CVE-2025-32422: AutoGPT has a DoS vulnerability in FileStoreBlock with StepThroughItemsBlock
AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Prior to 0.6.63, `StepThroughItemsBlock` can iterate all the contents in a list and send them to `FileStoreBlock` for downloading one by one. Although `FileStoreBlock` has access time limits for downloading files, `StepThroughItemsBlock` can be used to slowly iterate and download relatively small files (e.g., 100M) multiple times. `StepThroughItemsBlock` does not limit the number of loops. In addition, `FileStoreBlock` does not limit the amount of disk space consumed in the current working directory. When a malicious user chooses to download too many videos, the disk space will eventually run out, causing a DoS. Version 0.6.63 patches the issue.
Security readout for executives and security teams
Plain-English summary
AutoGPT versions before 0.6.63 can be abused to fill server disk space and disrupt service. A workflow can repeatedly download many files through built-in blocks until storage is exhausted. The issue is a denial-of-service risk, not a data theft or code execution issue based on the provided sources.
Executive priority
Prioritize remediation for internet-accessible or multi-user AutoGPT deployments. The business risk is service outage from disk exhaustion. Upgrade planning should be near-term, especially where users outside the core admin team can run workflows.
Technical view
CVE-2025-32422 is a CWE-400 resource consumption flaw in AutoGPT. StepThroughItemsBlock can loop through many items without a loop limit and feed downloads to FileStoreBlock. FileStoreBlock has download time limits but no working-directory disk consumption limit. This can exhaust disk space and cause denial of service. Fixed in 0.6.63.
Likely exposure
Organizations running AutoGPT before 0.6.63 are potentially exposed, especially where untrusted users can create or run workflows using StepThroughItemsBlock and FileStoreBlock. Exposure depends on deployment access controls and available disk capacity.
Exploitation context
The CVSS vector indicates network access, low complexity, no privileges, and no user interaction. The provided sources do not state active exploitation, and the CVE is not listed as KEV in the supplied bundle.
Researcher notes
The advisory attributes the flaw to missing loop limits in StepThroughItemsBlock and missing disk consumption limits in FileStoreBlock. Impact is availability only in the provided CVSS data. No public exploit details or active exploitation evidence are included in the supplied sources.
Mitigation direction
Upgrade AutoGPT to version 0.6.63 or later.
Restrict who can create or run AutoGPT workflows.
Review workflows using StepThroughItemsBlock and FileStoreBlock together.
Monitor disk usage on AutoGPT hosts.
Check the GitHub advisory for any updated vendor guidance.
Validation and detection
Inventory AutoGPT deployments and confirm running versions.
Identify any instances below version 0.6.63.
Review access controls for workflow creation and execution.
Check logs and storage metrics for abnormal download-driven disk growth.
Confirm disk monitoring and alerting exist for AutoGPT working directories.
