Detailsinfo

A vulnerability was found in gopasspw gopass up to 1.16.x. It has been rated as problematic. This issue affects the function Prune/IsDir of the component Filesystem Storage Backend.

Impacted is integrity, and availability. The summary by CVE is:

gopass before 1.17.0 contains a path traversal vulnerability in the filesystem storage backend that allows attackers to delete directories outside the password store via ../ entry names in Prune and IsDir. Collaborators with write access to a shared git-synced store can introduce crafted entries, causing a victim's recursive gopass rm -r to delete arbitrary directory trees.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-118756 since 10/28/2026. The exploitation is known to be easy. The attack may be initiated remotely.
