CVE-2026-104440

YesWiki before 4.6.7 contains a blind server-side request forgery vulnerability that allows unauthenticated attackers to make arbitrary server-side requests via the idtypeannonce parameter of /api/entries/bazarlist. Because isValidURL() always returns true, attackers can supply internal URLs fetched by curl in loadURLContent() to probe internal networks and reach internal services or metadata endpoints.
