Description
This security bulletin contains information about 1 vulnerability.
1) CRLF injection (CVE-ID: CVE-2026-12357)
CWE-ID: CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to inject arbitrary data in server response.
The vulnerability exists due to insufficient validation of attacker-supplied data within the generateFileContent function. A remote administrator can pass specially crafted data to the application containing CR-LF characters and modify application behavior, leading to arbitrary code execution.
