Security NEXT has released its weekly ranking of the most-read articles published between July 26 and August 1, 2026. The list is led by reports of serious vulnerabilities in several major enterprise and consumer platforms.

The top story covers newly disclosed critical flaws in VMware ESX and VMware vCenter, accompanied by official patches. Second place went to confirmation from U.S. authorities that threat actors are actively exploiting vulnerabilities in FortiOS and VeloCloud Orchestrator.

Google issued a large security update for Chrome that resolves 370 vulnerabilities. A separate entry highlights a flaw in the Java data-conversion library fastjson that has already been observed in exploitation attempts.

Apple released iOS 26.6 and iPadOS 26.6, addressing 87 security issues. Cisco warned customers about a vulnerability in its firewall management product Cisco FMC that is already being exploited in the wild.

Other notable items include a cyber-attack on an ANA Group online store that may have resulted in the leakage of personal information, a serious vulnerability in OpenAM, an update for Node.js fixing 11 issues, and a critical flaw named KindaRails2Shell affecting Ruby on Rails.

Telegram for Android Patches Voice Call Vulnerability Enabling Code Execution

Security researchers at NebuSec disclosed a vulnerability in Telegram for Android that allowed remote code execution after a victim answered a voice call. The flaw affected versions from 8.6.2 through 12.10.3 and was fixed in release 12.10.4 at the end of September. The issue stemmed from improper handling of MediaState service messages that carry microphone, camera, and video rotation data during calls. When a required field was missing, the application accessed invalid memory. NebuSec discovered the bug using its Code Security product running on a GPT-5.4 model and confirmed exploitation on ARM64 Android devices for personal calls. A demonstration showed the string “HACKED BY NEBUSEC” appearing roughly 30 seconds after the call was accepted. The vulnerability is unrelated to the earlier animated-sticker attack vector.

Yandex Patches Millions of Stations After eMudhra Certificate Keys Compromised

Yandex has automatically deployed security updates to millions of its smart speakers and partner televisions running YaOS between October 21 and 23. The patches address compromised intermediate certificates issued by eMudhra whose private keys consisted of trivial values from 1 to 255. Attackers who obtained these keys could generate fraudulent certificates and perform man-in-the-middle attacks against device HTTPS traffic. Enthusiasts demonstrated that local network control combined with the certificates allowed replacement of server configuration, activation of ADB, and acquisition of root access on the devices. The update removes trust in the affected certificates, overwrites compromised system files, and disables the debug interface. A factory reset restores the vulnerable firmware, so Yandex advises against resets without a compelling reason.

Cisco ASA and FTD Face DoS Vulnerability in SSL VPN Already Exploited in the Wild

Cisco Systems has disclosed a denial-of-service vulnerability affecting its Cisco Secure Firewall ASA and Cisco Secure Firewall FTD products. The flaw, tracked as CVE-2026-76418, resides in the SSL VPN remote access feature and carries a CVSS v3.1 base score of 8.6, rated High severity. Exploitation occurs when secondary authentication is configured on tunnel groups, allowing an attacker to send a crafted request that forces a device reboot without requiring authentication. Cisco confirmed active exploitation of the issue in October 2026. Security updates addressing the vulnerability are now available for both affected product lines. The advisory recommends immediate application of the patches to prevent service disruption.
