Who should care

Defenders responsible for Retool instances should assess exposure and prioritize patching to version 3.88.0 or later. This includes operators managing Retool deployments, platform administrators, vulnerability management teams, and security teams responsible for monitoring and protecting these environments. They should review the official advisory and CVE record to validate affected scope, severity, and vendor guidance, and plan vendor-supported updates or

Why it matters

CVE-2024-58394 is a cross-site scripting vulnerability in Retool before version 3.88.0, allowing unauthenticated attackers to execute scripts by proxying malicious SVG files through the /api/imageProxy endpoint. Defenders responsible for Retool instances should assess exposure and prioritize patching to version 3.88.0 or later.

• Execution of arbitrary JavaScript in victims' sessions
• Potential for unauthorized actions on Retool instances
• Need for verification of Content Security Policy implementation
• Priority for patching Retool instances to version 3.88.0 or later

Technical summary

The vulnerability allows unauthenticated attackers to execute scripts by proxying malicious SVG files through the /api/imageProxy endpoint. Attackers can supply an attacker-hosted SVG in the url parameter, which is served from the Retool origin without a Content Security Policy, executing JavaScript in victims' sessions. This issue affects Retool versions before 3.88.0. Defenders should focus on patching to version 3.88.0 or later and verify Content Security Policy implementation for the /api/imageProxy endpoint to mitigate this vulnerability.

Defensive priority

Defenders should prioritize patching Retool instances to version 3.88.0 or later, and verify that Content Security Policy is implemented for the /api/imageProxy endpoint.

Recommended defensive actions

• Patch Retool instances to version 3.88.0 or later
• Verify Content Security Policy implementation for the /api/imageProxy endpoint
• Monitor for suspicious activity on Retool instances
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check 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
