Security readout for executives and security teams
Plain-English summary
CVE-2026-4306 affects the WordPress WP Job Portal plugin. An unauthenticated attacker may be able to manipulate the “radius” parameter to read sensitive database information. For sites using this recruitment plugin, the main business concern is confidentiality of WordPress data, including job portal and user-related records.
Executive priority
Treat as high priority for public WordPress sites using WP Job Portal. The issue can expose sensitive database information without login. Patch or mitigate affected deployments promptly, but do not assume active exploitation from the provided sources.
Technical view
The issue is SQL injection in WP Job Portal through insufficient escaping and query preparation around the user-supplied “radius” parameter. The CVSS 3.1 score is 7.5, network exploitable, low complexity, no privileges or user interaction required, with high confidentiality impact and no stated integrity or availability impact.
Likely exposure
Internet-facing WordPress sites running WP Job Portal versions up to and including 2.4.8 are the relevant exposure. Sites not using this plugin are not affected by the described issue.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. However, the vulnerability is unauthenticated, remotely reachable, and targets a WordPress plugin, which makes timely validation important.
Researcher notes
The source bundle states affected versions up to 2.4.8 and includes a 2.4.8-to-2.4.9 changeset. The structured affected metadata is inconsistent, listing version “0” and default unaffected, so confirm against Wordfence and WordPress plugin repository data.
Mitigation direction
- Identify all WordPress sites using WP Job Portal.
- If running version 2.4.8 or earlier, prioritize update review.
- Check the WordPress plugin repository and vendor guidance for the fixed release.
- Apply the vendor-supported update after normal backup and change control.
- Temporarily restrict or disable exposed job search functionality if immediate updating is impossible.
Validation and detection
- Inventory WP Job Portal plugin versions across WordPress assets.
- Confirm whether any instance is version 2.4.8 or earlier.
- Review web logs for unusual requests involving the radius parameter.
- Check database and application logs for SQL error patterns.
- Verify the installed plugin reflects the vendor-fixed version after remediation.
