Summary
FroshAdminer Adminer UI is accessible without admin session
Unauthenticated access to Adminer UI
Details
The Adminer route (/admin/adminer) was accessible without Shopware admin authentication. The route was configured with auth_required=false and performed no session validation, exposing the Adminer UI to unauthenticated users.
Note: Database access itself requires credentials that are only set through the ACL-protected API endpoint. Direct database access without prior admin login is not possible through this vulnerability alone.
Workarounds
Deactivate or uninstall the plugin.
Impact
An unauthenticated user could access the Adminer interface, potentially disclosing version information or exploiting Adminer-specific vulnerabilities.
A critical operation is accessible without requiring any authentication. Typical impact: any user can invoke the privileged function.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Version 2.2.1 adds session validation. The Adminer route now verifies an authenticated session flag before rendering, returning HTTP 403 otherwise.
Frequently Asked Questions
- What is CVE-2026-25878? CVE-2026-25878 is a medium-severity missing authentication for critical function vulnerability in frosh/adminer-platform (composer), affecting versions < 2.2.1. It is fixed in 2.2.1. A critical operation is accessible without requiring any authentication.
- Which versions of frosh/adminer-platform are affected by CVE-2026-25878? frosh/adminer-platform (composer) versions < 2.2.1 is affected.
- Is there a fix for CVE-2026-25878? Yes. CVE-2026-25878 is fixed in 2.2.1. Upgrade to this version or later.
- Is CVE-2026-25878 exploitable, and should I be worried? Whether CVE-2026-25878 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-25878 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
