CVE-2021-29625

Adminer is open-source database management software. A cross-site scripting
vulnerability in Adminer versions 4.6.1 to 4.8.0 affects users of MySQL,
MariaDB, PgSQL and SQLite. XSS is in most cases prevented by strict CSP in
all modern browsers. The only exception is when Adminer is using a pdo_
extension to communicate with the database (it is used if the native
extensions are not enabled). In browsers without CSP, Adminer versions
4.6.1 to 4.8.0 are affected. The vulnerability is patched in version 4.8.1.
As workarounds, one can use a browser supporting strict CSP or enable the
native PHP extensions (e.g. mysqli) or disable displaying PHP errors
(display_errors).
