Description
CVE-2026-12605 is a critical vulnerability in Eclipse GlassFish versions 8.0.0 before 8.0.4. It involves a combination of CSRF and SSRF vulnerabilities in the DownloadServlet ContentSources that can leak the admin gfresttoken to an attacker-controlled host if the victim is authenticated in the Admin Console. This leakage allows an unauthenticated attacker to fully take over the Eclipse GlassFish domain until the token expires.
