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 was 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 accepts user inputs for smtp_server and smtp_port, which are then used directly in Python's smtplib.SMTP() to establish TCP connections without validating the IP address. This bypasses the platform's hardened SSRF protections that normally block connections to private, loopback, link-local, and cloud metadata addresses. As a result, an authenticated user can leverage this to conduct internal network port scanning and fingerprint services by reading TCP banners returned in exception messages. The vulnerability is classified as CWE-918 and has a CVSS v3.1 base score of 5.0 (medium severity). It was fixed in AutoGPT version 0.6.52.
Potential Impact
An authenticated user on a shared AutoGPT deployment can exploit this SSRF vulnerability to perform internal network port scanning and service fingerprinting. This could potentially reveal information about internal services and network topology. The vulnerability does not directly allow data confidentiality or integrity compromise but leaks service banners via exception messages. There are no known exploits in the wild as of the published date.
Mitigation Recommendations
This vulnerability has been fixed in AutoGPT version 0.6.52. Users should upgrade to version 0.6.52 or later to remediate this issue. Since the vendor advisory does not provide an official patch link or alternative mitigations, upgrading to the fixed version is the recommended action. Patch status is confirmed by the version fix note in the description.
