CVE-2023-2360Network attack vector

Sensitive information disclosure via permissive CORS policy

Published Apr 28, 2023 · Updated Jan 30, 2025

Permissive CORS policy in Acronis Cyber Infrastructure before 5.2.0-135 allows remote attackers to read sensitive information. Acronis has not identified the affected HTTP endpoint or disclosed how its cross-origin policy admits an untrusted origin. Exploitation requires user interaction and a crafted cross-origin request, and the reported consequence is limited to information disclosure.
