Absolute Path Traversal vulnerability in AP Page Builder versions prior to 4.0.0

Disclosed: 08.05.2025
Updated: 11.10.2026 10:22

Ap Page Builder is vulnerable to an absolute path traversal that allows the attacker to include system files by modifying the base64 config param submitted to apajax.php

Absolute Path Traversal vulnerability in AP Page Builder versions prior to 4.0.0 could allow an unauthenticated remote user to modify the ‘product_item_path’ within the ‘config’ JSON file, allowing them to read any file on the system.

WARNING : This exploit uses a Base64 payload, which may bypass most WAFs.

Be aware that it’s possible to obfuscate a Base64 string using special characters to evade detection - the base64_decode() function in PHP will silently strip them out.

For example, the following is a perfectly valid Base64 input for base64_decode: Li4$vLi4-vY#XBwL–2NvbmZpZy9wYXJhb-WV0Z$XJzLnB$ocA==

If you’re using ModSecurity 2, prefer base64DecodeExt over base64Decode to mitigate this technique.
