Summary
APITable through 1.13.0-beta.1 contains an incorrect authorization vulnerability in NodePermissionGuard that fails to enforce node-level access control when permission lookups throw exceptions. Attackers with valid Fusion API tokens can write attachments to private datasheets they have been explicitly denied access to by exploiting the unhandled exception in the permission guard.
Risk Assessment
The risk includes unauthorized access to private data and potential modification of datasheet content, leading to confidentiality and integrity breaches.
Recommendation
Update APITable to a version that properly handles exceptions in the permission guard. Additionally, review logs for unauthorized access attempts.
Other vulnerabilities in APITable
See all- CVE-2026-84485High
APITable through version 1.13.0-beta.1 exposes the internal organization loadOrSearch endpoint without authentication, allowing unauthenticated attackers to retrieve member names, email addresses, and team hierarchy. Attackers can query the endpoint with space identifiers obtained from shared links or public templates to enumerate the complete member directory of any workspace.
- CVE-2026-80208High
APITable through 1.13.0-beta.1 annotates both getUserHistories and closePausedUserAccount with requiredLogin = false. ResourceInterceptor honors that annotation by returning before any session or API key is validated, and the nginx gateway proxies every /api request to the backend. An unauthenticated attacker can enumerate accounts in the cooling-off period and close them, deleting account data and preventing recovery.
- CVE-2026-80207Medium
Vulnerability in APITable up to 1.13.0-beta.1 allows an unauthenticated attacker to create notifications in the system. Missing required login for the create handler of InternalNotifyController and nginx proxy allow access to the API.
