Workers execute bash with the current user's permissions in the current writable workspace. Pi Worker is not a sandbox.
Do not post credentials, Pi profiles, provider configuration, prompts, workspace contents, or sensitive logs in public issues. Do not disclose a vulnerability publicly.
Use GitHub private vulnerability reporting. If that channel is unavailable, do not disclose publicly or send secrets elsewhere. Publication requires the private reporting channel to be enabled first.
