CVE-2025-5082

WP Attachments <= 5.0.12 - Reflected Cross-Site Scripting via attachment_id Parameter

Published May 28, 2025 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed

Description

The WP Attachments plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘attachment_id’ parameter in all versions up to, and including, 5.0.12 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Analysis

Technical impact

The WP Attachments plugin for WordPress is vulnerable in all versions up to 5.0.12 because the attachment_id parameter is not properly sanitized or escaped, which allows unauthenticated attackers to inject JavaScript that is reflected in the page. This reflected cross‑site scripting can execute malicious scripts in a victim's browser when a crafted link containing the vulnerable parameter is opened, potentially allowing an attacker to run arbitrary code within the context of the site.

Affected Systems

The affected product is the WP Attachments plugin from milmor. All releases up to and including version 5.0.12 are impacted. No other vendors are mentioned in the data.

Risk and Exploitability

The CVSS score of 6.1 indicates moderate severity. The EPSS score of less than 1% suggests a very low current exploitation probability. The vulnerability is not listed in the CISA KEV catalog, meaning it has not been widely exploited. Based on the description, the likely attack vector is unauthenticated via a malicious URL that includes an unsanitized attachment_id parameter, which triggers the script when the victim follows the link.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade the WP Attachments plugin to the newest available release, which is expected to contain a fix for the attachment_id XSS issue.
If an upgrade is not possible, review any custom code that accesses the attachment_id parameter and modify it to use WordPress escaping functions such as esc_attr() or esc_html() before rendering.
Implement a web application firewall or input sanitization rule to block or escape JavaScript payloads that might be included in the attachment_id query string before the content is sent to the browser.
