Machine-written summary

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

GeoNetwork versions from 3.0.0 through 3.12.12, 4.0.0-alpha.1 through 4.0.6, 4.2.0 before 4.2.15, and 4.4.0 before 4.4.10 are affected. A user who opens a crafted link to a nonexistent or unauthorized service URL can have attacker-controlled text evaluated as an AngularJS template, enabling script execution in the victim's authenticated session. Upgrade to 4.2.15 or 4.4.10; the 3.x and 4.0.x lines are unmaintained and will not receive a fix.
