Vulnerability description
DayBreach CVE AI Research
CVE-2026-62947 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
