Machine-written summary

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

Versions of org.owasp.esapi:esapi before 2.6.0.0 have a Validator.isValidSafeHTML method that can return true for input that is not actually safe, so using that input as-is can in some cases lead to cross-site scripting. The source gives few details on the exact conditions an attacker needs. Upgrade to esapi 2.6.0.0 or later, where the method has been removed. Until then, stop using isValidSafeHTML; Validator.getValidSafeHTML is believed to be safe with the default antisamy-esapi.xml policy.
