Retool < 3.88.0 XSS via /api/imageProxy SVG Proxying

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
