Stored Cross-Site Scripting (XSS) vulnerability in Prestashop 8.1.7, due to the lack of proper validation of user input through ‘/<admin_directory>/index.php’, affecting the ‘link’ parameter. This vulnerability could allow a remote user to send a specially crafted query to an authenticated user and steal their cookie session details.

ps_contactinfo, a PrestaShop module for displaying store contact information, has a cross-site scripting (XSS) vulnerability in versions up to and including 3.3.2. This can not be exploited in a fresh install of PrestaShop, only shops made vulnerable by third party modules are concerned. For example, if the shop has a third party module vulnerable to SQL injections, then ps_contactinfo might execute a stored cross-site scripting in formatting objects. Commit d60f9a5634b4fc2d3a8831fb08fe2e1f23cbfa39 keeps formatted addresses from displaying a XSS stored in the database, and the fix is expected to be available in version 3.3.3. No workarounds are available aside from applying the fix and keeping all modules maintained and update.

An issue in Prestashop v.8.1.7 and before allows a remote attacker to execute arbitrary code via the module upgrade functionality. NOTE: this is disputed by multiple parties, who report that exploitation requires that an attacker be able to hijack network requests made by an admin user (who, by design, is allowed to change the code that is running on the server).

In the module "Custom links" (pk_customlinks) <= 2.3 from Promokit.eu for PrestaShop, a guest can perform SQL injection. The script ajax.php have a sensitive SQL call that can be executed with a trivial http call and exploited to forge a SQL injection.

PrestaShop is an open source e-commerce web application. In PrestaShop 8.1.5, any invoice can be downloaded from front-office in anonymous mode, by supplying a random secure_key parameter in the url. This issue is patched in version 8.1.6. No known workarounds are available.

PrestaShop is an open source e-commerce web application. A cross-site scripting (XSS) vulnerability that only affects PrestaShops with customer-thread feature flag enabled is present starting from PrestaShop 8.1.0 and prior to PrestaShop 8.1.6. When the customer thread feature flag is enabled through the front-office contact form, a hacker can upload a malicious file containing an XSS that will be executed when an admin opens the attached file in back office. The script injected can access the session and the security token, which allows it to perform any authenticated action in the scope of the administrator's right. This vulnerability is patched in 8.1.6. A workaround is to disable the customer-thread feature-flag.

PrestaShop is an open-source e-commerce platform. Starting in version 8.1.0 and prior to version 8.1.4, PrestaShop is vulnerable to path disclosure in a JavaScript variable. A patch is available in version 8.1.4.

In the module "Sliding cart block" (blockslidingcart) up to version 2.3.8 from PrestashopModules.eu for PrestaShop, a guest can perform SQL injection.

An issue in 202 ecommerce Advanced Loyalty Program: Loyalty Points before v2.3.4 for PrestaShop allows unauthenticated attackers to arbitrarily change an order status.

PrestaShop is an open-source e-commerce platform. Prior to version 8.1.3, the isCleanHtml method is not used on this this form, which makes it possible to store a cross-site scripting payload in the database. The impact is low because the HTML is not interpreted in BO, thanks to twig's escape mechanism. In FO, the cross-site scripting attack is effective, but only impacts the customer sending it, or the customer session from which it was sent. This issue affects those who have a module fetching these messages from the DB and displaying it without escaping HTML. Version 8.1.3 contains a patch for this issue.
