A flaw has been found in Sanluan PublicCMS 5.202506.d. The impacted element is the function execute of the file publiccms-core/src/main/java/com/publiccms/views/directive/tools/TemplateResultDirective.java of the component templateResult API. This manipulation of the argument templateContent causes improper neutralization of special elements used in a template engine. The attack is possible to be carried out remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
