The White Label CMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.7.12 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
AnalysisAI
Stored Cross-Site Scripting in the White Label CMS WordPress plugin (versions through 2.7.12) permits authenticated administrators to persist arbitrary JavaScript payloads via plugin settings pages, which then execute in the browsers of other users who access affected pages. Exploitation is gated behind two hard constraints: the attacker must hold administrator-level WordPress credentials, and the target site must be either a WordPress multisite installation or a site where the unfiltered_html capability has been explicitly disabled. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold authenticated WordPress administrator-level credentials or higher (PR:H per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.4 (AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N) appropriately reflects the narrow real-world attack surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained WordPress administrator credentials - through credential stuffing, phishing, or a compromised account - navigates to the White Label CMS settings panel and injects a malicious JavaScript payload (e.g., a cookie-stealing script) into a settings field in Admin_Dashboard.php or Settings.php. The payload is stored in the database and silently executes in the browser of any authenticated user who subsequently loads the affected admin page, enabling session token theft or unauthorized actions performed as that victim user. |
| Remediation | An upstream code change addressing this vulnerability is visible in the WordPress plugin repository changeset (https://plugins.trac.wordpress.org/changeset?reponame=&old=3600959%40white-label-cms&new=3600959%40white-label-cms); however, a specific released patched version number is not independently confirmed from the available data - administrators should update to the latest available version of the White Label CMS plugin via the WordPress plugin repository and verify the installed version exceeds 2.7.12. … Detailed patch versions, workarounds, and compensating controls in full report. |
