What is CVE-2026-104442?

YesWiki prior to version 4.6.7 is susceptible to an unauthenticated server-side request forgery (SSRF) vulnerability. By manipulating the syndication action through the render handler's content parameter, remote attackers can instruct the server to retrieve arbitrary URLs. This vulnerability poses significant risks as it can allow attackers to access internal hosts and ports, exfiltrate feed content, and lead to unauthorized file downloads within the server’s directory. Organizations using affected versions are recommended to upgrade to the latest version to mitigate potential exploitation.
