Abrt: event handler scripts follow symlinks when writing output files, allowing arbitrary file overwrites_CVE-2026-54230

{
    "lastseen": "",
    "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.",
