CVE-2026-88890

OpenPanel share lookup procedures fail to validate access controls and return password hashes and protected report definitions to unauthenticated callers. An attacker with a share link can retrieve argon2id password hashes and full report configurations, including event names, filters, and breakdown dimensions, enabling offline password cracking and business intelligence theft.

OpenPanel's data importer fetches a caller-supplied URL using plain fetch() instead of the project's existing SSRF guard (safe-fetch.ts). Validation is limited to z.string().url(), so addresses such as http://127.0.0.1:9911/ or http://169.254.169.254/latest/meta-data/ are accepted. An authenticated organization member, including a default 'member' with no project access, can make the server connect to any reachable address, and the resulting HTTP status and status text are persisted and returned to that user.

OpenPanel through commit bad75bdd 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 commit bad75bdd 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 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 by exploiting missing access level validation in mutation resolvers.

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.

OpenPanel before 2.3.0 contains an unauthenticated server-side request forgery vulnerability in the /misc/favicon and /misc/og endpoints that accept an attacker-supplied url parameter with insufficient validation. Attackers can force the API to fetch arbitrary internal hosts and cloud metadata endpoints, with small responses returned verbatim enabling credential theft and internal service enumeration.

OpenPanel before version 2.3.0 contains a cross-tenant broken object level authorization vulnerability in the report.getLayouts and report.resetLayout tRPC procedures that fail to scope dashboard queries to the caller's project. Authenticated attackers can supply their own projectId with a victim organization's guessable dashboardId to read confidential report definitions or permanently delete dashboard layouts across tenant boundaries.
