The GenieWords WordPress plugin from 1.5.27 to 1.5.34 does not have authorisation checks on some of its REST API and AJAX actions, and decodes stored values before printing them, allowing unauthenticated users to overwrite its configuration and inject arbitrary web scripts that execute on every front-end page.
AnalysisAI
The GenieWords WordPress plugin versions 1.5.27 through 1.5.34 allows unauthenticated attackers to overwrite plugin configuration via unprotected REST API and AJAX endpoints, then achieves persistent stored XSS on every front-end page because stored values are decoded and printed without sanitization. Any site visitor who loads a front-end page becomes an XSS victim, enabling session hijacking, credential theft, or malicious redirects at scale. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No authentication is required - the affected REST API and AJAX endpoints lack any WordPress capability check or nonce verification, making them reachable by any unauthenticated HTTP client. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.8 with vector AV:N/AC:L/PR:N/UI:R reflects the unauthenticated network-reachable write path (PR:N, AV:N, AC:L) and the requirement that a victim visit a page for XSS to fire (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update the GenieWords plugin to the first version that resolves the authorization bypass and output encoding defects - the exact patched version is not independently confirmed in the available references, so administrators should check the WordPress plugin repository changelog or the WPScan advisory at https://wpscan.com/vulnerability/23dc45bb-e7b6-4cae-81ce-2c6394afb454/ for the confirmed safe release. … Detailed patch versions, workarounds, and compensating controls in full report. |
