CVE-2026-116548 e4jvikwp CVE debrief

Who should care

Defenders responsible for WordPress installations using the VikRentCar Car Rental Management System plugin, particularly those with versions up to 1.4.10, should assess exposure and prioritize verification and remediation efforts.

Why it matters

The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Stored Cross-Site Scripting, allowing unauthenticated attackers to inject arbitrary web scripts. Defenders should prioritize verifying and updating the plugin, assessing exposure, and implementing compensating controls.

• Unauthenticated attackers can inject arbitrary web scripts
• Scripts execute when a user accesses an injected page
• Potential for Cross-Site Scripting attacks
• Verification of plugin version and exposure is necessary

Technical summary

The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'optionals' parameter in all versions up to, and including, 1.4.10. This is due to insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability has a CVSS score of 7.2 and is considered HIGH severity. Defenders should prioritize verifying and updating the plugin, assessing exposure in their environments, and implementing compensating controls to detect and prevent exploitation.

Defensive priority

Defenders should prioritize verifying and updating the VikRentCar Car Rental Management System plugin to a version beyond 1.4.10, assessing exposure in their environments, and implementing compensating controls to detect and prevent exploitation.

Recommended defensive actions

• Verify and update the VikRentCar Car Rental Management System plugin to a version beyond 1.4.10
• Assess exposure in environments using the vulnerable plugin
• Implement compensating controls to detect and prevent exploitation
• Monitor for suspicious activity related to the plugin
• Review relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
