CVE-2019-18650
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in Joomla! before 3.9.13. A missing token check in com_template causes a CSRF vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA Cross-Site Request Forgery (CSRF) vulnerability in Joomla! before version 3.9.13 exists due to a missing anti-CSRF token validation in the com_template component. This allows attackers to trick authenticated administrators into unknowingly executing unwanted actions within the template management interface.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed Joomla! versionNavigate to the Joomla! administrator dashboard and check the version information, typically found in the Help > System Information menu or in the libraries/cms/version.php fileAffected if The installed version falls within >= 3.2.0 and <= 3.9.12
-
Verify com_template component existsCheck if the /administrator/components/com_template/ directory exists in the Joomla installationAffected if The com_template component is installed and present in the system
-
Confirm administrator access to template managerLog in as an administrator and navigate to Extensions > Templates to confirm access to the template management interfaceAffected if Authenticated administrators can access the template management area
-
Inspect com_template for CSRF token validationExamine the controller or model files in the com_template component (such as controller.php or any style/task files) for the presence of JSession::checkToken() or similar CSRF token validation callsAffected if The code lacks proper CSRF token validation (JSession::checkToken or equivalent) in template-related operations
A user is affected if their Joomla! installation version is between 3.2.0 and 3.9.12 inclusive and the com_template component lacks CSRF token validation in its code.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Joomla! 3.9.13 or later which includes the missing token check. If immediate upgrade is not possible, implement CSRF tokens in the com_template component or enforce additional authentication checks for template-related operations.
