CVE-2026-108579

OpenPanel API through 2.3.0 fails to verify client secret cryptographic hash before authorizing revenue events and bot filtering. Attackers with only a public client ID can supply arbitrary dummy secrets to inject forged revenue metrics and bypass bot detection filters.

OpenPanel through 2.3.0 fails to escape property keys in ClickHouse SQL queries, allowing authenticated users to inject boolean SQL terms. Attackers can supply crafted filter names to bypass project isolation and access metrics from other projects.

OpenPanel through 2.3.0 writes Model Context Protocol authentication tokens from URL query parameters to plaintext application logs without redaction. Attackers with access to application stdout or centralized logging systems can capture base64-encoded credentials to replay MCP requests and access project analytics.

OpenPanel through 2.3.0 share lookup procedures fail to validate access controls, allowing unauthenticated callers with a share link to retrieve argon2id password hashes and full report configurations including event names, filters, and breakdown dimensions.

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.

OpenPanel through 2.3.0 fails to enforce read-only project access level on 26 of 29 mutating procedures, allowing read-level members to modify, delete, and publish project data. Attackers with explicit read-only access can delete reports and dashboards, schedule entire projects for deletion, publish private analytics to public share links, and modify alerting rules.

OpenPanel through 2.3.0 has an SQL injection vulnerability in the analytics filter builder that fails to validate profile.* filter column identifiers before interpolating them into ClickHouse WHERE clauses. An authenticated attacker with project-scoped read or root export credentials can inject arbitrary ClickHouse SQL to bypass project isolation and read other organizations' analytics data and profile PII.

OpenPanel before version 2.3.0 contains an insecure direct object reference vulnerability in the report.getLayouts and report.resetLayout tRPC procedures that fail to bind dashboardId to the authorized projectId. Authenticated attackers can supply an arbitrary victim dashboardId with their own projectId to read report layouts and configurations or delete dashboard grid arrangements across tenants.

OpenPanel before version 2.3.0 contains an unauthenticated server-side request forgery vulnerability in the GET /tools/site-checker endpoint that accepts a fully client-controlled URL parameter with no private IP filtering or DNS-rebinding protection.

OpenPanel before 2.3.0 contains a cross-site scripting vulnerability in the unauthenticated favicon proxy endpoint GET /misc/favicon that allows remote attackers to execute scripts by supplying an SVG file URL. Attackers can host malicious SVG files with embedded scripts that execute in the victim's browser on the API origin, enabling same-origin credentialed requests to authenticated endpoints.
