CVE-2026-33302 is an access control bypass vulnerability in OpenEMR versions prior to 8.0.0.2, where the system's ACL function incorrectly prioritizes "allow" rules over explicit "deny" rules, preventing administrators from revoking access for users who are part of an allowed group. This flaw carries a CVSSv3.1 score of 8.1 HIGH, indicating that a low-privileged attacker can exploit it remotely with low complexity to achieve high confidentiality and integrity impacts. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed on CISA's KEV catalog.
