CVE-2022-47927

Name of the Vulnerable Software and Affected Versions MediaWiki versions prior to 1.35.9 MediaWiki versions 1.36.x through 1.38.x before 1.38.5 MediaWiki versions 1.39.x before 1.39.1

Description An issue was discovered in MediaWiki when installing with a pre-existing data directory that has weak permissions. The SQLite files are created with file mode 0644, making them world-readable to local users. These files include credentials data.

Recommendations For MediaWiki versions prior to 1.35.9, update to version 1.35.9 or later. For MediaWiki versions 1.36.x through 1.38.x before 1.38.5, update to version 1.38.5 or later. For MediaWiki versions 1.39.x before 1.39.1, update to version 1.39.1 or later. As a temporary workaround, consider restricting access to the SQLite files to minimize the risk of exploitation.
