A flaw was found in BusyBox. When extracting an archive, the tar utility improperly resolves deferred hardlink targets across symbolic links pointing outside the intended extraction directory. An attacker could provide a specially crafted archive that links to sensitive files outside the extraction tree, allowing subsequent extraction operations to overwrite arbitrary files on the system.

CVE-2026-126859——
———Link following in FileSystem in Google Chrome prior to 157.0.8103.78 allowed a remote attacker leveraging social engineering to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)2hCVE-2026-911517.3 ALT—
———A flaw was found in Cockpit. A local authenticated user with control over a target account's home directory can exploit a privileged symlink dereference vulnerability in the `ssh-add-public-key.sh` helper. When this helper runs with elevated privileges, it can be tricked into following attacker-controlled symlinks within the `.ssh` or `authorized_keys` paths. This allows the attacker to arbitrarily change file ownership and modes, potentially leading to local privilege escalation and impacting the integrity, confidentiality, and availability of the system.5hCVE-2026-1247446.3 MÉD—
———A flaw was found in BusyBox. When extracting files using the cpio utility with path traversal protection enabled, hardlink target paths are not properly sanitized. By tricking a user or automated process into extracting a crafted archive, an attacker can create hardlinks that point to files outside the intended extraction directory. This issue may allow an attacker to modify or overwrite arbitrary files outside the target directory during subsequent extraction operations.12hCVE-2026-124495——
———When workers run as the topology owner, the Logviewer serves files that a worker has placed in its own log directory as links to other files. A user who is allowed to submit topologies can read the worker logs of other users' topologies, and other files the Logviewer process can read. Users are recommended to upgrade to version 3.2.0, which fixes the issue.6hCVE-2026-1266127.8 ALT4.8%
——1Improper link resolution in the Windows installer of Progressive Robot hMailServer 6.0.0 through 6.3.7 allows a local authenticated user to run code as the mail server's service account or as an administrator when the path to the program folder passes through a junction, a symbolic link or a mount point that the user controls or that every user may change, such as a junction made at the root of a drive, which takes the root's permissions, or through a folder that every user may rename. Setup installed the programs through any such link without first checking who controls it, or whether a folder above the program folder may be renamed, and the service is registered to run the programs by that path, so the programs are installed where a link another account controls leads, or that account can later make the path lead to a folder it controls; the service, which runs as LocalSystem or as its virtual account, and the programs administrators run from Bin are then started from there. 6.3.7's fix for CVE-2026-107571 does not cover this: its hardening of the program folder, Bin and ControlPanel does not change a folder reached through a link that the administrators do not alone control, and setup does not refuse such a path: it installs through the link and at most reports afterwards that the folders could not be hardened. The default installation under Program Files is not affected.16hCVE-2026-959637.8 ALT32.3%
