Regex DoS Vulnerability in AutoGPT Code Extraction Block

Publication date: 2026-02-10

Last updated on: 2026-02-17

Assigner: GitHub, Inc.

Description
AutoGPT is a platform that allows users to create, deploy, and manage continuous artificial intelligence agents that automate complex workflows. The autogpt before 0.6.32 is vulnerable to Regular Expression Denial of Service due to the use of regex at Code Extraction Block. The two Regex are used containing the corresponding dangerous patterns \s+[\s\S]*? and \s+(.*?). They share a common characteristic — the combination of two adjacent quantifiers that can match the same space character (\s). As a result, an attacker can supply a long sequence of space characters to trigger excessive regex backtracking, potentially leading to a Denial of Service (DoS). This vulnerability is fixed in 0.6.32.

Executive Summary

This vulnerability exists in AutoGPT versions before 0.6.32 and is a Regular Expression Denial of Service (ReDoS) issue. It occurs because two regular expressions used in the Code Extraction Block contain dangerous patterns with adjacent quantifiers that can match the same space character. An attacker can exploit this by supplying a long sequence of space characters, causing excessive backtracking in the regex engine, which can lead to a Denial of Service (DoS).

Impact Analysis

The vulnerability can be exploited to cause a Denial of Service (DoS) by making the application spend excessive time processing crafted input with many space characters. This can lead to service unavailability or degraded performance, impacting the reliability and availability of systems using vulnerable versions of AutoGPT.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade AutoGPT to version 0.6.32 or later, where the Regular Expression Denial of Service issue has been fixed.
