Identified and documented a HIGH severity Denial of Service (DoS) vulnerability in the SysCore backend where docker.wait_container lacks a timeout.
Attackers could send infinite loop code (e.g. while True: pass) to the /api/execute endpoint, causing the server thread to hang indefinitely and exhaust resources.

The issue has been fully documented in SECURITY_ISSUE.md and the systemic cause recorded in the .jules/sentinel.md journal. No application code was modified as per the instructions.

📝 Walkthrough

Walkthrough

This pull request updates security documentation by shifting focus from an arbitrary file write vulnerability to a denial of service vulnerability caused by missing timeout in Docker container execution. The documentation reorganizes existing content and replaces vulnerability details, impact assessment, reproduction steps, and remediation guidance across two markdown files.

Changes

Cohort / File(s) Summary
Security Documentation Updates
.jules/sentinel.md, SECURITY_ISSUE.md
Reorganizes vulnerability documentation and shifts vulnerability focus from arbitrary file write (via unsanitized filenames in syscore/src/server/aether.rs) to denial of service (via missing timeout in syscore/src/docker/manager.rs). Updates impact assessment, reproduction steps, and remediation guidance to include timeout implementation using tokio::time::timeout.

⚠️ Potential issue | 🟡 Minor

Update the referenced source line to the current location.

The snippet points to syscore/src/docker/manager.rs:96, but the vulnerable wait call is documented elsewhere at syscore/src/docker/manager.rs:127-136 (call at Line 129). Please correct the line reference to keep triage accurate.
