CVE-2026-33234: CWE-918: Server-Side Request Forgery (SSRF) in Significant-Gravitas AutoGPT
CVE-2026-33234 is a Server-Side Request Forgery (SSRF) vulnerability in Significant-Gravitas AutoGPT versions 0. 1. 0 through 0. 6. 51. The vulnerability arises because the SendEmailBlock accepts user-supplied SMTP server and port inputs and passes them directly to Python's smtplib. SMTP() without IP address validation. This bypasses the platform's usual SSRF protections, allowing an authenticated user on a shared deployment to perform internal network port scanning and service fingerprinting. The issue has been fixed in version 0. 6.
AI Analysis
Technical Summary
AutoGPT is a workflow automation platform for AI agents. In versions 0.1.0 to 0.6.51, the SendEmailBlock component allows authenticated users to specify smtp_server and smtp_port parameters that are passed directly to smtplib.SMTP() without validation. This bypasses the platform's SSRF protections that normally block connections to private, loopback, link-local, and cloud metadata IP ranges. As a result, attackers can perform internal network reconnaissance by reading TCP banners from targeted hosts, which are exposed in error messages visible to the user. The vulnerability is tracked as CWE-918 and has a CVSS 3.1 base score of 5.0 (medium severity). It was fixed in version 0.6.52.
Potential Impact
An authenticated user on a shared AutoGPT deployment can exploit this vulnerability to conduct internal network port scanning and service fingerprinting. This could reveal information about internal services and network topology. The vulnerability does not directly allow data modification or denial of service but leaks internal network details via SMTP connection error messages.
Mitigation Recommendations
This vulnerability is fixed in AutoGPT version 0.6.52. Users should upgrade to version 0.6.52 or later to remediate this issue. Since the product is not a cloud service, remediation requires applying the official fix by upgrading. Patch status is not explicitly confirmed in the vendor advisory, but the fix is stated to be included in version 0.6.52. Until upgraded, restrict authenticated user permissions and avoid running shared deployments where untrusted users can specify SMTP parameters.
