Description
OpenWrt is a Linux operating system targeting embedded devices. Prior to 25.12.5, the cgi-download handler in cgi-io authorizes the requested path against the caller's ubus session file ACL before canonicalization, and rpcd session.c uses fnmatch() without FNM_PATHNAME, allowing traversal such as an allowed wildcard prefix followed by ../ to read root-readable files including /etc/shadow. This vulnerability is fixed in 25.12.5.
