AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Prior to 0.6.63, ScreenshotWebPageBlock will store the captured screenshots in a temporary directory. "StepThroughItemsBlock" can be used to iterate "ScreenshotWebPageBlock" multiple times. "StepThroughItemsBlock" does not limit the number of loops. In addition, "ScreenshotWebPageBlock" does not limit the amount of disk space consumed in the current working directory. When a malicious user chooses to screen shot many web pages, the disk space will eventually run out, causing a DoS. Version 0.6.63 patches the issue.
