## What is CVE-2026-55237?

AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Versions prior to 0.6.62 have a DOM-based Cross-Site Scripting (XSS) vulnerability in AutoGPT's signup page. The application improperly trusts a URL parameter (`next`), which is passed to `router.push`. An attacker can craft a malicious link that, when opened by an authenticated user, performs a client-side redirect and executes arbitrary JavaScript in the context of their browser. This could lead to credential theft, internal network pivoting, and unauthorized actions performed on behalf of the victim. Version 0.6.62 patches the issue.

The record classifies CVE-2026-55237 under weakness classes [CWE-87](https://cwe.mitre.org/data/definitions/87.html), [CWE-601](https://intel.threadlinqs.com/cwe/CWE-601).
