chore(deps): update dependency undici to v7.18.2 [security]

[renovate]

This PR contains the following updates:

Package	Change	Age	Confidence
undici (source)	7.16.0 → 7.18.2

GitHub Vulnerability Alerts

CVE-2026-22036

Impact

The fetch() API supports chained HTTP encoding algorithms for response content according to RFC 9110 (e.g., Content-Encoding: gzip, br). This is also supported by the undici decompress interceptor.

However, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation.

Patches

Upgrade to 7.18.2 or 6.23.0.

Workarounds

It is possible to apply an undici interceptor and filter long Content-Encoding sequences manually.

Check changeset necessity

Status: NOT REQUIRED

Reason:

• Only the root pnpm overrides and lockfile were updated to pin undici from 7.16.0 to 7.18.2; no package code or manifests for target packages (@liam-hq/cli, @liam-hq/erd-core, @liam-hq/schema, @liam-hq/ui) were changed.
• This is a dependency bump for security hardening with no user-facing feature, API, or behavior changes in our published packages.
• Lockfile and tooling/override adjustments do not affect consumers directly and are considered non-user-facing per the guide.

Changeset (copy & paste):

# No changeset required for this PR (dependency override/lockfile only).
