Presta Shop vulnerable to email enumeration
### Impact
An unauthenticated attacker with access to the back-office URL can manipulate the id_employee and reset_token parameters to enumerate valid back-office employee email addresses.

Impacted parties:
Store administrators and employees: their email addresses are exposed.
Merchants: risk of phishing, social engineering, and brute-force attacks targeting admin accounts.

### Patches
PrestaShop 8.2.3

### Workarounds
You must upgrade, or at least apply the changes from the PrestaShop 8.2.3 patch. More information: https://build.prestashop-project.org/news/2025/prestashop-8-2-3-security-release/

PrestaShop file deletion via attachment API
PrestaShop is an open source e-commerce web application. Prior to version 8.1.1, it is possible to delete a file from the server by using the Attachments controller and the Attachments API. Version 8.1.1 contains a patch for this issue. There are no known workarounds.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
PrestaShop is an Open Source e-commerce web application. Prior to versions 8.0.4 and 1.7.8.9, the `ValidateCore::isCleanHTML()` method of Prestashop misses hijackable events which can lead to cross-site scripting (XSS) injection, allowed by the presence of pre-setup `@keyframes` methods. This XSS, which hijacks HTML attributes, can be triggered without any interaction by the visitor/administrator, which makes it as dangerous as a trivial XSS attack. Contrary to other attacks which target HTML attributes and are triggered without user interaction (such as onload / onerror which suffer from a very limited scope), this one can hijack every HTML element, which increases the danger due to a complete HTML elements scope. Versions 8.0.4 and 1.7.8.9 contain a fix for this issue.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
PrestaShop is an Open Source e-commerce web application. Prior to versions 8.0.4 and 1.7.8.9, it is possible for a user with access to the SQL Manager (Advanced Options -> Database) to arbitrarily read any file on the operating system when using SQL function `LOAD_FILE` in a `SELECT` request. This gives the user access to critical information. A patch is available in PrestaShop 8.0.4 and PS 1.7.8.9

Improper Input Validation
PrestaShop is an open source e-commerce web application. Prior to version 8.1.1, it is possible to delete files from the server via the CustomerMessage API. Version 8.1.1 contains a patch for this issue. There are no known workarounds.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
PrestaShop is an open source e-commerce web application. Prior to version 8.1.1, SQL injection possible in the product search field, in BO's product page. Version 8.1.1 contains a patch for this issue. There are no known workarounds.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
PrestaShop is an Open Source e-commerce web application. Versions prior to 8.0.4 and 1.7.8.9 contain a SQL filtering vulnerability. A BO user can write, update, and delete in the database, even without having specific rights. PrestaShop 8.0.4 and 1.7.8.9 contain a patch for this issue. There are no known workarounds.

Improper Control of Generation of Code ('Code Injection')
In the orders section of PrestaShop before 1.7.2.5, an attack is possible after gaining access to a target store with a user role with the rights of at least a Salesman or higher privileges. The attacker can then inject arbitrary PHP objects into the process and abuse an object chain in order to gain Remote Code Execution. This occurs because protection against serialized objects looks for a 0: followed by an integer, but does not consider 0:+ followed by an integer.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
PrestaShop is an open source e-commerce web application. Prior to version 8.1.1, the `displayAjaxEmailHTML` method can be used to read any file on the server, potentially even outside of the project if the server is not correctly configured. Version 8.1.1 contains a patch for this issue. There are no known workarounds.

### Patches
8.2.4 and 9.0.3

### Workarounds
none

Improper Privilege Management
PrestaShop is an Open Source e-commerce web application. In the Prestashop Back office interface, an employee can list all modules without any access rights: method `ajaxProcessGetPossibleHookingListForModule` does not check access rights. This issue has been addressed in commit `15bd281c` which is included in version 8.1.2. Users are advised to upgrade. There are no known workaround for this issue.
