Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
