This vulnerability allows a remote attacker to perform an arbitrary file write outside the intended destination directory. By crafting a malicious zip archive containing a symbolic link (symlink) and a regular file with the same name, the attacker can bypass security checks. The extract-zip utility incorrectly validates only the parent directory, enabling the attacker to write files to arbitrary locations on the system.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Node HealthCheck Operator, OpenShift Pipelines, Red Hat Build of Podman Desktop, Red Hat Ceph Storage 4, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, … · no fix planned: Red Hat Build of Podman Desktop, Red Hat Fuse 7, Node HealthCheck Operator, OpenShift Pipelines, … · updated 2026-09-09 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-19693.json)\n\n**extract-zip: extract-zip: Arbitrary file write via symlink in archive** — rated Important by Red Hat.
