CVE-2011-1133
Cross-Site Scripting (XSS) in Xinha, as included in the Serendipity package before 1.5.5, allows remote attackers to execute arbitrary code via plugins/ExtendedFileManager/backend.php.
Does this matter?
Lower severity and a low EPSS score (1.77%). Track it; it rarely justifies an emergency change on its own.
