  • CVSS score 9.8: 9.0 or more.
  • CVSS score 9.8 (7.0 or more) and EPSS 1.00 (0.1 or more): a high score and a real chance of exploitation in the next 30 days.

Machine-written summary

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

GeoServer versions from 2.22.0 through the fixed releases are affected, including gs-web-app, gs-wfs and gs-wms, fixed in 2.22.6, 2.23.6, 2.24.4 and 2.25.2. An unauthenticated attacker can send specially crafted OGC requests, such as WFS, WMS or WPS requests, to execute arbitrary code on a default installation. Upgrade to 2.22.6, 2.23.6, 2.24.4, 2.25.2 or a later fixed release. If upgrading is not possible, the source describes removing the gt-complex jar, which may break some functionality.
