OS Command Injection in Laravel Backpack CRUD Stats::makeCurlRequest

IdentifiersCVE-2026-54182CWE-78

CVE-2026-54182 is an OS command injection vulnerability in Laravel Backpack CRUD. The flaw is in Backpack\CRUD\Stats::makeCurlRequest, where attacker-controlled input from the HTTP Host header is incorporated into shell command construction. Because the vulnerable implementation invokes an operating system command using insufficiently neutralized external input, a remote unauthenticated attacker can inject arbitrary shell metacharacters and execute commands on the underlying server. The issue affects vulnerable Laravel Backpack CRUD releases prior to the patched versions that replaced the shell-based request logic with a Guzzle-based implementation.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows pre-authentication remote command execution in the context of the web server process. An attacker can use this access to read application configuration and environment data, obtain database credentials and API secrets, inspect or modify accessible filesystem contents, pivot to reachable internal services, and potentially establish further persistence or conduct follow-on compromise depending on the privileges of the web application account and surrounding environment.

Mitigation

If you can’t patch tonight, do this now.

Apply vendor patches immediately. As interim risk reduction, enforce strict Host header validation and normalization at the web server, reverse proxy, load balancer, or application gateway so malformed or unexpected Host values are rejected before reaching the application. Restrict or disable dangerous process-execution functions for web-facing PHP workloads where operationally feasible, and run the application with least privilege to limit post-exploitation impact. These measures reduce exploitability but do not fully remediate the vulnerability.

Remediation

Patch, then assume compromise.

Upgrade Laravel Backpack CRUD to a patched release that removes shell-command construction from Stats::makeCurlRequest and uses the safer Guzzle-based implementation. Fixed versions are 4.1.70 and later for the 4.1.x branch, 5.6.2 and later for the 5.x branch, 6.8.13 and later for the 6.x branch, and 7.0.36 and later for the 7.x branch. Validate that all deployed instances, including staging and administrative environments, are running a fixed version.
