📝 Walkthrough

Walkthrough

Two security vulnerabilities are documented across sentinel audit tracking and detailed security advisory: an arbitrary file write risk from unsafe path handling in multipart uploads, and broken authentication from weak default API key fallback when the environment variable is missing.

Changes

Security vulnerability documentation

Layer / File(s)	Summary
Security vulnerability audit and advisory entries .jules/sentinel.md, SECURITY_ISSUE.md	Sentinel audit entries record two vulnerabilities (arbitrary file write via PathBuf::join with user-controlled paths, broken auth via missing env var fallback to known default key), and detailed security issue documentation outlines the broken authentication risk, impact, reproduction steps, remediation, and OWASP reference for the /api/v1/aether upload endpoint.

Possibly related PRs

• Vaiditya2207/OKernel#156: Both PRs update the same Aether multipart upload security advisory for the PathBuf::join absolute-path arbitrary file write issue (and its documentation/auditor note), so the main PR's file-write audit entry is directly related to retrieved PR #156.

Poem

🐰 A sentinel stands guard with watchful eyes,
Two vulns now logged before they grow and rise—
Path joins unwary, keys that fall to weak,
Auditors alerted, fixes all they seek!
