Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions of github.com/lf-edge/ekuiper/v2 before 2.4.0 are affected by a cross-site scripting flaw in external service creation: service names were not strictly checked for alphanumeric characters, so HTML or script could be stored in a name. An authenticated attacker with API access can register such a name, and it may run in a user's browser when an administrative web interface renders it unescaped. Upgrade to version 2.4.0 or later, which enforces strict ID validation on these endpoints.
