Description
This security bulletin contains information about 2 vulnerabilities.
1) CRLF injection (CVE-ID: CVE-2025-25184)
CWE-ID: CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')
CVSSv4: CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to manipulate data log entries.
