The Admin and Site Enhancements (ASE) WordPress plugin before 9.0.1 does not sanitise uploaded SVG files on every route it accepts them through, allowing users with a role the site owner granted upload access to store a file containing JavaScript which then executes in the browser of anyone who opens it.
AnalysisAI
Stored cross-site scripting in the Admin and Site Enhancements (ASE) WordPress plugin before 9.0.1 allows authenticated users with site-owner-granted upload access to embed malicious JavaScript inside SVG files uploaded through incompletely sanitized routes, which then executes silently in the browser of any user - including administrators - who subsequently opens or previews the file. The plugin fails to apply SVG sanitization uniformly across all upload-accepting endpoints, meaning at least one route bypasses the intended XSS filter. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concurrent conditions: first, the attacker must hold a WordPress user account assigned a role that the site owner has explicitly granted SVG upload access - this is not a default WordPress permission and depends on site-specific role configuration. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 6.8 score (AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H) is partially misleading as a priority signal. … 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 Admin and Site Enhancements (ASE) WordPress plugin to version 9.0.1 or later, which introduces SVG sanitization across all upload routes. … Detailed patch versions, workarounds, and compensating controls in full report. |
