CVE-2026-54231: Abrt: unsanitized systemd journal content written to dump directory files enables content injection

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: abrt (AlmaLinux:8) 2.10.9-26.el8_10.alma.1; abrt-addon-ccpp (AlmaLinux:8) 2.10.9-26.el8_10.alma.1; abrt-addon-coredump-helper (AlmaLinux:8) 2.10.9-26.el8_10.alma.1.

Low priority for now. Upgrade to abrt (AlmaLinux:8) 2.10.9-26.el8_10.alma.1; abrt-addon-ccpp (AlmaLinux:8) 2.10.9-26.el8_10.alma.1; abrt-addon-coredump-helper (AlmaLinux:8) 2.10.9-26.el8_10.alma.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
