Short explanation

Kopia through version 0.23.1 contains a path traversal vulnerability within copyDirectoryContent, allowing users with repository write access to escape the restore directory via crafted entry names (S0).

Why does it matter?

When victims perform a restore operation using default options, attackers can write custom content outside the intended restore directory, creating integrity risks (S0).

What should be done?

Follow vendor advisories (S0)

Show the technical text from the sources

Kopia through 0.23.1 contains a path traversal vulnerability in copyDirectoryContent that allows users with repository write access to escape the restore directory via crafted entry names. Attackers can create snapshots whose directory manifest entries are named '..', so victims restoring with default options write attacker-chosen content outside the restore directory.
