**Name of the Vulnerable Software and Affected Versions**
EspoCRM version 5.6.4
**Description**
The issue is related to stored XSS due to the lack of filtration of user-supplied data in the Knowledge base. A malicious attacker can inject JavaScript code in the `body` parameter during the "/api/v1/KnowledgeBaseArticle" API endpoint for knowledge-base record creation.
**Recommendations**
For EspoCRM version 5.6.4, as a temporary workaround, consider validating and sanitizing user input for the `body` parameter in the "/api/v1/KnowledgeBaseArticle" API endpoint to prevent JavaScript code injection. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
