Redhat Automatic Bug Reporting Tool
CVE-2026-54231
A content injection vulnerability was found in the ABRT post-create event handler scripts in libreport. The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded control characters. A local user can inject arbitrary content into the journal output by embedding newline characters in syslog messages, controlling the content that root writes to dump directory files.
