description

YesWiki versions through 4.6.6 allow the autoupdate action to delete installed extensions without CSRF validation. An attacker can induce deletion of an extension and disrupt site functions if a logged-in administrator follows a malicious link.

mitigation

Upgrade the composer package yeswiki/yeswiki to version 4.6.7. Until upgraded, restrict administrator access to the autoupdate page and avoid following untrusted links while authenticated.

fixed in 4.6.7
