Security readout for executives and security teams
Plain-English summary
A vulnerable Yes/No Chart WordPress plugin version could let a logged-in user with contributor-level access abuse a chart shortcode parameter to query the site database indirectly. This is not confirmed as actively exploited in the provided sources, but SQL injection can expose sensitive content or support broader compromise.
Executive priority
Treat this as a targeted WordPress plugin risk. Prioritize updates where contributor access is broad, shared, or exposed through compromised accounts. It is less urgent than an unauthenticated internet-facing flaw, but still warrants prompt remediation because SQL injection affects database confidentiality.
Technical view
CVE-2021-24360 is a CWE-89 blind SQL injection in the Yes/No Chart WordPress plugin before 1.0.12. The plugin failed to sanitize the sid shortcode parameter before using it in a SQL statement. The cited description limits exploitation to authenticated users with contributor privileges or higher.
Likely exposure
Exposure is limited to WordPress sites running Yes/No Chart before 1.0.12 where untrusted or compromised contributor-level accounts can create or modify shortcode content.
Exploitation context
The provided sources do not show CISA KEV listing, active exploitation, public exploitation volume, or CVSS scoring. The known attacker requirement is authenticated contributor-level access or higher.
Researcher notes
The source bundle identifies the vulnerable input and privilege threshold but does not provide CVSS, detailed exploit telemetry, or vendor remediation notes beyond the before-1.0.12 version boundary. Avoid assuming unauthenticated reachability or confirmed exploitation.
Mitigation direction
- Upgrade Yes/No Chart to version 1.0.12 or later.
- Disable or remove the plugin if it is not needed.
- Restrict contributor-level access to trusted users only.
- Review vendor or WPScan guidance before applying compensating controls.
- Audit recently changed posts or pages containing Yes/No Chart shortcodes.
Validation and detection
- Inventory WordPress sites for the Yes/No Chart plugin.
- Confirm installed plugin versions are 1.0.12 or later.
- Review accounts with contributor, author, editor, or admin privileges.
- Check recent content changes involving Yes/No Chart shortcodes.
- Review logs for unusual database errors or plugin-related anomalies.
