The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.133 does not validate the destination of files extracted from a backup package during restoration, allowing high privilege users such as administrators to write arbitrary files outside the intended restore directory, which can lead to code execution.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.6, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction . The vulnerability impacts limited data confidentiality, limited integrity, and limited availability for affected systems.
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 affected software, 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.
