    Title
    [KIS-2026-01] Blesta <= 5.13.1 (confirm_url) Reflected Cross-Site Scripting Vulnerability
    Summary
    --------------------------------------------------------------------------- Blesta <= 5.13.1 (confirm_url) Reflected Cross-Site Scripting Vulnerability --------------------------------------------------------------------------- [-] Software Link: https://www.blesta.com [-] Affected Versions: All versions from 3.2.0 to 5.13.1. [-] Vulnerability Description: User input passed through the "confirm_url" GET parameter to the /dialog/confirm and /client_dialog/confirm/ endpoints is not properly sanitized before being used to generate HTML output; specifically, before being used as action attribute of an HTML form. This can be exploited by attackers to perform 2-clicks Reflected Cross-Site Scripting (XSS) attacks. [-] Proof of Concept: An attacker may trick a victim Blesta user into clicking on links like these: http://[blesta]/dialog/confirm/?confirm_url=javascript:alert('XSS') http://[blesta]/client_dialog/confirm/?confirm_url=javascript:eval(atob('YWxlcnQoJ1hTUyBvbiAnK2RvY3VtZW50LmRvbWFpbik=')) When the victim user clicks on the malicious link and then they also click on the "Yes" button, the form will be submitted, and the attacker-controlled JavaScript code will be executed on the victim user's browser. [-] Solution: Apply the vendor patch or upgrade to version 5.13.2 or later. [-] Disclosure Timeline: [19/01/2026] - Vendor notified [22/01/2026] - CVE identifier requested [28/01/2026] - Version 5.13.2 released [31/01/2026] - Version 5.13.3 released to address regressions introduced in 5.13.2 [03/02/2026] - CVE identifier assigned [04/02/2026] - Public disclosure [-] CVE Reference: The Common Vulnerabilities and Exposures project (cve.org) has assigned the name CVE-2026-25616 to this vulnerability.

[-] 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.

    Summary
    -------------------------------------------------------------------------- Blesta <= 5.13.1 (2Checkout) 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 "invoices" POST parameter or the "item-ext-ref" GET parameter when dispatching the Checkout2::validate() or Checkout2::success() method is not properly sanitized before being used in a call to the unserialize() PHP function. This can be exploited by malicious client 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). Successful exploitation of this issue requires the 2Checkout payment gateway to be installed. [-] Proof of Concept: https://karmainsecurity.com/pocs/CVE-2026-25614.php [-] Solution: Apply the vendor patch or upgrade to version 5.13.2 or later.
