Top 10 Security Stories: Critical Flaws in PaperCut NG/MF, Chrome, WatchGuard and Others Dominate Week

Security NEXT has published its weekly ranking of the ten most-read articles between August 30 and September 5 2026. The list is led by a critical vulnerability in PaperCut NG/MF that is already being exploited in the wild. Google Chrome received two separate updates addressing 38 vulnerabilities, including two rated Critical and one zero-day. WatchGuard Fireware OS, SonicWall SMA 1000, Cisco IOS XR and Apache Tomcat also received urgent patches for severe flaws. Three real-world incidents made the top ten: a customer-data breach at 01 Bank, a ransomware infection at Hands HD and a suspected cloud leak at Corona. The ranking reflects strong reader interest in both newly disclosed vulnerabilities and confirmed exploitation cases.

Security NEXT has released its weekly list of the ten most-read articles published between August 30 and September 5 2026. The ranking highlights continued industry focus on high-severity vulnerabilities and confirmed exploitation activity.

The top story concerns a critical vulnerability in PaperCut NG/MF print-management software that has already been observed in active attacks. Second place went to Google’s latest Chrome update that resolved 26 vulnerabilities, two of which were rated Critical. A separate Chrome update addressing 12 additional issues, including a zero-day, also ranked in the top five.

Other notable vulnerability reports include WatchGuard Fireware OS, SonicWall SMA 1000, Cisco IOS XR and Apache Tomcat. WatchGuard and SonicWall advisories both urged immediate patching after proof-of-concept exploits surfaced. Apache Tomcat received fixes for multiple flaws, four of which were rated Critical.

Three confirmed incidents also attracted significant attention. 01 Bank disclosed unauthorized access resulting in customer-information leakage. Hands HD reported a ransomware infection that may have exposed personal data, while Corona confirmed a possible cloud-based leak of customer records.

The weekly ranking underscores the community’s priority on timely vulnerability disclosure and real-world breach reporting.

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.
