Attack Chain

1. Attacker crafts a malicious URL containing a payload designed to trigger an SSRF vulnerability in the Adobe Commerce application.
2. Attacker distributes the crafted URL via phishing or other social engineering techniques.
3. Unsuspecting victim clicks on the malicious URL.
4. The Adobe Commerce application, upon processing the URL, makes an unintended request to an internal or external resource controlled by the attacker.
5. The attacker intercepts or observes the response from the targeted resource.
6. If the targeted resource contains sensitive data or configuration information, the attacker gains unauthorized access.
7. Attacker leverages the gained information to bypass security measures within the Adobe Commerce application.
8. Attacker gains unauthorized read access to sensitive data.

Impact

Successful exploitation of CVE-2026-34647 can lead to a security feature bypass in Adobe Commerce, potentially granting attackers unauthorized read access to sensitive data. This could include customer data, internal configuration details, or other confidential information stored within the affected system. The impact is heightened by the requirement of user interaction, making social engineering a key component of the attack.

Recommendation

• Apply the latest security patches released by Adobe to address CVE-2026-34647 in Adobe Commerce versions 2.4.9-beta1 and earlier.
• Deploy the Sigma rule Detect Adobe Commerce SSRF via crafted URL to detect potential exploitation attempts in web server logs.
• Educate users about the risks of clicking on suspicious URLs to mitigate the social engineering aspect of this vulnerability.
