The Simple File List WordPress plugin through 6.3.11 does not properly sanitise and escape a file's description before outputting it on the public file list, allowing unauthenticated users (when front-end file management is enabled) to perform Stored Cross-Site Scripting attacks that execute in the browser of any visitor viewing the list.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Front-end file management must be explicitly enabled in the Simple File List plugin settings - this is a non-default configuration that a site administrator must actively turn on. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS score of 8.8 (High) is structurally inflated by C:H/I:H/A:H ratings that assume full browser-context compromise, but the Scope:Unchanged designation in the original vector underestimates the cross-user impact typical of stored XSS. … 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 Simple File List WordPress plugin to any version released after 6.3.11 - however, a specific confirmed-safe patch version is not identified in the available data (WPScan advisory at https://wpscan.com/vulnerability/fc51a940-8e67-45d0-b47d-b16da288ebb3/ and NVD at https://nvd.nist.gov/vuln/detail/CVE-2026-16617 should be checked for updated patch status). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all WordPress installations running Simple File List versions 6.3.11 or earlier and immediately disable the plugin's front-end file management feature in plugin settings or deactivate the plugin entirely if not operationally critical. …
