Machine-written summary

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

GeoServer (gs-web-app and gs-web-sec-core, Maven) versions 2.27.0 up to 2.27.3 and versions below 2.26.4 are affected. An authenticated administrator with access to GeoServer's security system can pass an absolute file path to the Master Password Dump page and write the master password in plaintext to that file, which can lead to code execution if a JSP file is written to a location the server serves. Upgrade to 2.27.3 or 2.26.4. Installations with the web interface disabled or removed are not affected.
