SCA: security update for @actual-app/sync-server (GHSA-m62c-5q34-f3cf)

high Tenable Self-Hosted Container Security Plugin ID 473730

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Actual is a local-first personal finance tool. Prior to 26.7.0, Actual Sync Server's CORS proxy is
 intended to let authenticated users fetch resources only from repositories listed in the official plugin
 allowlist. When `ACTUAL_GITHUB_TOKEN` is configured, the proxy automatically attaches the server's GitHub
 token to GitHub requests. The GitHub API allowlist check uses a raw `startsWith()` prefix test for
 `/repos/{owner}/{repo}` without requiring a path boundary after the repository name. If an allowlisted
 public plugin repository is `https://github.com/acme/plugin`, the proxy also accepts GitHub API URLs.
 Those URLs are outside the allowlisted repository but still pass because their API path starts with
 `/repos/acme/plugin`. The proxy then forwards the request with the server's `ACTUAL_GITHUB_TOKEN`,
 allowing any authenticated Actual user to read private GitHub resources reachable by that token. Version
 26.7.0 fixes the issue. (CVE-2026-57449)

Solution

Update the @actual-app/sync-server library and its related packages to version 26.7.0 or later.
