How to Fix GHSA-j5qp-p44g-2m49

To remediate this vulnerability, upgrade all affected @asymmetric-effort/specifyjs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@asymmetric-effort/specifyjs fixed: 0.2.136 
npm install @asymmetric-effort/specifyjs@0.2.136
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @asymmetric-effort/specifyjs

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-j5qp-p44g-2m49, inspect your project dependencies using npm:

npm ls @asymmetric-effort/specifyjs

Analyze the terminal output to locate any version of @asymmetric-effort/specifyjs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.136), your application is affected.

Note: The npm ls @asymmetric-effort/specifyjs command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In @asymmetric-effort/specifyjs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Finding **Location**: `core/src/shared/secure-fetch.ts` `assertSecureUrl` validated only the initial request URL. The `fetch()` API follows redirects by default (up to 20 hops). A request to a valid `https://` URL could redirect to `http://internal-service/` or other unvalidated destinations. ## Status **Fixed in v0.2.136** — `secureFetch` now defaults to `redirect: 'error'` which rejects any redirect. Callers can override with `{ redirect: 'follow' }` if they trust the target.
