CVE-2026-55237: CWE-87: Improper Neutralization of Alternate XSS Syntax in Significant-Gravitas AutoGPT
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.
AI Analysis
Technical Summary
CVE-2026-55237 is a DOM-based XSS vulnerability in Significant-Gravitas AutoGPT affecting versions before 0.6.62. The vulnerability stems from improper neutralization of alternate XSS syntax (CWE-87) and open redirect behavior (CWE-601) via the 'next' URL parameter on the signup page. This parameter is passed directly to router.push, enabling client-side redirects and arbitrary script execution in the victim's browser context. The vulnerability has a CVSS 3.1 score of 8.8, indicating high severity. The issue is fixed in version 0.6.62.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of an authenticated user's browser session. This can lead to credential theft, unauthorized actions performed on behalf of the victim, and potential internal network pivoting. The vulnerability affects confidentiality, integrity, and availability as indicated by the CVSS vector (C:H/I:L/A:L).
Mitigation Recommendations
Upgrade AutoGPT to version 0.6.62 or later, where this vulnerability is patched. No other official remediation or temporary fixes are documented. Until patched, avoid clicking on untrusted links that include the 'next' parameter in the URL on the signup page.
