Overview
CVE-2025-47535 is a critical vulnerability that resides in the wpopal Opal Woo Custom Product Variation software. This vulnerability, categorized as “Path Traversal”, could allow an attacker to access files and directories that are outside of the web root folder. By manipulating variables that reference files with “dot-dot-slash (../)” sequences and its variations, attackers can navigate the filesystem and potentially compromise the system or leak data.
This vulnerability is of high importance due to the potential damage it could cause. Entities that utilize wpopal Opal Woo Custom Product Variation from version n/a through 1.2.0 are at risk and should take immediate steps to mitigate the threat.

How the Exploit Works
The vulnerability resides in the way wpopal Opal Woo Custom Product Variation handles file and directory paths. By exploiting this vulnerability, an attacker can send specially crafted requests containing “dot-dot-slash (../)” sequences to the application. This allows the attacker to navigate the server’s directory structure, accessing potentially sensitive files outside of the intended directory. The vulnerability could be used to read, write, or delete data, depending on the permissions of the application.
Conceptual Example Code
This conceptual example demonstrates how an attacker might take advantage of the vulnerability:
GET /file?filename=../../../etc/passwd HTTP/1.1
Host: target.example.comIn this example, the attacker attempts to exploit the Path Traversal vulnerability to read the passwd file, which could expose sensitive system information.
Mitigation and Prevention
The most effective way to mitigate this vulnerability is to apply the vendor patch. Entities that are unable to apply the patch immediately can use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation strategy. Additionally, it is recommended to limit the privileges of the application to the absolute minimum required for its operation, to further limit the potential impact of a successful exploit.
