Check Your Adobe Commerce Versions for Critical Code Execution Risk
A severe flaw in older Adobe Commerce releases allows privileged attackers to run arbitrary code without needing user interaction.
Key points
- The National Vulnerability Database lists CVE-2026-92464 as a critical severity issue with a CVSS score of 9.1.
- Affected products include Adobe Commerce, Adobe Commerce B2B, and Adobe Magento Open Source through specific September 2026 release builds.
- Exploitation requires high privileges but does not require any interaction from a user, making silent exploitation possible.
Adobe Commerce and related platforms contain a serious security flaw that allows attackers to execute code if they already hold high privileges on the system.
In plain English
This vulnerability stems from improper input validation, meaning the software fails to correctly check data before processing it. According to the National Vulnerability Database, this weakness is classified as CWE-20. The result is arbitrary code execution within the context of the current user. This means an attacker can run commands that the compromised account is allowed to run.
The background
The National Vulnerability Database assigns this issue the identifier CVE-2026-92464 and rates it as critical with a CVSS score of 9.1. The affected software includes Adobe Commerce up to version 2.4.9-2026-sep, as well as earlier 2.4.x releases. Adobe Commerce B2B versions up to 1.5.3-2026-sep and older 1.4.x and 1.3.x releases are also affected. Adobe Magento Open Source versions up to 2.4.9-2026-sep and prior 2.4.x builds share this risk.
What changes now
An attacker with high privileges can exploit this vulnerability to execute arbitrary code. The National Vulnerability Database states that exploitation does not require user interaction, which means no clicks or logins are needed from victims. The scope of the vulnerability is noted as changed, indicating the impact extends beyond the original request. The source material does not mention a patch or update for this issue.
Key terms explained
Improper input validation occurs when software accepts data without verifying its format or content. Teams usually implement strict checks to ensure inputs match expected patterns. Arbitrary code execution means an attacker can run any program they choose. Check whether your systems restrict what commands privileged accounts can run. Scope changes indicate the vulnerability affects more than just the immediate component.
What to do and how to stay safe: Adobe Commerce
- Verify your installed version of Adobe Commerce, Commerce B2B, or Magento Open Source against the affected list.
- Restrict high-privilege accounts to only those who absolutely require them, reducing the number of potential attackers.
- Monitor system logs for unexpected code execution or unusual process activity from privileged user contexts.
- Plan to apply updates once the vendor provides a confirmed fix for this vulnerability.
