The response coming from TP-Link Archer MR200 v5.2, C20 v5 and v6, TL-WR850N v3, and TL-WR845N v4 for any request is getting executed by the JavaScript function like eval directly without any check. Attackers can exploit this vulnerability via a Man-in-the-Middle (MitM) attack to execute JavaScript code on the router's admin web portal without the user's permission or knowledge.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.6, indicating it can be exploited remotely over the network but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts limited data confidentiality, limited integrity, and limited availability for affected systems. Impacting 8 products from tp-link, from tp-link, from tp-link and 5 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For tp-link's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
