CVE-2026-108156
LobsterAI 2026.5.27 through 2026.9.23 Arbitrary Directory Deletion via Skill _meta.json
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.
