CVE-2026-25878 is a vulnerability in the FroshPlatformAdminer plugin for the Shopware e-commerce platform, identified as CWE-306: Missing Authentication for Critical Function. The flaw exists in versions prior to 2.2.1, where the Adminer route (/admin/adminer) was configured with auth_required=false, meaning no Shopware admin authentication or session validation was enforced. Adminer is a database management tool, and exposing its interface without authentication allows unauthenticated attackers to access the database management UI directly over the network. This can lead to unauthorized viewing, modification, or deletion of database contents, severely compromising data confidentiality and integrity. The CVSS 4.0 vector indicates the vulnerability is remotely exploitable (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality partially (VC:L), with no impact on integrity or availability. The vulnerability was publicly disclosed on February 9, 2026, and fixed in FroshPlatformAdminer version 2.2.1. No known exploits have been reported in the wild, but the vulnerability's nature makes it a significant risk for Shopware installations exposing the vulnerable plugin. The root cause is a misconfiguration that disabled authentication on a critical administrative route, violating secure development practices. Attackers leveraging this flaw could gain direct database access, potentially leading to data breaches, data manipulation, or further system compromise.

For European organizations using Shopware with the FroshPlatformAdminer plugin versions prior to 2.2.1, this vulnerability poses a significant risk. Unauthorized access to the Adminer interface can lead to exposure of sensitive customer data, intellectual property, and business-critical information stored in the database. Attackers could manipulate or delete data, disrupting business operations and damaging trust. Given the plugin’s role in database management, exploitation could facilitate further attacks such as privilege escalation, data exfiltration, or ransomware deployment. The impact is particularly severe for e-commerce businesses that rely on Shopware for online transactions and customer management. Regulatory compliance risks also arise, as unauthorized data access may violate GDPR and other data protection laws, potentially resulting in fines and reputational damage. The vulnerability’s network accessibility and lack of required authentication increase the likelihood of exploitation if the vulnerable endpoint is publicly reachable. Organizations with exposed admin interfaces or insufficient network segmentation are at higher risk. Although no exploits are currently known in the wild, the vulnerability’s characteristics warrant urgent attention to prevent potential attacks.

1. Upgrade immediately to FroshPlatformAdminer version 2.2.1 or later, where the authentication requirement for the Adminer route is properly enforced. 2. Restrict network access to the /admin/adminer endpoint using firewalls, VPNs, or IP whitelisting to limit exposure to trusted administrators only. 3. Implement web application firewalls (WAF) with rules to detect and block unauthorized access attempts to the Adminer interface. 4. Conduct thorough audits of Shopware installations to identify any instances running vulnerable plugin versions and verify that no unauthorized access has occurred. 5. Monitor database logs and Shopware admin logs for unusual activity indicative of exploitation attempts. 6. Enforce strong authentication and session management policies for all administrative interfaces. 7. Consider disabling or removing the FroshPlatformAdminer plugin if not strictly necessary, reducing the attack surface. 8. Educate administrators on the risks of exposing database management tools without authentication and ensure secure configuration practices are followed. 9. Regularly review and update security policies to include checks for plugin vulnerabilities and misconfigurations.
