CVE-2026-101885
ZeroClaw versions before 0.8.5 built with plugins-wasm feature contain a path traversal vulnerability in plugin installation that fails to validate the wasm_path manifest field.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
ZeroClaw versions before 0.8.5 built with plugins-wasm feature contain a path traversal vulnerability in plugin installation that fails to validate the wasm_path manifest field. Attackers can convince users to install crafted plugins that write arbitrary files to paths outside the plugins directory, such as shell startup files, enabling code execution.
