{"id":"CVE-2026-33235","state":"PUBLISHED","title":"AutoGPT: Denial of Service (DoS) via Resource Exhaustion in text templating features","description":"AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. In versions prior to 0.6.52, the Fill Text Template block is vulnerable to a Denial of Service (DoS) attack. While the backend implements a SandboxedEnvironment to prevent unauthorized attribute access (e.g., blocking __class__), it fails to limit the computational complexity or execution time of the expressions. An attacker can input computationally expensive Python/Jinja2 expressions that consume the server's CPU and memory, leading to a complete system hang or crash. In multi-tenant or self-hosted environments, this results in a complete service outage and \"noisy neighbor\" effects that require manual administrative intervention to recover. This issue has been fixed in version 0.6.52.","publishedAt":"2026-06-24T20:52:00.388Z","updatedAt":"2026-06-25T15:42:19.793Z","severity":{"score":7.7,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["Significant-Gravitas AutoGPT"],"affected":[{"vendor":"Significant-Gravitas","product":"AutoGPT","versions":[{"version":">= 0.1.0, < 0.6.52","status":"affected"}]}],"references":["https://github.com/Significant-Gravitas/AutoGPT/security/advisories/GHSA-ppw9-h7rv-gwq9","https://github.com/Significant-Gravitas/AutoGPT/releases/tag/autogpt-platform-beta-v0.6.52"],"weaknesses":["CWE-400"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33235.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33235","state":"PUBLISHED","datePublished":"2026-06-24T20:52:00.388Z","dateUpdated":"2026-06-25T15:42:19.793Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-18T02:42:27.508Z"},"containers":{"cna":{"title":"AutoGPT: Denial of Service (DoS) via Resource Exhaustion in text templating features","descriptions":[{"lang":"en","value":"AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents.
