CVE-2020-35615
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! 2.5.0 through 3.9.22. A missing token check in the emailexport feature of com_privacy 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.

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.
-
Check Joomla versionNavigate to Help > About Joomla in the admin panel, or check the version.php file in the /libraries/cms/version/ directory, or run: grep -r 'RELEASE' /libraries/cms/version/version.phpAffected if Installed version is 2.5.0 through 3.9.22 inclusive
-
Verify com_privacy component statusLog into Joomla admin panel and navigate to Components > Privacy Tool, or check the #__extensions table in the database for com_privacy with enabled=1Affected if com_privacy component is installed and enabled
-
Check emailexport functionality accessAttempt to access the email export feature via the com_privacy component URL structure: /administrator/index.php?option=com_privacy&task=remind.request, or inspect the file /administrator/components/com_privacy/controllers/request.php for missing JSession::checkToken() callsAffected if The emailexport feature is accessible and lacks CSRF token validation in the code
