Description
The Vertical scroll image slideshow gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘width’ parameter in all versions up to, and including, 11.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AI Analysis

Impact

The Vertical scroll image slideshow gallery plugin for WordPress allows attackers with Contributor level access or higher to inject arbitrary scripts into the width parameter. The stored cross‑site scripting flaw enables injected code to execute whenever a page using the gallery is requested, potentially allowing the attacker to run scripts in the context of any visitor’s browser.

Affected Systems

The vulnerability affects the gopiplus Vertical scroll image slideshow gallery plugin for WordPress. All releases through version 11.1 are impacted; no other products are listed.

Risk and Exploitability

The CVSS score of 6.4 classifies the weakness as medium severity, and the EPSS score of less than 1% indicates a low probability of exploitation at this time. Because the flaw requires authenticated Contributor level access or higher, an attacker must first obtain valid WordPress credentials. The vulnerability is not listed in the CISA KEV catalog, suggesting it has not been identified as a widely exploited issue yet.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the plugin to a version released after 11.1 that resolves the width parameter sanitization weakness.
  • If an immediate update is not possible, revoke Contributor+ permissions from users who can edit gallery settings or temporarily disable the plugin until a patch is applied.
  • Implement server‑side validation that accepts only numeric values for the width parameter and ensure all output is properly escaped to prevent script execution.
