Proposed changes

  • Enhanced censorUrl in @rocket.chat/tools to redact additional sensitive query parameters (token, secret, password, apiKey, api_key, auth_token, authorization, code) in addition to query and access_token.
  • Added case-insensitive matching for query parameters (e.g., TOKEN, Password, ApiKey).
  • Added support for relative URLs (e.g., /api/v1/users.getAvatar?token=secret123, ?token=abc, /path?secret=xyz#profile), preventing new URL() TypeErrors from bypassing redaction and leaking sensitive query tokens to server logs.
  • Added comprehensive unit tests in packages/tools/src/censorUrl.spec.ts covering all new sensitive parameters, relative URLs, hash anchors, and edge cases.
  • Added changeset patch file for @rocket.chat/tools.

Issue(s)

Closes #42026

Steps to test or reproduce

## Summary by CodeRabbit

- **Bug Fixes**
  - Improved URL sanitization by redacting a broader range of sensitive query parameters, including tokens, secrets, passwords, API keys, authorization values, and codes.
  - Sensitive parameter matching is now case-insensitive.
  - Relative, protocol-relative, query-only, and hash-containing URLs are now sanitized correctly while preserving their structure.
  - Usernames and passwords embedded in URLs continue to be protected.
  - URLs that cannot be parsed are handled safely without disrupting the original value.

Walkthrough

censorUrl now redacts more sensitive query parameters, matches parameter names case-insensitively, and sanitizes relative URLs. Tests cover absolute and relative URL cases. A changeset declares a patch release for @rocket.chat/tools.

Changes

censorUrl redaction

Layer / File(s) Summary
Sensitive parameter redaction
packages/tools/src/censorUrl.ts, packages/tools/src/censorUrl.spec.ts
censorUrl redacts credentials and an expanded set of sensitive query parameters with case-insensitive matching. Tests cover the additional parameter names.
Relative URL sanitization
packages/tools/src/censorUrl.ts, packages/tools/src/censorUrl.spec.ts, .changeset/tools-censor-url-sensitive-params.md
Relative URLs are parsed against a fallback base, redacted, and reconstructed without the fallback origin. Tests cover path-based, query-only, hash-containing, and non-sensitive relative URLs. The changeset declares a patch release.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to a527c

This change expands sensitive query-parameter redaction and supports relative URLs, reducing the chance of secrets appearing in logs. No actionable merge-blocking risk remains beyond normal checks and review.
