Critical Remote Code Execution Flaw Patched in Veeam ONE Backup Management Product
Veeam Software has disclosed multiple serious vulnerabilities in its backup environment operations management product Veeam ONE. The company published a security advisory on July 29, 2026, confirming that six vulnerabilities have been resolved in the latest release.
The most critical issue, identified as CVE-2026-64633, affects the agent host component and allows remote code execution without any authentication. The flaw received the maximum CVSS v4.0 base score of 10.0 and has been rated Critical, the highest severity level in the four-tier scale.
Another notable vulnerability, CVE-2026-58075, enables unauthenticated reading of arbitrary files, which can subsequently lead to local privilege escalation. This issue was assigned a CVSS base score of 8.7.
Veeam has made updated versions available that address all six vulnerabilities. Organizations running Veeam ONE are strongly advised to apply the fixes without delay to prevent potential exploitation of the remote code execution flaw.

Critical Vulnerability CVE-2026-76519 in Cisco Secure Email Gateway Allows Arbitrary File Writes Without Authentication
Cisco Systems has disclosed a critical vulnerability in its Cisco Secure Email Gateway product that affects the Advanced Malware Protection feature responsible for processing email attachments. The flaw, tracked as CVE-2026-76519, permits unauthenticated attackers to write arbitrary files to the underlying operating system by sending a specially crafted email attachment. Successful exploitation can lead to remote command execution with root privileges. The vulnerability received a CVSS v3.1 base score of 9.8 and is rated Critical. Cisco confirmed active exploitation of the issue in October 2026, shortly after publishing the security advisory on October 14, 2026. This marks the second publicly disclosed exploited vulnerability in the product within a short period, though the flaws are unrelated.
Cyberattack Exploits Exposed Danfoss Refrigeration Controllers Across French Supermarkets
A remote cyberattack targeted Danfoss AK-SM 8xxA Series controllers in French supermarkets, allowing attackers to manipulate refrigeration parameters and trigger defrost cycles that raised temperatures and spoiled food stock. The incident impacted an estimated 250 to 350 stores belonging to major chains including Intermarché, Carrefour Market, Leclerc, and others. Paris prosecutors have opened a large-scale investigation into the attack and associated damages, including potential fires. The root cause traces to outdated software on internet-exposed OT management interfaces, with multiple CVEs enabling authentication bypass and remote code execution. Thousands of similar Danfoss systems remain publicly accessible worldwide, highlighting persistent OT exposure risks. Immediate remediation steps include closing web consoles, enforcing VPN access, and applying updates to versions 4.2 and 4.3.1 or later.
Three Zero-Days Chained in Ivanti Connect Secure Grant Root Access Without Login
An attacker chained three zero-day vulnerabilities in Ivanti Connect Secure to execute commands as root without authentication. The compromised appliance was running the fully patched version 22.8R2.4 when exploitation began on October 3. Volexity discovered the intrusion, attributed the activity to UTA0576 with low confidence in criminal rather than espionage motives, and reported the flaws to the vendor. Ivanti acknowledged limited in-the-wild exploitation on October 13. The first two issues, an authentication bypass and remote code execution, were combined under CVE-2026-104935 with a CVSS score of 8.6, allowing code execution as the cgi-server user. A third privilege-escalation flaw then elevated access to root. The final flaw lacked a patch at disclosure time, with a fix promised in an upcoming release. CISA classified the exploitation as active with total technical impact.
