CVE-2023-51333Public exploitNetwork attack vector

Code execution via unneutralized CSV formulas

Published Feb 20, 2025 · Updated Nov 4, 2025

CSV injection in PHPJabbers Cinema Booking System 1.0 allows remote authenticated users to execute code through exported language labels. The Languages section accepts formula-leading text in System Options label parameters and writes it to a CSV file without neutralization. Low-privilege access to that interface is required, and the injected formula runs when the generated file is opened in a spreadsheet application.
