docs(security): Report broken auth vulnerability in aether upload handler

[Vaiditya2207]

Documented a Broken Auth vulnerability in syscore/src/server/aether.rs where upload_handler falls back to a weak default credential if AETHER_UPLOAD_KEY is not set.

Added findings to SECURITY_ISSUE.md and .jules/sentinel.md. No code was modified.

📝 Walkthrough

Walkthrough

Two documentation files are updated to record security findings in the Aether upload handler: SECURITY_ISSUE.md gains a new critical advisory for the hardcoded AETHER_UPLOAD_KEY fallback credential, and .jules/sentinel.md gains dated audit entries for both that broken-auth issue and the existing path-injection risk.

Changes

Security Audit Documentation

Layer / File(s)	Summary
Broken auth advisory and sentinel entries SECURITY_ISSUE.md, .jules/sentinel.md	SECURITY_ISSUE.md adds a 36-line critical advisory for the update_me_please fallback credential in upload_handler, covering impact, reproduction steps, remediation, and OWASP/CWE references. .jules/sentinel.md adds a new dated entry for the broken-auth pattern and an auditor note on the existing PathBuf::join path-injection entry, both directing reviewers to fix insecure defaults.

Possibly related issues

• CRITICAL Injection: Arbitrary File Write via Path Traversal in Aether Upload API #63: The PR's new advisory and sentinel entries directly document the same two vulnerabilities tracked in that issue — the update_me_please hardcoded fallback at line 140 and the unsanitized PathBuf::join filename handling at lines 191–192 of syscore/src/server/aether.rs.

🐇 A rabbit hopped in with a quill and a frown,
"That update_me_please must be written down!
A fallback credential? That just won't do —
And paths joined unsanitized? Yikes, that too!"
So the docs grew longer, the warnings grew clear,
Now every auditor knows what to fear. 🔐
