AI Analysis

Impact

Improper neutralization of user input in the averta Master Slider plugin results in stored cross‑site scripting. A malicious script can be embedded in slider content and executed in the browsers of site visitors who view the affected slider.

Affected Systems

All WordPress sites that use the Master Slider plugin version 3.11.0 or earlier are affected. The flaw exists in the plugin’s content handling routines and is independent of site configuration.

Risk and Exploitability

The CVSS score of 6.5 indicates moderate severity, while the EPSS score of less than 1% reflects a low likelihood of exploitation at this time. The vulnerability is not listed in CISA’s KEV catalog. Exploitation requires the ability to create or modify slider content, after which the stored script is presented to users who view the slider.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the Master Slider plugin to any version newer than 3.11.0, which contains the input‑neutralization fix.
  • Delete any malicious script entries that may already be stored in slider content to remove existing payloads.
  • If the plugin cannot be upgraded immediately, disable the plugin or restrict slider content editing until a patched version is available to prevent further injection.
