Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache SkyWalking apm-webapp up to 10.1.0 is listed as affected, though the description says up to 10.2.0. A stored cross-site scripting flaw lets injected script run in a web page, and the source gives few details on what access an attacker needs. Upgrade to 10.3.0, which was not yet on Maven at publication.
