GitHub Vulnerability Alerts

CVE-2026-0621

Impact

A ReDoS vulnerability in the UriTemplate class allows attackers to cause denial of service. The partToRegExp() function generates a regex pattern with nested quantifiers (([^/]+(?:,[^/]+)*)) for exploded template variables (e.g., {/id*}, {?tags*}), causing catastrophic backtracking on malicious input.

Who is affected: MCP servers that register resource templates with exploded array patterns and accept requests from untrusted clients.

Attack result: An attacker sends a crafted URI via resources/read request, causing 100% CPU utilization, server hang/crash, and denial of service for all clients.

Affected Versions

All versions of @modelcontextprotocol/sdk prior to the patched release.

Patches

v1.25.2 contains b392f02ffcf37c088dbd114fedf25026ec3913d3 the fix modifies the regex pattern to prevent backtracking.

Workarounds

Avoid using exploded patterns ({/id*}, {?tags*}) in resource templates
Implement request timeouts and rate limiting
Validate URIs before processing to reject suspicious patterns

Check changeset necessity

Status:

NOT REQUIRED

Reason:

The only change is a dependency bump of @modelcontextprotocol/sdk (1.24.0 → 1.25.2) in frontend/internal-packages/mcp-server.
mcp-server is not one of the target release packages that require changesets: @liam-hq/cli, @liam-hq/erd-core, @liam-hq/schema, @liam-hq/ui.
No user-facing code or dependencies in the target packages were modified; no API, feature, or behavioral changes to published packages.
Although it’s a security fix, its impact is limited to the internal mcp-server and does not affect released packages’ public surface.
