CVE-2026-82264
Duplicacy through 3.2.5 contains a path traversal vulnerability in the restore function that fails to validate entry paths deserialized from snapshot files. Attackers can craft malicious snapshot entries with directory traversal sequences to write files outside the restore directory to arbitrary locations accessible by the restoring user.
What the metrics mean
- It is reachable over a network, without needing local access.
- For an attacker who can reach it, exploitation depends on conditions outside the attacker's control.
- To exploit it, no account is needed.
- Beyond that, someone has to be persuaded to take an action first.
