Summary

CVE-2026-84485 is a missing-authentication vulnerability in APITable, an open-source no-code database/collaboration platform, affecting all versions through 1.13.0-beta.1. The internal organization loadOrSearch endpoint can be queried without any credentials, allowing an unauthenticated attacker to enumerate a workspace’s full member directory — names, email addresses, and team hierarchy. The issue carries a HIGH severity rating due to its unauthenticated, network-exploitable nature and high confidentiality impact.

Technical details

  • Root cause: The InternalOrganizationController‘s loadOrSearch endpoint does not enforce authentication checks, even though related security controls exist elsewhere in the codebase (ResourceInterceptor, LoginContext).
  • Trigger conditions: An attacker needs only a valid space (workspace) identifier, which can be obtained from shared links or public templates — no login or API token is required.
  • Attack vector: Network — a simple unauthenticated HTTP request to the internal endpoint using the harvested space ID.
  • Impact: Disclosure of sensitive organizational data — member names, email addresses, and team/organizational hierarchy — enabling reconnaissance, targeted phishing, or further social-engineering attacks against the organization.

Affected software

  • APITable, all versions through 1.13.0-beta.1 (inclusive)

Severity

  • CVSS v3.1 Base Score: 7.5 (HIGH)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
  • (A CVSS v4.0 score of 8.7 has also been assigned: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N)

Mitigation and recommended actions

  • Immediate: Upgrade to a version of APITable released after 1.13.0-beta.1 once a vendor patch enforcing authentication on the loadOrSearch endpoint is available; monitor the official APITable repository for the fixing release.
  • If no patch is currently available: Restrict or firewall access to internal/organization API endpoints from untrusted networks, avoid exposing space identifiers via public shared links or templates where not necessary, and monitor access logs for unauthenticated requests to internal organization endpoints.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
