CVE-2025-48388 (GCVE-0-2025-48388)

Vulnerability from cvelistv5 – Published: 2025-05-29 09:16 – Updated: 2025-05-29 13:39

Title

FreeScout Has Insufficient Protection Against CRLF-injection

Summary

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.178, the application performs insufficient validation of user-supplied data, which is used as arguments to string formatting functions. As a result, an attacker can pass a string containing special symbols (\r, \n, \t)to the application. This issue has been patched in version 1.8.178.
