Contributor Cross Site Scripting (XSS) in TheFox <= 3.9.70 versions.
AnalysisAI
TheFox WordPress theme by tranmautritam in versions 3.9.70 and earlier allows a Contributor-level authenticated attacker to inject persistent Cross-Site Scripting payloads into theme-specific input fields, which then execute in the browsers of any user who views the affected content. The Changed Scope (S:C) in the CVSS vector confirms the payload crosses security boundaries into the victim browser context, enabling session token theft, credential harvesting, or unauthorized administrative actions against higher-privileged users such as editors or site admins. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid WordPress Contributor-level account (or higher) on the target installation - confirmed by CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (Medium) appropriately reflects the meaningful authentication barrier imposed by PR:L (Contributor account required) and the necessary victim interaction (UI:R), which together prevent opportunistic unauthenticated mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a Contributor-level WordPress account on a target site running TheFox 3.9.70 or earlier, then embeds a malicious JavaScript payload in a theme-specific field such as a custom shortcode attribute, theme widget, or post meta field. When a site administrator or editor navigates to the affected page to review or publish content, the injected script silently executes in their browser, exfiltrating their session cookie to an attacker-controlled server and enabling full account takeover without any further authentication. … |
| Remediation | Update the TheFox theme to a version released after 3.9.70 once a patched release is published by tranmautritam; check the Envato/ThemeForest marketplace or the Patchstack advisory at https://patchstack.com/database/wordpress/theme/thefox/vulnerability/wordpress-thefox-theme-3-9-70-cross-site-scripting-xss-vulnerability for patch availability, as no specific fixed version is confirmed in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
