What is CVE-2026-108156?
CVE-2026-108156 is a medium-severity path traversal vulnerability in netease-youdao LobsterAI, published on 9 Oct 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
LobsterAI 2026.5.27 through 2026.9.23 contains an external control of file path vulnerability in the skills:delete IPC handler that trusts the openclawSourceDir value from a skill's _meta.json during uninstall. Attackers who convince a user to install a crafted skill can make uninstallation recursively delete arbitrary user-writable directories, such as the home directory, since the security scanner never inspects _meta.json.
Weakness: CWE-73
