Prior to 2.18.0, create-team-invitations and the invitation acceptance path allow a non-owner team administrator to assign the owner role because invitation roles are persisted and applied without the role-ceiling check used by update-team-member-role. An administrator can invite another account as an owner, create multiple owners, and then use the new owner account to obtain owner-only control over the team. This issue is fixed in version 2.18.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":49,"depthScoreParts":{"impact":36.9,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":216441,"id":"CVE-2026-105688","ts":1791295279124,"field":"exploit_available","old":"false","new":"true"}]}
