Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
YesWiki versions before 4.6.6 (Packagist yeswiki/yeswiki) are affected by SQL injection through the period argument of the recentchanges action. An attacker who can save a page containing the action with a crafted period value can read arbitrary database content, and the leaked data appears in the page for any visitor; on default installs anonymous users may be able to save such a page. Upgrade to version 4.6.6 or later. The source gives no workaround.
