IMPORTANT NOTICE: DO NOT REPORT VULNERABILITIES SOLELY TO THE AUTHOR OR MARKETPLACE.
We urge you to report any vulnerabilities directly to us. Our mission is to ensure the safety and security of the PrestaShop ecosystem. Unfortunately, many module developers may not always recognize or acknowledge the vulnerabilities in their code, whether due to lack of awareness, or inability to properly evaluate the associated risk, or other reasons.
Given the rise in professional cybercrime networks actively seeking out these vulnerabilities, it's crucial that any potential threats are promptly addressed and the community is informed. The most effective method to do this is by publishing a CVE, like the one provided below.
Should you discover any vulnerabilities, please report them to us at: report[@]security-presta.org or visit https://security-presta.org for more information.
Every vulnerability report helps make the community more secure, and we are profoundly grateful for any information shared with us.

Summary
- CVE ID: CVE-2024-26469
- Published at: 2024-02-29
- Platform: PrestaShop
- Product: productdesigner
- Impacted release: < 1.178.36 (1.178.36 fixed the vulnerability)
- Product author: Tunis Soft
- Weakness: CWE-918
- Severity: critical (9.1)
Description
In the Product Designer module from Tunis Soft for PrestaShop, an improper validation of url parameter in the method ProductDesignerPixabayModuleFrontController::postProcess can be executed via a trivial HTTP call to forge Server-Side Request.
This vulnerability can be exploited to initiate a HTTP request and get the return, for instance, use the vulnerable website as proxy to attack others websites, exfiltrate data in files under IP restriction or perform a path traversal attack.
This exploit uses a PrestaShop front controller and most attackers can conceal the module controller’s path during the exploit, so you will never know within your conventional frontend logs that it exploits this vulnerability. You will only see “POST /” inside your conventional frontend logs. Activating the AuditEngine of mod_security (or similar) is the only way to get data to confirm this exploit.
