bolt/core is vulnerable to Open Redirect
50
Medium Risk
This Affects:
bolt/coreTL;DR
The backend bulk-operations controller builds its post-action redirect directly from the incoming Referer request header without validating if the target is a local URL. A backend user can submit a bulk status change or delete from an externally hosted page and be redirected to an arbitrary domain after the operation completes. The fix routes the redirect through Symfony's HTTP utilities so only validated targets are used.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you have authenticated backend users who can trigger a bulk content operation.
