Deeper analysis
The Migration, Backup, Staging WordPress plugin before version 0.9.76 contains a path traversal flaw (CWE-22) in which a parameter is used to read file contents without prior sanitization or validation. The issue affects the plugin's file-handling routines and carries a CVSS 4.9 rating that reflects network attack vector, low complexity, and high-privilege requirements while impacting only confidentiality.
High-privilege users such as administrators can supply a crafted parameter to traverse the file system and retrieve arbitrary files stored on the web server. Publicly available proof-of-concept material demonstrates the attack against the WPvivid Backup component.
EPSS for the CVE rose from a low baseline to a peak of 0.5560 on 2025-01-22 before receding to the current value of 0.1089, indicating that exploitation interest increased well after the original disclosure. References such as WPScan and Packet Storm list detailed traversal payloads that confirm the issue is reproducible in vulnerable installations.
