Apache CXF: OAuth2: Log Injection via Unsanitized Client Identifier_CVE-2026-50629

{
    "lastseen": "",
    "description": "The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log warning messages without sanitizing control characters. This allows an attacker to inject arbitrary content, including fake log entries, into the server's log files.\u00a0Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.",
