CVE-2026-48001: 
Adobe Commerce vulnerability analysis and mitigation

CVE-2026-48001 is an Information Exposure vulnerability (CWE-200) in Adobe Commerce, Adobe Commerce B2B, Magento Open Source, and Adobe Commerce Events (I/O Events) that could lead to limited disclosure of sensitive information. Disclosed on July 14, 2026, as part of Adobe's security bulletin APSB26-73, the vulnerability affects Adobe Commerce versions up to 2.4.9, 2.4.8-p5, 2.4.7-p10, 2.4.6-p15, 2.4.5-p17, and 2.4.4-p18; Adobe Commerce B2B versions up to 1.5.3, 1.5.2-p5, 1.4.2-p10, 1.3.4-p17, and 1.3.3-p18; Magento Open Source versions up to 2.4.9, 2.4.8-p5, 2.4.7-p10, and 2.4.6-p15; and Adobe Commerce Events (I/O Events) versions 1.6.0 through 1.20.0. It carries a CVSS v3.1 base score of 3.7 (Low) (Adobe Advisory, GitHub Advisory).

The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), meaning the application inadvertently exposes sensitive data to actors not authorized to access it. The attack vector is network-based, requires no privileges and no user interaction, but has high attack complexity — indicating that successful exploitation depends on conditions beyond the attacker's direct control, such as specific application states or race conditions. No detailed technical write-up or proof-of-concept code has been publicly disclosed at this time (Adobe Advisory, GitHub Advisory).

Successful exploitation results in a limited disclosure of sensitive information from affected Adobe Commerce, Magento Open Source, or Commerce B2B instances, with no impact on integrity or availability. The confidentiality impact is rated Low, meaning only a restricted subset of data may be exposed rather than full system compromise. There is no evidence of lateral movement potential or significant data exfiltration risk associated with this vulnerability given its constrained scope (Adobe Advisory, GitHub Advisory).

Adobe has released security patches addressing this vulnerability as part of the July 2026 security update (APSB26-73). Administrators should upgrade to the following fixed versions: Adobe Commerce 2.4.9-2026-jul, 2.4.8-2026-jul, 2.4.7-2026-jul, 2.4.6-2026-jul, 2.4.5-2026-jul, or 2.4.4-2026-jul; Adobe Commerce B2B 1.5.3-2026-jul, 1.5.2-2026-jul, 1.4.2-2026-jul, 1.3.4-2026-jul, or 1.3.3-2026-jul; Magento Open Source 2.4.9-2026-jul, 2.4.8-2026-jul, 2.4.7-2026-jul, or 2.4.6-2026-jul; and Adobe Commerce Events (I/O Events) version 1.21.0. No configuration-based workarounds have been published; applying the available patch is the recommended remediation (Adobe Advisory).

The CIS (Center for Internet Security) published an advisory noting multiple vulnerabilities in Adobe products patched in July 2026, including CVE-2026-48001, as part of a broader bulletin covering potential arbitrary code execution risks across Adobe's product suite. No notable independent researcher commentary or significant social media discussion specific to this low-severity vulnerability has been observed (CIS Advisory).
