The highest priority threat is an actively exploited zero-day vulnerability in Google Chrome (CVE-2026-85046), which is listed on the CISA KEV list and requires immediate patching. Another critical vulnerability in Sangoma Switchvox (CVE-2026-9586) is also on the CISA KEV list, confirming active exploitation. Additionally, a critical authentication bypass in Citrix NetScaler (CVE-2026-19490) is reportedly being leveraged in attacks. We must prioritize patching for these actively exploited vulnerabilities to mitigate immediate risk.

[CRITICAL] "Google patches actively exploited Chrome zero-day (CVE-2026-85046)"

critical

CVE-2026-85046

KEVEPSS 0.5%

Details

A high-severity type confusion vulnerability in the V8 JavaScript engine allows a remote attacker to execute arbitrary code. The vulnerability is a zero-day, meaning it was exploited before a patch was available. Google has confirmed that an exploit for this CVE exists in the wild.

Affected Systems

Google Chrome versions prior to 152.0.7977.82 for Linux and 152.0.7977.82/.83 for Windows and macOS.

Potential Impact

Successful exploitation could lead to arbitrary code execution on user workstations, enabling attackers to compromise user data, install malware, or pivot to other systems on the network.

Mitigations

Update all Chrome instances to the latest version immediately. Per CISA KEV requirements, patching must be completed by 2026-09-18.

[HIGH] "Sangoma Switchvox Vulnerabilities Exploited in the Wild"

high

CVE-2026-9586

KEVEPSS 11.8%

Details

An unauthenticated SQL injection vulnerability allows a remote, unauthenticated attacker to execute arbitrary code on the underlying operating system of the affected Sangoma Switchvox appliance.

Affected Systems

Sangoma Switchvox versions prior to the latest patched release.

Potential Impact

An attacker could gain full control over the PBX system, potentially leading to eavesdropping on calls, service disruption, or using the system as a foothold to attack the internal network.

Mitigations

Patch all Sangoma Switchvox appliances immediately. Per CISA KEV requirements, patching must be completed by 2026-09-05.

SecurityWeek Draft Post

[CRITICAL] "Critical Citrix NetScaler auth bypass now leveraged in attacks"

critical

CVE-2026-19490

EPSS 3.4%

Details

A critical-severity authentication bypass vulnerability in Citrix NetScaler is reportedly being targeted in the wild. The flaw allows an attacker to bypass authentication measures, though specific details of the attack chain are not provided.

Affected Systems

Citrix NetScaler (specific versions to be confirmed based on vendor advisory).

Potential Impact

Bypassing authentication on a network appliance like NetScaler could grant attackers access to internal networks and sensitive applications, posing a significant risk of data breach and lateral movement.

Mitigations

Monitor Citrix security bulletins for patches and apply them as soon as they become available. Isolate affected appliances if patching is not immediately possible.

[CRITICAL] "Over 440,000 Exploit Attempts Target Super Forms and Elementor Pro RCE Flaws"

critical

CVE-2026-14894

EPSS 5.3%

Details

A critical (CVSS 9.8) missing file type validation vulnerability in the Super Forms WordPress plugin allows unauthenticated attackers to upload arbitrary files, including web shells, leading to remote code execution.

Affected Systems

WordPress sites using the 'Super Forms – Drag & Drop Form Builder' plugin (versions to be confirmed).

Potential Impact

Successful exploitation could lead to a complete compromise of the web server, resulting in website defacement, data theft, or the server being used to host malware or launch further attacks.

Mitigations

Update the Super Forms plugin to the latest patched version immediately. Review web server file systems for any suspicious or unknown files.

[HIGH] "12-Year-Old PostgreSQL Vulnerability Enables Database, Server Takeover"

high

CVE-2026-6471

EPSS 0.3%PoC

Details

A 12-year-old vulnerability, dubbed PostGREShell, allows an attacker with low-level replication access to execute arbitrary code as the database server's operating system user. This can be escalated to permanent superuser privileges and a persistent backdoor. Public exploit code is available.

Affected Systems

PostgreSQL versions before 18.6, 17.11, 16.15, 15.19, and 14.24.

Potential Impact

An attacker could gain full control over the database server, leading to theft or modification of all stored data, and could use the compromised server to move laterally within the network.

Mitigations

Update all PostgreSQL instances to the latest patched versions. Review accounts with REPLICATION privileges and restrict them to trusted users only.
