CVE-2026-55567 BleachBit: Exploit File Delete to Escalate Privilege

BleachBit cleans files to free disk space and to maintain privacy. Prior to 6.0.1, privileged Windows cleaning does not lock and validate a target's parent directory before deletion. A local unprivileged user can replace that directory with a Windows junction and use a native symlink to redirect...

BIT-PYTHON-MIN-2026-82049 tarfile extraction filters allow file modification and content disclosure via hard link to symlink

In CPython 3.13 and earlier, the tarfile module's data and tar extraction filters are vulnerable to crafted archives containing a hard link to a symbolic link. Such archives may cause extraction to modify the permissions or modification time of a file outside the destination directory, or expose...

abrt: event handler scripts follow symlinks when writing output files, allowing arbitrary file overwrites

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 ONOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and...

libvirt: swtpm privilege escalation via symlink following

A flaw was found in libvirt. A local attacker, specifically a process running as the confined swtpm user, could exploit a symlink-following vulnerability in the virFileChownFiles function. By planting a symbolic link within the swtpm state directory, the attacker could trick the root-level libvir...
