CVE-2026-88892: OpenPanel SSRF via Unguarded Importer File URL Fetch
OpenPanel is an analytics platform. In all versions (no patched release available at time of publication), the data importer fetches a caller-supplied URL with plain fetch instead of the project's existing SSRF guard (apps/api/src/utils/safe-fetch.ts). In packages/importer/src/providers/umami.ts, parseRemoteFile calls fetch() on config.fileUrl, which is validated only by z.string().url(), so values such as http://127.0.0.1:9911/ or http://169.254.169.254/latest/meta-data/ are accepted; the shared createFileImportConfig factory gives the plausible provider the same field. An authenticated organization member — including a default 'member' with no projectaccess rows, for whom the intended access-level check is skipped because getProjectAccess returns boolean true rather than a level object — can therefore make the server connect to any address reachable from it. The resulting HTTP status and status text are persisted as Import.errorMessage and returned by import.get to the same user, providing a scanning oracle for internal hosts, ports and paths; if an internal response parses as Umami CSV, its rows are ingested as events and become readable in the attacker's analytics views.

Frequently Asked Questions
Who can exploit this issue?
An authenticated organization member can exploit it, including a default member with no project_access rows. The intended access-level check is skipped in that case because getProjectAccess returns boolean true rather than an access-level object.
What does an attacker need to provide?
The attacker needs access to the data importer and a caller-controlled fileUrl. The field is only checked as a URL, so it accepts URLs targeting loopback or link-local addresses as well as other addresses reachable by the OpenPanel server.
What can an attacker learn or access through the importer?
The importer stores the fetched HTTP status and status text in Import.errorMessage and returns it through import.get to the requesting user, enabling probing of internal hosts, ports, and paths. If a response parses as Umami CSV, its rows are imported as events and can be viewed in the attacker's analytics views.
Is a fixed release available?
No patched release was available at the time of publication. All versions are described as affected.
