CVE-2026-48000: 
Adobe Commerce vulnerability analysis and mitigation

CVE-2026-48000 is an Improper Redirect (Open Redirect) vulnerability in Adobe Commerce, Adobe Commerce B2B, Magento Open Source, and Adobe Commerce Events (I/O Events plugin). It allows unauthenticated remote attackers to construct malicious URLs that redirect victims to attacker-controlled sites, potentially enabling credential theft and account takeover. The vulnerability was disclosed and patched on July 14, 2026. Affected versions include Adobe Commerce up to 2.4.9/2.4.8-p5/2.4.7-p10/2.4.6-p15/2.4.5-p17/2.4.4-p18, Adobe Commerce B2B up to 1.5.3/1.5.2-p5/1.4.2-p10/1.3.4-p17/1.3.3-p18, Magento Open Source up to 2.4.9/2.4.8-p5/2.4.7-p10/2.4.6-p15, and Adobe Commerce Events (I/O Events) versions 1.6.0 through 1.20.0. The CVSS v3.1 base score is 6.1 (Medium) per the Adobe advisory, while the GitHub Advisory Database rates it 4.3 (Moderate) (Adobe Advisory, GitHub Advisory).

The vulnerability is classified as CWE-601 (URL Redirection to Untrusted Site / 'Open Redirect'), where the application accepts user-controlled input specifying an external link and uses it in a redirect without adequate validation. An unauthenticated attacker can craft a specially formed URL hosted on or referencing the vulnerable Adobe Commerce or Magento instance that, when followed by a victim, transparently redirects them to an attacker-controlled external site. Exploitation requires no privileges and no special configuration, but does require user interaction — specifically, a victim must click the malicious link. No public proof-of-concept code has been identified (Adobe Advisory, GitHub Advisory).

Successful exploitation enables a security feature bypass, allowing attackers to redirect authenticated or unauthenticated users from a trusted Adobe Commerce or Magento storefront to an attacker-controlled website. The primary risks are credential theft (e.g., via phishing pages mimicking the legitimate store login) and account takeover, which could expose customer payment data, order history, and personal information. Availability and direct confidentiality of server-side data are not impacted by this vulnerability alone, but downstream account compromise could lead to broader data exposure (Adobe Advisory, GitHub Advisory).

1. Reconnaissance: Identify publicly accessible Adobe Commerce or Magento Open Source storefronts running affected versions (up to 2.4.9, 2.4.8-p5, 2.4.7-p10, 2.4.6-p15, 2.4.5-p17, or 2.4.4-p18) using search engines, Shodan, or Censys.
2. Identify redirect parameter: Locate a URL parameter or endpoint in the application that accepts a redirect destination without proper validation (e.g., a returnUrl, redirect, or similar parameter in login, checkout, or account flows).
3. Craft malicious URL: Construct a URL pointing to the legitimate Adobe Commerce/Magento domain but with the redirect parameter set to an attacker-controlled site (e.g., https://legitimate-store.com/customer/account/login/?returnUrl=https://attacker.com/phishing).
4. Deliver to victim: Distribute the crafted URL via phishing email, social media, or other channels, leveraging the trusted domain name to increase click-through likelihood.
5. Harvest credentials: When the victim clicks the link and is redirected to the attacker-controlled site (which may mimic the store's login page), capture submitted credentials or session tokens for account takeover (Adobe Advisory, GitHub Advisory).

• Network: Outbound HTTP redirects (301/302 responses) from the Adobe Commerce/Magento server to external, non-whitelisted domains originating from login, checkout, or account management endpoints.
• Logs: Web server or application access logs showing requests to redirect-capable endpoints (e.g., /customer/account/login/, /checkout/) with returnUrl, redirect, or similar parameters containing external URLs (e.g., http://, https:// pointing to non-store domains).
• Logs: Unusual referrer patterns in analytics or server logs where users arrive at external sites directly from the store's redirect mechanism.
• User Reports: Increased reports from customers of being redirected to unexpected or suspicious pages after clicking store-related links.

Adobe has released patched versions addressing this vulnerability. Users should upgrade to the following or later versions: Adobe Commerce 2.4.9-patched, 2.4.8-p6, 2.4.7-p11, 2.4.6-p16, 2.4.5-p18, or 2.4.4-p19; Adobe Commerce B2B 1.5.3-patched, 1.5.2-p6, 1.4.2-p11, 1.3.4-p18, or 1.3.3-p19; Magento Open Source 2.4.9-patched, 2.4.8-p6, 2.4.7-p11, or 2.4.6-p16; and Adobe Commerce Events (I/O Events) 1.21.0. As a complementary measure, implement server-side URL validation to restrict redirect destinations to trusted domains, and educate users to verify URLs before clicking links from emails or external sources (Adobe Advisory).

The CIS (Center for Internet Security) published an advisory noting multiple vulnerabilities in Adobe products patched in July 2026, including this open redirect issue. Coverage has been limited to automated vulnerability tracking platforms and aggregators, with no notable independent researcher commentary or significant social media discussion identified at this time (CIS Advisory).
