Auchan Retail Global Score (TPRM)XXXX

Description: French retail giant Auchan suffered a cyberattack in August 2025, resulting in the theft of loyalty account data from several hundred thousand customers. Attackers accessed personal information, including names, postal/email addresses, phone numbers, and loyalty card numbers, though financial data (bank details, PINs, and loyalty balances) remained secure. The breach was detected and contained promptly, with notifications sent to affected customers and France’s data protection authority (CNIL). This marks Auchan’s second major breach in a year, following a similar November 2024 incident targeting loyalty program data. While no passwords or payment credentials were compromised, the stolen data poses risks for targeted phishing attacks or underground sale. Auchan has implemented multi-factor authentication, enhanced network monitoring, and employee cybersecurity training, alongside offering free credit monitoring to impacted customers. Authorities are investigating the attack’s origin, while consumers are warned to stay vigilant against fraudulent communications.

Typemill is a flat-file, Markdown-based CMS designed for informational documentation websites. A reflected Cross-Site Scripting (XSS) exists in the login error view template `login.twig` of versions 2.19.1 and below. The `username` value can be echoed back without proper contextual encoding when authentication fails. An attacker can execute script in the login page context. This issue has been fixed in version 2.19.2.
A DOM-based Cross-Site Scripting (XSS) vulnerability exists in the DomainCheckerApp class within domain/script.js of Sourcecodester Domain Availability Checker v1.0. The vulnerability occurs because the application improperly handles user-supplied data in the createResultElement method by using the unsafe innerHTML property to render domain search results.
A Remote Code Execution (RCE) vulnerability exists in Sourcecodester Modern Image Gallery App v1.0 within the gallery/upload.php component. The application fails to properly validate uploaded file contents. Additionally, the application preserves the user-supplied file extension during the save process. This allows an unauthenticated attacker to upload arbitrary PHP code by spoofing the MIME type as an image, leading to full system compromise.
A UNIX symbolic link following issue in the jailer component in Firecracker version v1.13.1 and earlier and 1.14.0 on Linux may allow a local host user with write access to the pre-created jailer directories to overwrite arbitrary host files via a symlink attack during the initialization copy at jailer startup, if the jailer is executed with root privileges. To mitigate this issue, users should upgrade to version v1.13.2 or 1.14.1 or above.
An information disclosure vulnerability exists in the /srvs/membersrv/getCashiers endpoint of the Aptsys gemscms backend platform thru 2025-05-28. This unauthenticated endpoint returns a list of cashier accounts, including names, email addresses, usernames, and passwords hashed using MD5. As MD5 is a broken cryptographic function, the hashes can be easily reversed using public tools, exposing user credentials in plaintext. This allows remote attackers to perform unauthorized logins and potentially gain access to sensitive POS operations or backend functions.
