CVE-2023-27640
Published: April 11, 2026
Official Description
An issue was discovered in the tshirtecommerce (aka Custom Product Designer) component 2.1.4 for PrestaShop. An HTTP request can be forged with the POST parameter type in the /tshirtecommerce/fonts.php endpoint, to allow a remote attacker to traverse directories on the system in order to open files (without restriction on the extension and path). The content of the file is returned with base64 encoding. This is exploited in the wild in March 2023.
Technical Analysis
CVE-2023-27640 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2023-27640 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
