Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache JSPWiki (jspwiki-main and jspwiki-markdown) versions before 2.12.3 are vulnerable to cross-site scripting through header link rendering in the wiki markup and markdown parsers. An attacker can send a specially crafted request when a header link is created, which could run JavaScript in a victim's browser and expose some sensitive information. Users should upgrade to version 2.12.3 or later.
