**Updated** SonicWall Warns of Maximum-Severity SSRF Vulnerability in SMA1000 Gateways
SonicWall has confirmed that this vulnerability has now been exploited in the wild. If you have not applied patches, it is recommended that you do so urgently.
More Reading / Information
Original Advisory:
SonicWall has released a patch for CVE-2026-102255 (CVSS 10/10), a server-side request forgery (SSRF) vulnerability affecting SMA1000 remote access appliances. The issue stems from an alternate access path in the Appliance WorkPlace interface. Exploitation of this vulnerability could allow an unauthenticated attacker to force the appliance to make internal requests and perform unauthorized operations.
Affected Versions
- SMA1000 6210, 7210, and 8200v appliances running 12.4.3-03526, 12.5.0-02952, and older versions.
Recommendations
Apply the latest patches.

Critical GitLab Remote Code Execution Vulnerability
GitLab has released a patch for a critical vulnerability, CVE-2026-97229 (CVSS 10/10), affecting the CI/CD Regular Expression Compiler. The flaw is caused by an integer overflow and insufficient validation of regular expressions, allowing an unauthenticated remote attacker to execute arbitrary code on the GitLab server using a specially crafted regular expression in a CI/CD configuration. GitLab.com has already been patched, while administrators of self-managed GitLab instances are being urged to update immediately.
Affected Versions
- GitLab CE/EE 19.2 prior to 19.2.8.
- GitLab CE/EE 19.3 prior to 19.3.5.
- GitLab CE/EE 19.4 prior to 19.4.2.
Recommendations
Upgrade self-managed GitLab instances to versions 19.2.8, 19.3.5, 19.4.2, or later.

Ivanti Connect Secure Vulnerability Actively Exploited
Ivanti has released a patch for an exploited vulnerability affecting its Connect Secure enterprise SSL VPN product. The vulnerability, CVE-2026-104935 (CVSS 8.6/10), is an authentication bypass that allows a remote attacker to execute arbitrary commands. It has been confirmed that exploitation of this vulnerability has been seen in the wild this month. Attackers have been chaining it with additional vulnerabilities to achieve root-level code execution, steal credentials, and exfiltrate sensitive information. CISA has added this vulnerability to its Known Exploited Vulnerabilities catalog and is urging organizations to patch immediately.
Affected Versions
- Ivanti Connect Secure 22.8R2.4 and earlier.
- Ivanti Connect Secure 25.1.2.2 and earlier.
- Ivanti Connect Secure 25.1.1.1 and earlier.
Recommendations
Upgrade to versions 22.8R2.5, 25.1.3.0/25.1.3.1, or 25.1.1.2 as soon as possible.

Fortinet Patches Multiple Vulnerabilities
Fortinet has released patches for thirteen vulnerabilities, two of which are critical severity affecting FortiSIEM and FortiSandbox. The vulnerabilities, CVE-2026-106173 and CVE-2026-107656, allow an attacker to bypass authentication and execute arbitrary code. These patches also resolve four high-severity SQL injection vulnerabilities in multiple products that could allow authenticated attackers to execute arbitrary code.

Cisco Patches Critical Nexus Switch Vulnerabilities
Cisco has released patches for multiple critical vulnerabilities affecting Nexus 3000 and 9000 Series switches running NX-OS. Five vulnerabilities affecting NX-API, Next Generation OAM (NGOAM), and MPLS OAM could allow unauthenticated remote attackers to execute arbitrary code with root privileges or crash vulnerable switches, resulting in denial-of-service. Exploitation requires specific affected features to be enabled, and Cisco has not observed these vulnerabilities being exploited in the wild.
Affected Versions
Cisco Nexus 3000 and Nexus 9000 Series switches running vulnerable NX-OS releases with affected NX-API, NGOAM, or MPLS OAM features enabled.
Recommendations
Apply the latest patches.

Recommendations
Please review your environment to ensure the above-mentioned issues are patched in a timely manner. It is security best practice to regularly update and/or patch software to the latest versions. The vulnerabilities above highlight the security benefits of limiting deployed software to “vendor-supported versions” only. This dramatically increases the likelihood that new vulnerabilities have a patch issued for them. Likewise, CyberMaxx strongly encourages maintaining an inventory of current software in your environment, which helps ensure and inform your patch and vulnerability management program.
