Summary

JetBrains Hub before 2026.2.52519 is affected. An incorrect authorization flaw (CWE-863) allows privilege escalation because email verification can be forged. A remote attacker with low privileges can gain elevated rights, with high impact to confidentiality, integrity and availability, though exploitation is considered complex.
