Summary

Fix high severity security issue in plex-api-spec.yaml.

Vulnerability

Field	Value
ID	V-001
Severity	HIGH
Scanner	multi_agent_ai
Rule	V-001
File	plex-api-spec.yaml:20
Assessment	Likely exploitable
Chain Complexity	2-step

Description: The API specification explicitly documents that the X-Plex-Token authentication credential may be passed as a URL query parameter, exposing tokens in browser history, server logs, proxy logs, and referrer headers.

Evidence

Exploitation scenario: Attackers with access to server logs, browser history, or network monitoring tools can extract X-Plex-Token values from URLs like GET /library/sections?X-Plex-Token=abc123xyz and use them to make.

Scanner confirmation: multi_agent_ai rule V-001 flagged this pattern.

Threat Model Context

This is a private Node.js application (not published to npm). Vulnerabilities affect this application's own runtime only.

Changes

• plex-api-spec.yaml

Behavior Preservation

The change is scoped to 1 file on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.

Automated security fix by OrbisAI Security

Summary by CodeRabbit

• Documentation
  • Updated API authentication guidance to specify that the X-Plex-Token must be provided in the request header.
  • Removed documentation describing the query parameter as an alternative authentication method.

Greptile Summary

The API specification now consistently instructs clients to send X-Plex-Token in the request header. The updated 401 response descriptions match the top-level authentication guidance. The validation checks confirmed that the sole remaining query-parameter reference applies only to an embedded image source URL, not API request authentication.

Confidence Score: 5/5

Safe to merge.

No blocking failure remains.

📝 Walkthrough

Walkthrough

The API specification now documents X-Plex-Token authentication through the request header only. Four 401 response descriptions no longer mention query parameters.

Changes

Authentication documentation

Layer / File(s)	Summary
Header authentication contract plex-api-spec.yaml	The specification removes the query-parameter alternative and updates four 401 responses to state that the token is missing from the header.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to e312f

This localized documentation change directs clients to send authentication tokens in a request header rather than URL query parameters, reducing credential exposure. No actionable merge-blocking risk remains in the current review evidence.

The header holds the token bright
The query path departs tonight
Four error notes now state it plain
The specification stands clear again
Your review is kindly sought, good sir

✅ Review Feedback Addressed

I've automatically addressed 2 review comment(s):

The PR already removed the query-parameter documentation from the main authentication section (line 19), but four 401 response descriptions at lines 16355, 18957, 19345, and 19772 still say "missing from the header or query". This is conflicting guidance that could still lead clients to pass tokens as URL query parameters (exposing them in logs, browser history, etc.). All four occurrences must be updated to say "missing from the header" only.
