Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache JSPWiki (org.apache.jspwiki:jspwiki-main) versions before 2.12.3 are vulnerable to cross-site scripting through the Image plugin. An attacker can send a specially crafted request that causes JavaScript to run in a victim's browser, potentially exposing sensitive information about the victim. Users should upgrade to version 2.12.3 or later.
