CVE-2026-44730: OpenCTI: Privilege escalation via graphQL API abusable by organization admins, due to incorrect ACL on userEdit relationAdd

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.31% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: OpenCTI-Platform opencti 6.9.7.

Low priority for now. Upgrade to OpenCTI-Platform opencti 6.9.7 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to 6.9.7, an organization admin can escalate their privileges by adding a user from a different organization with higher privileges, to their own organization. This is due to incorrect ACL on userEdit relationAdd. This vulnerability is fixed in 6.9.7.
