CVE-2026-27407 describes an incorrect privilege assignment vulnerability (CWE-266) in Meow Apps AI Engine affecting versions up to and including 3.4.9. Specifically, users with editor privileges can escalate their permissions beyond intended limits, potentially gaining higher-level access. The CVSS 3.1 base score is 7.2, reflecting network attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available, and the product is not a cloud service.

Successful exploitation allows an attacker with editor privileges to escalate their access rights, potentially leading to full compromise of the system's confidentiality, integrity, and availability. This could enable unauthorized actions beyond the editor role, affecting critical system functions.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict editor-level access to trusted users only and monitor for suspicious activity related to privilege escalation attempts.
