Contributor Cross Site Scripting (XSS) in Ghost Kit <= 3.6.0 versions.
AnalysisAI
Cross-site scripting in the Ghost Kit WordPress plugin (versions ≤ 3.6.0) allows authenticated Contributor-level users to inject and store malicious JavaScript payloads via plugin block fields or parameters. When a higher-privileged user - such as an editor or administrator - views the affected content, the attacker's script executes in that user's browser context, enabling session hijacking, credential theft, or unauthorized administrative actions. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold an active, authenticated Contributor-level (or higher) WordPress account on the target site - this is the primary gating condition and the most significant limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.5 (Medium) is grounded in a network-exploitable, low-complexity attack path (AV:N/AC:L) that requires Contributor-level authentication (PR:L) and victim interaction (UI:R), with a scope change (S:C) reflecting cross-user browser impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker holding a Contributor-level WordPress account on the target site crafts a post or page embedding a Ghost Kit block with a malicious JavaScript payload injected into an unsanitized field. When a site administrator or editor views the published content - for example, during a routine content review - the script executes silently in their browser, exfiltrating their session cookie to an attacker-controlled endpoint. … |
| Remediation | Site administrators should update the Ghost Kit plugin to the latest available version via the WordPress plugin repository, verifying the installed version exceeds 3.6.0. … Detailed patch versions, workarounds, and compensating controls in full report. |
