CVE-2026-15626Public exploitNetwork attack vector

Authenticated host-file overwrite via dangling symlink

Published Jul 14, 2026 · Updated Jul 14, 2026

Path traversal in GoClaw 3.13.3-beta.3 allows remote authenticated users to write files outside the ACP workspace via a symlink. resolvePath accepts the lexical in-workspace path when EvalSymlinks fails, after which writeFile passes it to os.WriteFile, which follows the dangling link. Exploitation requires an ACP-backed agent session, permission to create the link and write files, and a host target writable by the GoClaw service account.
