Prior to 26.7.0, Actual Sync Server&#8217;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&#8217;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&#8217;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.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Actual is a local-first personal finance tool.
