Buffer under-read vulnerability in Apache Tomcat meant that a large non-blocking write could result in the response body being split between the current request and the next request received on that connection leading most likely to failure of the second request and possibly leakage of data from the first response to the second. This issue affects Apache Tomcat: from 11.0.0-M25 through 11.0.26. Users are recommended to upgrade to version 11.0.27, which fixes the issue.

Between April and July 2026, AOMEI Backupper, a Windows backup and disk cloning software, was compromised multiple times in short-lived supply chain attack windows. During these brief periods, users received a downloader for the ShinyRoad modular backdoor framework. The attacker, tracked as UNC7017, tampered with update server configurations to redirect users to malicious payloads, including the CrossRoad dropper, a modified Radmin Server with a malicious DLL, and the Adaptix C2 framework. The campaign used ephemeral tampering windows lasting only five to ten minutes, reverting quickly to authentic versions, which complicated detection. The attack affected a broad range of users opportunistically, with some higher education, IT services, and telecommunications organizations in multiple countries identified as compromised. AOMEI initially dismissed reports of tampering but later took corrective actions after repeated notifications.
