    CVE-2026-92775

    Wiki.js through 2.5.314 contains a server-side request forgery vulnerability in the Image Prefetch renderer that fetches arbitrary URLs without protocol, host, or address validation. Attackers with page editing permissions can inject img elements with the prefetch-candidate class to make the server request internal services and cloud metadata endpoints, with responses returned to the attacker.
