CVE ID :CVE-2026-54230

Published : June 13, 2026, 3:16 a.m. | 33 minutes ago

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.

Severity: 7.0 | HIGH
