- Restrict administrator browsing and plugin administration to trusted workflows.
- Monitor affected sites for unexpected script or plugin setting changes.
Validation and detection
- Confirm whether ToolBar to Share is installed on each WordPress site.
- Check installed plugin version against affected versions up to 2.0.
- Review plugin settings for unexpected changes or injected script content.
- Verify whether the settings page uses nonce validation before accepting changes.
- Check WordPress logs and admin activity for suspicious setting updates.
