CVE-2026-54231: Fedoraproject Fedora

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 43 only; version 44 only
• Red Hat Automatic Bug Reporting Tool: any version
• Red Hat Enterprise Linux: version 7.0 only; version 8.0 only
