Description
Coop is an open source review and moderation tool from ROOST. Prior to 1.0.0, an unauthenticated actor can query `Query.allOrgs` through `/api/v1/graphql` on a publicly accessible deployment and obtain data for all organizations, including organization IDs, names, email addresses, website URLs and on-call alert email addresses. The `usersWhoCanReviewEveryQueue` field also exposes reviewing users' IDs, email addresses, first and last names, roles, permissions and creation dates. Running the service on an authenticated private network prevents outside actors from directly querying the GraphQL API. This issue is fixed in version 1.0.0.

AI Analysis

Impact

The vulnerability allows an unauthenticated participant to issue a GraphQL query to the public /api/v1/graphql endpoint and retrieve extensive organization data. The exposed fields include organization IDs, names, email addresses, website URLs and on‑call alert addresses, as well as reviewing users’ IDs, emails, personal names, roles, permissions and creation dates. This disclosure can reveal sensitive operational information, potentially enabling social engineering or further compromise.

Affected Systems

Vendors: ROOST; Product: Coop; Affected versions: any release prior to 1.0.0. Only applying the 1.0.0 update removes the vulnerability. The public endpoint is available on standard deployments without authentication. No specific OS or infrastructure details are listed.

Risk and Exploitability

The CVSS score of 8.7 indicates high severity. EPSS is currently unavailable but the lack of a KEV listing does not reduce the likelihood of exploitation. The likely attack vector is an unauthenticated HTTP request to /api/v1/graphql, requiring no credentials, which aligns with CWE‑306 (Authentication Bypass). An attacker who can reach the public GraphQL interface can harvest personal and organizational data that could be leveraged for targeted phishing or insider‑credential fraud.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Coop to version 1.0.0 or newer, which removes the vulnerable GraphQL query.
  • If immediate upgrade is not possible, block external access to /api/v1/graphql or limit the endpoint to trusted internal networks.
  • Apply network‑level controls such as firewall rules or reverse‑proxy authentication to prevent unauthenticated access to the GraphQL API.
