Summary

The current advisory lists the affected version range as "introduced": "0" (all versions), which incorrectly flags versions of @modelcontextprotocol/sdk that do not contain the vulnerable code.

This PR changes the affected range from >= 0, < 1.25.2 to >= 1.3.0, < 1.25.2.

Evidence

The vulnerable UriTemplate class (specifically the partToRegExp() method containing the ReDoS-prone regex ([^/]+(?:,[^/]+)*)) was first introduced in commit 7f0cf730 ("URI Template parser and matcher"), which first shipped in version 1.3.0. The file src/shared/uriTemplate.ts does not exist in any earlier version.

Verified not affected (file src/shared/uriTemplate.ts absent, no URI template matching logic):

  • 0.0.23
  • 0.7.0
  • 1.0.3
  • 1.2.0

Verified affected (file present, vulnerable regex confirmed with ReDoS PoC):

  • 1.10.0
  • 1.25.1

Summary
The current advisory lists the affected version range as "introduced": "0" (all versions), which incorrectly flags versions of @modelcontextprotocol/sdk that do not contain the vulnerable code.
This PR changes the affected range from >= 0, < 1.25.2 to >= 1.3.0, < 1.25.2.
Evidence
The vulnerable UriTemplate class (specifically the partToRegExp() method containing the ReDoS-prone regex ([^/]+(?:,[^/]+)*)) was first introduced in commit 7f0cf730 ("URI Template parser and matcher"), which first shipped in version 1.3.0. The file src/shared/uriTemplate.ts does not exist in any earlier version.
Verified not affected (file src/shared/uriTemplate.ts absent, no URI template matching logic):
  • 0.0.23
  • 0.7.0
  • 1.0.3
  • 1.2.0
Verified affected (file present, vulnerable regex confirmed with ReDoS PoC):
  • 1.10.0
  • 1.25.1
