Apache Releases HTTP Server 2.4.71 Fixing Critical mod_http2 RCE Flaw CVE-2026-119618
Developers of the Apache HTTP Server have released version 2.4.71 that patches the critical vulnerability CVE-2026-119618. The flaw resides in the mod_http2 module responsible for handling the HTTP/2 protocol and can result in remote code execution.
The issue affects server versions from 2.4.55 through 2.4.70 as well as standalone builds of the mod_h2 module from 2.0.8 to 2.0.42. The root cause is a race condition inside the assign_headers() function where multiple threads access shared data without adequate synchronization, potentially corrupting server memory.
The vulnerability was first reported on 26 October by an open-source code scanner from Anthropic. On 3 November the same issue was independently discovered by Anthony Weems and Simon Scannell of Google Cloud Vulnerability Research.
Red Hat rated the flaw 9.8 out of 10 on the CVSS scale, stating that an unauthenticated attacker can obtain control over the web-server process. Only servers with HTTP/2 enabled are at risk; configurations restricted to HTTP/1.1 are not affected. The company also noted that a reliable exploit has already been shown in public research, although the PoC published on GitHub currently causes only memory corruption and process termination.
According to Wiz, vulnerable Apache instances are present in 64 percent of cloud environments and are reachable from the internet in 51 percent of those cases. Administrators are urged to upgrade to version 2.4.71. If immediate patching is not possible, the attack can be mitigated by temporarily disabling HTTP/2.
The same release also corrects two additional vulnerabilities: CVE-2026-106023 in the mod_md module that can cause server processes to crash, and the low-severity CVE-2026-109163 in mod_vhost_alias.

Microsoft Patches Two BitLocker Vulnerabilities Allowing Encryption Bypass via Physical Access
Microsoft released fixes on November 10, 2026, for two BitLocker vulnerabilities that enable attackers with physical access to bypass disk encryption on Windows systems. CVE-2026-119832 carries a CVSS score of 5.9 and stems from an improperly applied access control, allowing low-privileged local users to read protected data from the system drive without user interaction. CVE-2026-97015 scores 6.8 and involves a buffer overflow in dynamically allocated memory, requiring no prior privileges and classified as low attack complexity. Both flaws affect Windows 10 versions 1809, 21H2 and 22H2, multiple Windows 11 releases, and Windows Server 2019, 2022 and 2025 editions across various processor platforms. The issues directly undermine BitLocker's core purpose of protecting lost, stolen or improperly decommissioned devices. Corresponding updates include KB5131096 for Windows 10 21H2/22H2 and KB5131087 for Windows 11 23H2, with administrators advised to verify coverage for CVE-2026-97015 separately.
Qlik Sense Servers Targeted with Reverse Shell Attacks in October 2026 Campaign
In October 2026, multiple Qlik Sense servers hosted by European Union customers were subjected to attempted reverse shell installations within a three-minute window. The attacks were blocked before execution and originated from a single-line PowerShell command delivered through the Qlik Sense scheduling component. Analysts noted strong similarities to a November 2023 campaign attributed to CACTUS ransomware operators that exploited three specific vulnerabilities: CVE-2023-41265, CVE-2023-41266, and CVE-2023-48365. The observed activity included a Go-based second-stage payload that searched for Apache ActiveMQ processes, harvested local account hashes on Linux, and deployed modified OpenSSH servers for persistence. Infrastructure recovered during the investigation also contained exploits for a 2023 Apache ActiveMQ vulnerability and a 2024 Veeam Backup and Replication flaw, indicating broader targeting intentions. The root vulnerability exploited in the 2026 attempts remains unidentified.
