CVE-2025-49555 is a Cross-Site Request Forgery (CSRF) vulnerability affecting multiple versions of Adobe Commerce, specifically versions 2.4.4-p14 through 2.4.9-alpha1 and earlier. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a web application without their consent or knowledge. In this case, the vulnerability allows a high-privileged attacker to induce a victim, who is authenticated on Adobe Commerce, to perform unintended actions that could lead to privilege escalation. This means that the attacker could leverage the victim's session to execute commands or modify sensitive data that the victim is authorized to access. Exploitation requires user interaction, such as visiting a malicious website or clicking a crafted link, which then triggers the unauthorized action within the victim's authenticated session. The vulnerability's scope is changed, indicating that the impact extends beyond the initially affected component, potentially affecting other parts of the system or user privileges. The CVSS v3.1 base score of 8.1 reflects a high severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), high privileges required (PR:H), user interaction required (UI:R), scope changed (S:C), and high impact on confidentiality and integrity (C:H/I:H) but no impact on availability (A:N). No known exploits are currently reported in the wild, and no official patches are linked yet, suggesting that organizations should prioritize monitoring and mitigation efforts to prevent exploitation once patches become available.

For European organizations using Adobe Commerce, this vulnerability poses a significant risk due to the potential for privilege escalation via CSRF attacks. Adobe Commerce is widely used by e-commerce businesses across Europe, including small to large enterprises managing online storefronts. Successful exploitation could lead to unauthorized modification or disclosure of sensitive customer data, financial information, or business-critical configurations. This could result in data breaches, financial losses, reputational damage, and regulatory penalties under GDPR. The requirement for user interaction means phishing or social engineering campaigns could be used to lure authenticated users into triggering the exploit. Given the e-commerce sector's critical role in European economies and the sensitivity of personal and payment data processed, the impact could be severe, especially for organizations lacking robust web security controls or user awareness programs.

European organizations should implement the following specific mitigations: 1) Immediately review and apply any official Adobe Commerce security patches once released. 2) Implement anti-CSRF tokens and verify their presence and validity on all state-changing requests within Adobe Commerce to prevent unauthorized requests. 3) Harden web application firewalls (WAFs) to detect and block suspicious CSRF attack patterns and anomalous HTTP requests targeting Adobe Commerce endpoints. 4) Conduct user awareness training focused on phishing and social engineering risks to reduce the likelihood of users clicking malicious links. 5) Restrict administrative access to Adobe Commerce to trusted networks or VPNs to reduce exposure. 6) Monitor logs for unusual activity indicative of CSRF exploitation attempts, such as unexpected privilege changes or configuration modifications. 7) Employ Content Security Policy (CSP) headers to limit the execution of untrusted scripts that could facilitate CSRF attacks. 8) Regularly audit and minimize the number of users with high privileges to reduce the attack surface. These measures go beyond generic advice by focusing on Adobe Commerce-specific controls and user behavior.
