Resolves npm audit security vulnerabilities and updates dependencies to their latest compatible versions for the v1.x release branch.

This is the backport of #1381

Motivation and Context

Running npm audit on the v1.x branch was reporting multiple high-severity security vulnerabilities:

  1. Hono JWT vulnerabilities (GHSA-3vhc-576x-3qv4, GHSA-f67f-6cw9-8mq4):

    • JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)
    • JWT Algorithm Confusion via Unsafe Default (HS256) allowing token forgery and auth bypass
    • Affects hono <4.11.4 (transitive dependency via @hono/node-server)
    • Fixed by bumping @hono/node-server to ^1.19.9 and adding hono ^4.11.4 as a direct dependency

  2. qs package vulnerability:

    • Security issue in transitive dependency qs
    • Fixed by adding npm overrides to force qs@6.14.1

This PR addresses these vulnerabilities by:

  • Bumping @hono/node-server to ^1.19.9
  • Adding hono ^4.11.4 as a direct dependency (resolves Hono JWT vulnerabilities)
  • Adding npm overrides for qs@6.14.1 (resolves qs vulnerability)
  • Bumping other dependencies to latest compatible versions
  • Updating test assertions to match updated library error messages

How Has This Been Tested?

  • ✅ npm audit reports 0 vulnerabilities after this change
  • ✅ All existing tests pass (npm test - all 1497 tests pass)
  • ✅ npm run build completes successfully
  • ✅ Test assertions updated to match jose library's updated error message format

Breaking Changes

None. This is a patch release with security fixes and dependency updates only.

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update

Checklist

  • I have read the MCP Documentation
  • My code follows the repository's style guidelines
  • New and existing tests pass locally
  • I have added appropriate error handling
  • I have added or updated documentation as needed

Additional context

Security fixes:

  • Hono JWT vulnerabilities (GHSA-3vhc-576x-3qv4, GHSA-f67f-6cw9-8mq4):
    • @hono/node-server (^1.19.7 → ^1.19.9)
    • hono (added as direct dependency at ^4.11.4 to ensure secure version)
  • qs vulnerability: npm overrides for qs@6.14.1

Dependency updates:

  • express (^5.0.1 → ^5.2.1)
  • express-rate-limit (^7.5.0 → ^8.2.1)
  • jose (^6.1.1 → ^6.1.3)
  • zod-to-json-schema (^3.23.2 → ^3.25.1)

Test fixes:

  • Updated error message regex in packages/client/test/client/auth-extensions.test.ts to match jose library's updated error output (changed from /Invalid character/ to /cannot be part of a valid base64/)

Implementation notes:

  • hono was added as a direct dependency instead of using npm overrides to ensure the secure version (4.11.4) is always installed, even as @hono/node-server updates its transitive dependencies
  • All changes maintain backward compatibility with the v1.x branch

Hi, thank you for this. Since the qs issue is coming from express, and express is updated here, is there a real need for the qs override anymore?

Hi @KKonstantinov 👋🏼, happy to help if I can
yeah, unfortunately the qs version is still the old one from the last release, but I saw they recently pushed a commit to main with the bump. It should be fixed in the next release

  •  Bug fix (non-breaking change which fixes an issue)
  •  New feature (non-breaking change which adds functionality)
  •  Breaking change (fix or feature that would cause existing functionality to change)
  •  Documentation update
Checklist
  •  I have read the MCP Documentation
  •  My code follows the repository's style guidelines
  •  New and existing tests pass locally
  •  I have added appropriate error handling
  •  I have added or updated documentation as needed
Additional context
Security fixes:
  • Hono JWT vulnerabilities (GHSA-3vhc-576x-3qv4, GHSA-f67f-6cw9-8mq4):

    • @hono/node-server (^1.19.7 → ^1.19.9)
    • hono (added as direct dependency at ^4.11.4 to ensure secure version)
  • qs vulnerability: npm overrides for qs@6.14.1
Dependency updates:
  • express (^5.0.1 → ^5.2.1)
  • express-rate-limit (^7.5.0 → ^8.2.1)
  • jose (^6.1.1 → ^6.1.3)
  • zod-to-json-schema (^3.23.2 → ^3.25.1)
Test fixes:
  • Updated error message regex in packages/client/test/client/auth-extensions.test.ts to match jose library's updated error output (changed from /Invalid character/ to /cannot be part of a valid base64/)
Implementation notes:
  • hono was added as a direct dependency instead of using npm overrides to ensure the secure version (4.11.4) is always installed, even as @hono/node-server updates its transitive dependencies
  • All changes maintain backward compatibility with the v1.x branch

Hi, thank you for this. Since the qs issue is coming from express, and express is updated here, is there a real need for the qs override anymore?

Hi @KKonstantinov 👋🏼, happy to help if I can

yeah, unfortunately the qs version is still the old one from the last release, but I saw they recently pushed a commit to main with the bump. It should be fixed in the next release

Resolves npm audit security vulnerabilities and updates dependencies to their latest compatible versions for the v1.x release branch.
This is the backport of #1381
Motivation and Context
Running npm audit on the v1.x branch was reporting multiple high-severity security vulnerabilities:
  1. Hono JWT vulnerabilities (GHSA-3vhc-576x-3qv4, GHSA-f67f-6cw9-8mq4):
    • JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)
    • JWT Algorithm Confusion via Unsafe Default (HS256) allowing token forgery and auth bypass
    • Affects hono <4.11.4 (transitive dependency via @hono/node-server)
    • Fixed by bumping @hono/node-server to ^1.19.9 and adding hono ^4.11.4 as a direct dependency
  2. qs package vulnerability:
    • Security issue in transitive dependency qs
    • Fixed by adding npm overrides to force qs@6.14.1
This PR addresses these vulnerabilities by:
  • Bumping @hono/node-server to ^1.19.9
  • Adding hono ^4.11.4 as a direct dependency (resolves Hono JWT vulnerabilities)
  • Adding npm overrides for qs@6.14.1 (resolves qs vulnerability)
  • Bumping other dependencies to latest compatible versions
  • Updating test assertions to match updated library error messages
How Has This Been Tested?
  • ✅ npm audit reports 0 vulnerabilities after this change
  • ✅ All existing tests pass (npm test - all 1497 tests pass)
  • ✅ npm run build completes successfully
  • ✅ Test assertions updated to match jose library's updated error message format
Breaking Changes
None. This is a patch release with security fixes and dependency updates only.
Types of changes
  •  Bug fix (non-breaking change which fixes an issue)
  •  New feature (non-breaking change which adds functionality)
  •  Breaking change (fix or feature that would cause existing functionality to change)
  •  Documentation update
Checklist

Hi @KKonstantinov 👋🏼, happy to help if I can

yeah, unfortunately the qs version is still the old one from the last release, but I saw they recently pushed a commit to main with the bump. It should be fixed in the next release

Resolves npm audit security vulnerabilities and updates dependencies to their latest compatible versions for the v1.x release branch.
This is the backport of #1381
Motivation and Context
Running npm audit on the v1.x branch was reporting multiple high-severity security vulnerabilities:
  1. Hono JWT vulnerabilities (GHSA-3vhc-576x-3qv4, GHSA-f67f-6cw9-8mq4):
    • JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)
    • JWT Algorithm Confusion via Unsafe Default (HS256) allowing token forgery and auth bypass
    • Affects hono <4.11.4 (transitive dependency via @hono/node-server)
    • Fixed by bumping @hono/node-server to ^1.19.9 and adding hono ^4.11.4 as a direct dependency
  2. qs package vulnerability:
    • Security issue in transitive dependency qs
    • Fixed by adding npm overrides to force qs@6.14.1
This PR addresses these vulnerabilities by:
  • Bumping @hono/node-server to ^1.19.9
  • Adding hono ^4.11.4 as a direct dependency (resolves Hono JWT vulnerabilities)
  • Adding npm overrides for qs@6.14.1 (resolves qs vulnerability)
  • Bumping other dependencies to latest compatible versions
  • Updating test assertions to match updated library error messages
How Has This Been Tested?
  • ✅ npm audit reports 0 vulnerabilities after this change
  • ✅ All existing tests pass (npm test - all 1497 tests pass)
  • ✅ npm run build completes successfully
  • ✅ Test assertions updated to match jose library's updated error message format
Breaking Changes
None. This is a patch release with security fixes and dependency updates only.
Types of changes
  •  Bug fix (non-breaking change which fixes an issue)
  •  New feature (non-breaking change which adds functionality)
  •  Breaking change (fix or feature that would cause existing functionality to change)
  •  Documentation update
Checklist
  •  I have read the MCP Documentation
  •  My code follows the repository's style guidelines
  •  New and existing tests pass locally
  •  I have added appropriate error handling
  •  I have added or updated documentation as needed
Additional context
Security fixes:
  • Hono JWT vulnerabilities (GHSA-3vhc-576x-3qv4, GHSA-f67f-6cw9-8mq4):

    • @hono/node-server (^1.19.7 → ^1.19.9)
    • hono (added as direct dependency at ^4.11.4 to ensure secure version)
  • qs vulnerability: npm overrides for qs@6.14.1
Dependency updates:
  • express (^5.0.1 → ^5.2.1)
  • express-rate-limit (^7.5.0 → ^8.2.1)
  • jose (^6.1.1 → ^6.1.3)
  • zod-to-json-schema (^3.23.2 → ^3.25.1)
Test fixes:
  • Updated error message regex in packages/client/test/client/auth-extensions.test.ts to match jose library's updated error output (changed from /Invalid character/ to /cannot be part of a valid base64/)
Implementation notes:
  • hono was added as a direct dependency instead of using npm overrides to ensure the secure version (4.11.4) is always installed, even as @hono/node-server updates its transitive dependencies
  • All changes maintain backward compatibility with the v1.x branch
