CVE-2026-60088: PraisonAI: Project custom command templates can read outside-workspace files into model prompts

PraisonAI’s new file-based custom command feature auto-discovers project commands from .praisonai/commands/*.md. When a user runs praisonai run --command <name> inside a repository, the command body is interpolated before it is sent as the model prompt.

The interpolation code expands @path references by reading files relative to the current working directory, but it does not canonicalize the target or require it to stay inside the project. A repository-controlled command can therefore include @../outside_secret.txt or an absolute path and cause PraisonAI to copy process-readable files outside the workspace into the prompt.

This is a confidentiality issue in the untrusted-repository workflow: a project can make a normal-looking custom command exfiltrate local files to whichever model/provider receives the generated prompt.
