Sources and claim methodology

  • Source referencevulncheck.com
Upstream source description

YesWiki before 4.6.7 contains a server-side request forgery vulnerability that allows unauthenticated attackers to make server-side GET requests by supplying an unvalidated actor URL to the Bazar abonnements sync action. Attackers can target internal hosts or cloud metadata endpoints and chain attacker-controlled outbox first/next links, with fetched responses stored as readable Bazar entries.
