ReleasePort's take
Light signalRelease v5.8.4 of blackboard.py fixes an arbitrary file read/write vulnerability via the --path argument and adds runtime path‑traversal checks while blocking symlink traversal.
Why it matters: Addresses CVE‑style file access risk in CLI; upgrade to v5.8.4 immediately if using `--path`.
Summary
AI summaryFixed arbitrary file read/write vulnerability via --path in blackboard.py (CWE-22).

Full changelog
## Network-AI v5.8.4 — blackboard.py path-traversal fix (CWE-22)
Security
Arbitrary file read/write via --path in blackboard.py (Description-Behavior Mismatch, 96% confidence)
The --path CLI argument was forwarded to SharedBlackboard without any boundary check, allowing an agent or operator to read or write arbitrary local files outside the project directory. This contradicts the documented storage boundary and could be abused to overwrite sensitive project files or operate on attacker-chosen state.
Fix: Added a runtime path-traversal check immediately after argument parsing. args.path.resolve() is tested with relative_to(project_root); any path that escapes the project directory causes the script to exit with a clear error message. Symlink traversal is also blocked because resolve() is called before the comparison. The --path help text and script header comment both document this restriction. SKILL.md capabilities.filesystem updated to reflect the enforcement.
