This repository provides a proof-of-concept (PoC) exploit for CVE-2022-0165, a vulnerability in the KingComposer Page Builder WordPress plugin (versions up to 2.9.6). The vulnerability allows an attacker to bypass validation of the 'id' parameter in the kc_get_thumbn AJAX action, potentially leading to open redirection attacks. The repository contains a Bash script (CVE-2022-0165.sh) that takes a target URL as input, appends the vulnerable endpoint, and uses curl to check for a redirect location in the response headers. The README.md provides detailed background, exploitation steps, and mitigation advice. The exploit demonstrates the vulnerability but does not provide weaponized or automated attack capabilities beyond basic validation and demonstration.
