Machine-written summary

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

AntiSamy (org.owasp.antisamy:antisamy) versions before 1.7.5 are vulnerable to mutation cross-site scripting when the preserveComments directive is enabled in the policy file. An attacker who can supply crafted input can cause elements inside comments to be interpreted as executable in the sanitized output. Upgrade to AntiSamy 1.7.5 or later; if that is not possible, set preserveComments to false or remove it from the policy file.
