Official description

Retool before 3.88.0 contains a cross-site scripting vulnerability that allows unauthenticated attackers to execute scripts by proxying malicious SVG files through /api/imageProxy. 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. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-10-15.
