What is CVE-2026-26006?

CVE-2026-26006 is a medium-severity denial of service vulnerability in Significant-Gravitas AutoGPT, published on 10 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official 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.

Weakness: CWE-1333
