Aug 13 RESCORED — CVE-2026-54230 (Red Hat Enterprise Linux 8). CVSS 7 → 7.8 (NVD).
Description
A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary file overwrites on the system.
