CVE-2025-0511

Welcart e-Commerce <= 2.11.9 - Unauthenticated Stored Cross-Site Scripting via name Parameter

Published Feb 12, 2025 CVSS 3.1 · 7.2 High EPSS < 1% KEV · Not listed

Description

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘name’ parameter in all versions up to, and including, 2.11.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Analysis

Technical impact

The plugin contains an unsanitized 'name' input that is stored and later output without proper escaping, allowing any attacker to embed malicious scripts. When an affected page is viewed, the injected code executes in the victim's browser, potentially stealing session cookies, defacing the site, or redirecting the user to malicious domains. This flaw is classified as a stored cross‑site scripting vulnerability (CWE‑79) and can be triggered without any authentication.

Affected Systems

Vulnerable versions of the plugin are all releases of Welcart e‑Commerce for WordPress up to and including 2.11.9. The risk applies to installations that have not upgraded beyond this build.

Risk and Exploitability

The CVSS base score of 7.2 indicates a high severity, but the EPSS score is below 1 %, suggesting that automated exploitation is presently low. The vulnerability is not listed in the CISA KEV catalog. Attackers can exploit the flaw by submitting a crafted 'name' value through any input interface that writes the data to the database, such as product creation or order entry, and then influence a legitimate user to view the affected page.

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 Welcart e‑Commerce to the latest version (2.12.0 or later) where the 'name' field is properly sanitized and escaped.
If upgrading immediately is not possible, restrict the use of the 'name' parameter to authenticated administrators or hard‑code it to safe values; otherwise disable the feature.
Deploy a web application firewall or configure your security plugin to detect and block stored XSS payloads in input data.
