In recent cybersecurity news, a significant vulnerability has been discovered in the TI WooCommerce Wishlist plugin for WordPress, which has more than 100,000 active installations. This critical flaw allows unauthenticated attackers to upload arbitrary files to the server, posing a serious threat to websites running the plugin. As the plugin does not currently have an available patch, it’s important for users to understand the risks involved and take immediate action.
Overview of the Vulnerability
The TI WooCommerce Wishlist plugin is a popular tool that enables e-commerce site customers to save their favorite products for later and share the lists on social media. However, this functionality has an unexpected downside—an arbitrary file upload vulnerability that enables unauthorized attackers to upload malicious files without needing to authenticate.
Security researchers from Patchstack, including John Castro, revealed that this vulnerability is tracked as CVE-2025-47577 and has received a critical CVSS score of 10.0. This flaw affects all versions of the plugin below and including version 2.9.2, released on November 29, 2024. Unfortunately, no patch has been issued for this issue yet, leaving websites vulnerable.
The flaw lies in a function within the plugin called “tinvwl_upload_file_wc_fields_factory,” which uses a native WordPress function, “wp_handle_upload,” to perform file validation. However, the validation is bypassed due to incorrect settings for two parameters—”test_form” and “test_type.” Specifically, both are set to “false,” allowing any type of file to be uploaded, regardless of whether it is harmful or not.
Further complicating the issue, the vulnerable function can be accessed through “tinvwl_meta_wc_fields_factory” or “tinvwl_cart_meta_wc_fields_factory,” which are only available if the WC Fields Factory plugin is also installed and active. This means that successful exploitation of the flaw is contingent on both plugins being present and integrated.
If exploited, attackers could upload a malicious PHP file, leading to remote code execution (RCE), which grants them full control over the server. This opens the door for a variety of attacks, including data theft, website defacement, or complete server compromise.
Until the developers release a patch, security experts recommend that users deactivate and delete the TI WooCommerce Wishlist plugin from their websites to prevent potential exploitation.
What Undercode Says: Understanding the Impact and Response
The severity of this vulnerability cannot be understated. A CVSS score of 10.0 indicates a critical security flaw that can have catastrophic consequences if exploited. The ability to upload arbitrary files to a server without authentication is a well-known attack vector for cybercriminals, and in this case, the flaw in the TI WooCommerce Wishlist plugin significantly lowers the barrier for entry.
The fact that the vulnerability requires the integration of the WC Fields Factory plugin may offer a small degree of mitigation, but it does not eliminate the risk. The widespread use of these two plugins together on e-commerce websites means that the attack surface remains vast.
From a cybersecurity perspective, the situation is worrying, as the vulnerability allows for remote code execution, one of the most dangerous outcomes of a successful exploit. Attackers could potentially execute arbitrary code on the server, giving them the ability to exfiltrate sensitive data, manipulate website content, or even take full control of the server for further malicious actions.
The absence of a patch increases the urgency for website administrators to take action. Deactivating or deleting the plugin is the most effective way to mitigate the risk, but it also leaves e-commerce sites without a key functionality—making the situation even more challenging for business owners.
Fact Checker Results: Key Insights
Severity: The vulnerability is classified with a CVSS score of 10.0, meaning it’s extremely critical.
Exploitability: Attackers do not need authentication to exploit this vulnerability, increasing the likelihood of abuse.
Mitigation: The lack of a patch and the need for both the TI WooCommerce Wishlist and WC Fields Factory plugins to be active are factors to consider in evaluating risk.
Prediction: What Could Happen Next?
As cybersecurity experts continue to investigate this vulnerability, it is likely that new details will emerge regarding potential attack vectors and exploitation techniques. However, one of the most pressing concerns is the delay in issuing a patch for the flaw. If a patch is not released soon, it’s possible that cybercriminals will begin targeting websites that rely on these plugins, leading to a wave of attacks.
In the meantime, e-commerce site administrators should stay vigilant and implement security measures, such as disabling the vulnerable plugins, to protect their websites from the growing threat. The situation also highlights the importance of regular security updates and proactive vulnerability management for all WordPress users.
