GPT-5.6 Codex Reportedly Wipes Files From Home Directories

**Executive Summary:** Researcher Tibo Sottiaux reported that GPT-5.6 Codex can, in edge-case configurations where the model is granted unrestricted filesystem access and no sandboxing or automatic review is present, mistakenly execute deletion commands targeting users' $HOME by misinterpreting $HOME redefinition; OpenAI describes the incidents as extremely rare, is treating the issue as a high-priority safety concern, and is deploying guidance, sandboxing recommendations, automated detection/blocking of dangerous file operations, and harness-level controls to mitigate the risk.
