CVE-2026-54231

Content injection via unsanitized journal output

Published Jun 13, 2026 · Updated Jun 13, 2026

Content injection in ABRT on Red Hat Enterprise Linux 7 and 8 allows local users to control root-written dump-file content via syslog. The post-create scripts query journalctl with _COMM and _UID filters, then copy entries into dump-directory files without removing embedded newlines or validating the resulting lines. Exploitation requires local access and an installed, running ABRT service; it alters diagnostic-file integrity without reported disclosure or service interruption.
