U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Adobe and WSO2 flaws to its Known Exploited Vulnerabilities catalog.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the following vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog:

• CVE-2026-5430 WSO2 Multiple Products Path Traversal Vulnerability
• CVE-2026-71362 Adobe Commerce and Magento Incorrect Authorization Vulnerability

The first flaw added to the catalog, tracked as CVE-2026-5430 (CVSS score 10.0), is an authentication bypass in multiple WSO2 products caused by improper verification of JWT signatures, allowing an attacker to use an unsupported signing algorithm to gain unauthorized access and potentially take over accounts.

The second flaw added to the catalog, tracked as CVE-2026-71362 (CVSS score 9.1), is an incorrect authorization vulnerability in Adobe Commerce that can allow an unauthenticated attacker to escalate privileges and gain access to sensitive resources without user interaction. In August 2026, hackers began targeting CVE-2026-71362 shortly after its public disclosure. The vulnerability allows unauthenticated attackers to switch customer sessions, hijack accounts and access private data.

Cybersecurity firm Sansec blocked the first exploitation attempts after Adobe published its advisory. The flaw affects Commerce, Commerce B2B and Magento Open Source versions through the July 2026 patches. Adobe released an isolated fix and urged users to patch.

“Adobe has released APSB26-92 as isolated patch files. The update fixes seven vulnerabilities, including an unauthenticated customer account takeover with a CVSS score of 9.1. Sansec Shield already blocks exploitation attempts.” reads the advisory published by Sansec. “Sansec reviewed the patch and confirmed that the vulnerability lets attackers switch a customer session to another customer account. This gives them access to the victim’s account and private customer data.”

Sansec pointed out that an attacker can exploit the flaw without an existing account, administrator privileges, or user interaction.

Adobe fixed how Magento handles customer identity in account sessions. The remaining flaws include stored cross-site scripting and authorization issues.

According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure.

CISA orders federal agencies to fix the flaws by September 27, 2026.

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Microsoft Windows, N-able N-central, and Adobe flaws to its Known Exploited Vulnerabilities catalog.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the following vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog:

• CVE-2026-75650 Adobe Commerce and Magento Improper Neutralization of Special Elements Used in a Template Engine Vulnerability
• CVE-2026-81963 Microsoft Windows Link Following Vulnerability  
• CVE-2026-85880 Microsoft Windows Heap-Based Buffer Overflow Vulnerability 
• CVE-2026-86218 N-able N-central Static Code Injection Vulnerability 

CVE-2026-75650 (CVSS score of 10.0) is an Adobe Commerce and Magento improper neutralization of special elements in a template engine vulnerability that can lead to unauthenticated remote code execution. The flaw, tracked as StyleSmuggler, has been actively exploited in the wild since September 4, with attackers reportedly using it to deploy web shells and backdoors, Sansec researchers warned. The flaw lets unauthenticated attackers run code on vulnerable online stores. Sansec researchers say it affects current Magento Open Source releases, including 2.4.7, 2.4.8 and 2.4.9. According to the experts, exploitation began on September 4. StyleSmuggler works by placing PHP code into Magento’s templating path and later causing the platform to evaluate it. The first stage creates or poisons a record, while the second stage turns a routine email-rendering process into remote code execution.

CVE-2026-81963 (CVSS score of 7.8) is a Microsoft Windows Update Stack link-following vulnerability that allows a local attacker to gain higher privileges. Microsoft has confirmed that the flaw is being actively exploited in the wild. The vulnerability lets an attacker follow a malicious link and escalate privileges. It is the first Update Stack vulnerability that Microsoft has confirmed attackers are actively exploiting.

CVE-2026-85880 (CVSS score of 7.8) is a Microsoft Windows heap-based buffer overflow in the Advanced Local Procedure Call (ALPC) component that allows a local attacker to elevate privileges to SYSTEM. Microsoft has confirmed active exploitation of the vulnerability.

CVE-2026-86218 (CVSS score of 10.0) – N-able N-central static code injection vulnerability that allows a pre-authenticated remote attacker to execute arbitrary code on vulnerable systems. The flaw has been exploited in the wild and N-able released an emergency hotfix to address it.

According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure.

CISA orders federal agencies to fix the Windows flaws by September 22, while the remaining must be addressed by September 11, 2026.
