Unauthenticated data disclosure and manipulation via weak authentication
Published Feb 20, 2026 · Updated Feb 20, 2026
Improper authentication in Acronis Cyber Protect 15 before build 41800 and 16 before build 39938 allows remote attackers to read and alter sensitive data. Acronis has not published the affected component or the operation that improperly authenticates attacker-controlled requests. No credentials or user interaction are required; successful exploitation permits sensitive-data access and modification and can interrupt service.
