Security readout for executives and security teams
Plain-English summary
CVE-2019-14350 is a reported stored cross-site scripting issue in EspoCRM 5.6.4 Knowledge Base articles. An attacker who can create a knowledge-base record may place JavaScript in article content, which could run later in another user’s browser.
Executive priority
Treat this as a contained but meaningful application-security issue. Prioritize systems where CRM users include external parties, contractors, or broad internal audiences, because stored XSS can turn trusted CRM content into a browser-side attack surface.
Technical view
The source describes insufficient filtering of user-supplied data in EspoCRM 5.6.4 Knowledge Base. The vulnerable input is the article body parameter during api/v1/KnowledgeBaseArticle record creation, resulting in stored XSS. No CVSS, CWE, patch version, or complete affected-product metadata is provided.
Likely exposure
Likely exposure is EspoCRM 5.6.4 deployments where Knowledge Base article creation is enabled, especially if non-admin or less-trusted users can create content. The bundle does not identify other affected versions.
Exploitation context
The CVE is not marked as KEV, and the supplied sources do not show active exploitation. The public evidence describes a stored XSS condition, but does not provide reliable exploit-in-the-wild status.
Researcher notes
Evidence is limited to the CVE description and linked GitHub issue. The bundle lacks CVSS, CWE, fixed-version, and affected-version range details. Avoid broad version claims without confirming EspoCRM release history or vendor advisories.
Mitigation direction
- Check EspoCRM vendor guidance and the linked issue for fixed versions.
- Upgrade from EspoCRM 5.6.4 if a vendor-supported fixed release is available.
- Restrict Knowledge Base article creation to trusted roles only.
- Review existing Knowledge Base article bodies for suspicious script content.
- Consider compensating controls that sanitize or block unsafe HTML input.
Validation and detection
- Inventory EspoCRM instances and confirm deployed versions.
- Identify whether Knowledge Base functionality is enabled.
- Review roles allowed to create Knowledge Base articles.
- Inspect recent article body content for unexpected JavaScript or unsafe HTML.
- Confirm vendor guidance or release notes for remediation status.
