DescriptionCVE.org

The Greenshift WordPress plugin before 13.2.0 does not properly escape a block animation attribute before outputting it within an HTML attribute, allowing users with contributor-level access and above to inject arbitrary web scripts that execute when the content is viewed.

AnalysisAI

Stored cross-site scripting in the Greenshift WordPress plugin (all versions before 13.2.0) allows any user with Contributor-level access or higher to inject arbitrary JavaScript via an improperly escaped block animation attribute rendered into an HTML attribute context. When a higher-privileged user such as an administrator views the affected content, the injected script executes in their browser session, enabling session hijacking or unauthorized administrative actions. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold at minimum a Contributor-level WordPress account on the target site - this is a low-privilege role that is commonly granted to guest bloggers or community contributors. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The published CVSS vector (AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H) contains a notable inconsistency: PR:H (High privilege) is assigned, yet the description explicitly states Contributor-level access is sufficient to trigger the vulnerability. … 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 Upgrade the Greenshift WordPress plugin to version 13.2.0 or later - this is the vendor-confirmed patched release per WPScan advisory (https://wpscan.com/vulnerability/f2bd202b-43fc-4ca7-9bab-649ed87e7cbd/). … Detailed patch versions, workarounds, and compensating controls in full report.
