CVE-2026-13339Network attack vector

Unauthenticated file read via uncontained icon paths

Published Aug 1, 2026 · Updated Aug 1, 2026

Path traversal in CubeWP Framework 1.1.30 and earlier allows remote attackers to read arbitrary server files through crafted icon paths. The cubewp_get_svg_content function converts attacker-controlled prev_icon or next_icon URLs into filesystem paths and passes them to file_get_contents without canonicalizing or confining the resolved path. Exploitation requires a page using the CubeWP posts shortcode or widget with AJAX loading enabled, where the required nonce is exposed to guest visitors; successful requests disclose files readable by PHP.
