Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, a collection that allows downloadable SVG uploads can store a malicious SVG that bypasses sanitization and executes attacker-controlled JavaScript when a user downloads and opens the SVG. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

 https://vulnerability.circl.lu/vuln/ghsa-2pwp-2369-8fg3 GHSA-2pwp-2369-8fg3 — Payload: Bypassed sanitization of user uploaded SVGs 2026-10-08T09:39:30.116465+00:00

Affected: npm: payload

## Impact

A malicious SVG file upload could bypass sanitization, be stored, and execute attacker-controlled JavaScript (XSS) after a user downloads it and opens it.

**You are affected if:**

- You have a collection configured to upload and allow SVG files which can then be downloaded by users.

## Patches

The fix validates SVG content on every upload path and hardens SVG/XML delivery so stored SVGs cannot frame attacker content.

Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.

## Workarounds

Disallow SVG uploads, or serve uploaded SVGs as downloads with Content-Disposition: attachment and a strict CSP. These mitigations reduce exposure but do not replace upgrading when the patched release is available.
