CISA Adds SharePoint and Check Point SmartConsole Flaws to Known Exploited Vulnerabilities Catalog

The US Cybersecurity and Infrastructure Security Agency has added two vulnerabilities to its Known Exploited Vulnerabilities catalog after confirming active exploitation. CVE-2026-50522 affects Microsoft SharePoint and allows remote code execution through untrusted data deserialization, carrying a CVSS v3.1 base score of 9.8. A patch was released on July 14, 2026, though exploitation was not observed at the time of disclosure. CVE-2026-16232 impacts Check Point Software Technologies SmartConsole and stems from an authentication bypass that could let attackers obtain administrative privileges and alter security policies. CISA has directed federal agencies to remediate both issues by July 25, 2026, and Check Point has published associated malicious IP addresses. The agency warns that the flaws pose a broad exploitation risk beyond government systems.

The US Cybersecurity and Infrastructure Security Agency (CISA) has issued an alert regarding the active exploitation of vulnerabilities in Microsoft SharePoint and Check Point Software Technologies SmartConsole.

On July 22, 2026, CISA added CVE-2026-50522 and CVE-2026-16232 to its Known Exploited Vulnerabilities (KEV) catalog. Federal agencies have been instructed to apply mitigations by July 25, 2026, while all organizations are urged to take immediate action due to the widespread exploitation risk.

CVE-2026-50522 resides in Microsoft SharePoint and enables remote attackers to execute arbitrary code by deserializing untrusted data. The flaw received a CVSS v3.1 base score of 9.8 and is rated Critical. A security update addressing the issue was included in Microsoft’s July 14, 2026 Patch Tuesday release. Coordinated disclosure occurred, and no exploitation was known at the time the advisory was published.

CVE-2026-16232 affects the SmartConsole management tool from Check Point Software Technologies. The vulnerability stems from improper authentication, allowing attackers to obtain administrative rights and modify security configurations and policies. Check Point has published a list of IP addresses observed in attacks and is advising customers to investigate potential compromises.

Security researchers note that both vulnerabilities are being actively leveraged in the wild, increasing the urgency for patching across enterprise environments.

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.
