### Summary The administrative proxy route (`cmsproxy`) in Aimeos Pagible CMS is vulnerable to a Server-Side Request Forgery (SSRF) attack via DNS Rebinding. A Time-of-Check to Time-of-Use (TOCTOU) race condition exists between the URL validation phase and the actual HTTP request phase, allowing attackers to access internal network resources and cloud metadata endpoints. ### Details Before executing an HTTP request to fetch external content, the `AdminController::proxy` controller validates the target URL using `\Aimeos\Cms\Utils::isValidUrl($url)`. This function performs a DNS query to verify that the hostname does not resolve to private or reserved IP ranges (e.g., `127.0.0.1`, `10.0.0.0/8`, `169.254.169.254`). If the validation passes, the application proceeds to the "Use" phase, invoking Guzzle/cURL to send the request. However, Guzzle performs a *second* DNS lookup to establish the socket connection. An attacker can exploit this by setting up a malicious DNS server for a domain they control and configuring it with a TTL of 0. 1. During the validation "Check", the DNS server returns a safe, public IP. 2. During the Guzzle "Use", the DNS server returns an internal/private

What to do next
- vendor patch
The original advisory lists fixed boundaries 0.10.4 for aimeos/pagible. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
