Each source scores the same vulnerability from what it judges the attack to need. The rows marked are where they judge it differently.

Timeline

2026-05-04	first spoke of it: abrt: event handler scripts follow symlinks when writing output files, allowing arbitrary file overwrites	Red Hat
2026-06-13	first spoke of it: 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.	NVD
