CVE-2015-8563
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 · uneditedCross-site request forgery (CSRF) vulnerability in the com_templates component in Joomla! 3.2.0 through 3.3.x and 3.4.x before 3.4.6 allows remote attackers to hijack the authentication of unspecified victims via unknown vectors.
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 · moderate confidenceCross-site request forgery (CSRF) vulnerability in Joomla's com_templates component allows remote attackers to forge requests on behalf of authenticated users. The vulnerability stems from missing or insufficient anti-CSRF tokens in the template management functionality, enabling attackers to trick authenticated administrators into performing unintended template configuration changes.

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.
-
Identify installed Joomla versionLog into the Joomla administrator backend and navigate to Help > System Info > Version, or check the VERSION constant in /libraries/cms/version/version.phpAffected if The version shown is any of: 3.2.0, 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.3.0, 3.3.1, 3.3.2, 3.3.3, 3.3.4, 3.3.5, or 3.4.0
-
Confirm administrator access to template managerNavigate to Extensions > Templates in the administrator panel to verify the com_templates component is accessibleAffected if Authenticated administrators have access to the template management interface in an affected Joomla version
-
Verify CSRF token absence in template formInspect the HTML source of any template editing page in Extensions > Templates > Templates. Check if the form includes a hidden input with name token or a csrf.token valueAffected if No anti-CSRF token field is present in template management forms (the form lacks token validation)
-
Check for active session usageConfirm that administrators are using active sessions in the affected version, as the attack requires a logged-in administratorAffected if Administrators have active sessions while using affected Joomla versions
You are affected if running any Joomla version between 3.2.0 and 3.4.0 inclusive and administrators can access the template manager component.

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 dataUpdate Joomla to version 3.4.6 or later, which includes proper CSRF token validation in the com_templates component. Additionally, implement SameSite cookie attributes and verify referrer headers as defense-in-depth measures.
