info:
  name: Adminer <=4.8.0 - Cross-Site Scripting
  author: daffainfo
  severity: medium
  description: Adminer 4.6.1 to 4.8.0 contains a cross-site scripting vulnerability which affects users of MySQL, MariaDB, PgSQL, and SQLite in browsers without CSP when Adminer uses a `pdo_` extension to communicate with the database (it is used if the native extensions are not enabled).
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into the Adminer interface, potentially leading to session hijacking, defacement, or theft of sensitive information.
  remediation: This 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`).
