MediaWiki before 1.18.5, and 1.19.x before 1.19.2 saves passwords in the local database, (1) which could make it easier for context-dependent attackers to obtain cleartext passwords via a brute-force attack or, (2) when an authentication plugin returns a false in the strict function, could allow remote attackers to use old passwords for non-existing accounts in an external authentication system via unspecified vectors.

Security readout for executives and security teams

Older MediaWiki releases could keep password data in the local database in ways that weakened external authentication. If exposed, an attacker with the right context might brute-force locally stored passwords or reuse old passwords for accounts no longer present in the external identity system. Exposure is most likely in legacy MediaWiki deployments, especially sites using external authentication plugins and still running before 1.18.5 or 1.19.2. Current or fully upgraded MediaWiki installations are not indicated as affected by the provided sources. Treat this as a legacy-platform risk. It is not presented as actively exploited, but affected systems can weaken identity controls and create credential exposure risk. Prioritize if MediaWiki supports business-critical, internet-facing, or privileged internal workflows. Mitigation focus: Upgrade MediaWiki to at least 1.18.5 or 1.19.2, per affected version boundaries.; Review vendor and distribution advisories for any backported fixes.; Audit external authentication plugin behavior and compatibility..
