Title
[KIS-2026-02] Blesta <= 5.13.1 (Admin Interface) Multiple PHP Object Injection Vulnerabilities
Summary
--------------------------------------------------------------------------------
Blesta <= 5.13.1 (Admin Interface) Multiple PHP Object Injection Vulnerabilities
--------------------------------------------------------------------------------
[-] Software Link:
https://www.blesta.com
[-] Affected Versions:
All versions from 3.0.0 to 5.13.1.
[-] Vulnerabilities Description:
The vulnerabilities exist because user input passed through the "vars"
and "order_info" POST parameters when dispatching the
/app/controllers/admin_clients.php script, and through the
"$group_name" POST parameter when dispatching the
/app/controllers/admin_company_groups.php script, is not properly
sanitized before being used in a call to the unserialize() PHP
function. This can be exploited by malicious administrator users to
inject arbitrary PHP objects into the application scope, allowing them
to perform a variety of attacks, such as executing arbitrary PHP code
(RCE).
[-] Proof of Concept:
https://karmainsecurity.com/pocs/CVE-2026-25615.php
