WPvivid — Backup, Migration & Staging: Arbitrary database-table deletion
The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137 does not verify that a submitted snapshot identifier names a snapshot it actually created before using it as a database table-name prefix, so an authenticated administrator can supply the site's table prefix, or any other string, and cause the WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137 to drop every matching table, including the core WordPress tables, destroying the site's database. The structured affected range is < 0.9.137.
