Summary
In OpenPanel through 2.3.0, the data importer fetches a caller-supplied URL with plain fetch instead of the project's existing SSRF guard. An authenticated organization member can make the server connect to any address reachable from it, and the resulting HTTP status is persisted as an error message, providing a scanning oracle for internal hosts, ports and paths.
Risk Assessment
SSRF vulnerability may allow an attacker to access internal network resources and inject data into analytics, potentially leading to confidentiality and integrity breaches.
Recommendation
Update OpenPanel to a patched version and ensure the data importer uses a secure URL fetching mechanism with SSRF protection.
Other vulnerabilities in OpenPanel
See all- CVE-2026-116819High
OpenPanel before 3.0.0 contains an information disclosure vulnerability that allows read-level project members to obtain plaintext integration secrets because the notification.rules query skips redactIntegration. Attackers can call the notification.rules tRPC query to retrieve Slack bot tokens, webhook URLs, and authorization headers for use against external systems.
- CVE-2026-116818High
OpenPanel before 3.0.0 contains an unauthenticated ClickHouse SQL injection vulnerability that allows remote attackers to inject SQL through the projectId parameter of the /live/visitors/:projectId WebSocket, which lacks session and project-access checks. Attackers can use UNION or boolean count oracles to read other tenants' events and profiles, and project members can similarly inject via the cohort.preview timeframe values.
- CVE-2026-116817Medium
OpenPanel before 3.0.0 contains a missing authentication vulnerability that allows unauthenticated attackers to access the Bull Board dashboard served on the worker HTTP port. Attackers can query /api/queues and call mutating Bull Board APIs to add, retry, or clean jobs and read queue data, metrics, and datastore health.
- CVE-2026-116815Medium
OpenPanel before 3.0.0 contains an improper escaping vulnerability in sankey.service.ts that allows authenticated project members to break ClickHouse string literals by supplying backslashes in event names. Attackers with read access can submit crafted events[].name values to the chart.sankey procedure, causing ClickHouse parse errors that disable the project's Sankey chart endpoint.
- CVE-2026-116814Medium
OpenPanel before 3.0.0 contains an information exposure vulnerability that writes database connection URLs and email template data to standard output logs. Users with log access can obtain database credentials from migration startup logs and password-reset tokens logged when SMTP_HOST and RESEND_API_KEY are unset.
- CVE-2026-116813Medium
OpenPanel before 3.0.0 contains an SQL injection vulnerability in ConversionService.getConversion that allows project-read members and share-link holders to inject ClickHouse SQL through unescaped event names and dates. Attackers can break out of string literals in series names or startDate/endDate values with OR 1=1 to neutralize project_id scoping and read other tenants' analytics data.
- CVE-2026-116812Medium
OpenPanel before 3.0.0 contains an SQL injection vulnerability in profileColumnAccess in cohort.service.ts that allows project-read members to inject SQL by supplying unescaped profile filter column names. Attackers can submit a cohort.preview filter whose name contains a subquery spliced into argMax, cityHash64, or comparison clauses to read other tenants' ClickHouse data.
- CVE-2026-116811High
OpenPanel before 3.0.0 contains a sandbox escape vulnerability in the js-runtime validator that allows a project member to bypass the AST allowlist by aliasing the Function constructor. Attackers with write access can read payload.constructor.constructor into a local and call it to run arbitrary code in the worker process.
- CVE-2026-116810Medium
OpenPanel before 3.0.0 contains a missing authorization vulnerability that allows unauthenticated attackers to read any project's annotations by calling the public reference.getChartReferences tRPC procedure. Attackers can send requests with guessable slug-based project IDs to dump cross-tenant annotation titles, descriptions, and dates such as release notes and deploy markers.
- CVE-2026-116809Medium
OpenPanel before 3.0.0 contains a missing authorization vulnerability in the event.bots tRPC procedure that allows unauthenticated attackers to read bot events by only checking shareOverview row existence. Attackers can send anonymous requests with a projectId to retrieve bot-event names, types, and paths for private or password-protected projects, revealing internal routes.
Original NVD description (English source)
In OpenPanel through 2.3.0, 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 project_access 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.
