At a glance

CVE-2025-14627 is a medium-severity Server-Side Request Forgery (SSRF) vulnerability in the WP Ultimate CSV Importer WordPress plugin, affecting versions <= 7.35. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 7.36; sites on affected versions should update now. Disclosed January 2026, reported by Dieu Link.

Vulnerability Overview

The WP Import – Ultimate CSV XML Importer for WordPress plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 7.35. This is due to inadequate validation of the resolved URL after following Bitly shortlink redirects in the `upload_function()` method. While the initial URL is validated using `wp_http_validate_url()`, when a Bitly shortlink is detected, the `unshorten_bitly_url()` function follows redirects to the final destination URL without re-validating it. This makes it possible for authenticated attackers with Contributor-level access or higher to make the server perform HTTP requests to arbitrary internal endpoints, including localhost, private IP ranges, and cloud metadata services (e.g., 169.254.169.254), potentially exposing sensitive internal data.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-918: Server-Side Request Forgery (SSRF)

WP Ultimate CSV Importer <= 7.35 carries this weakness at upload_function(), and reaching it takes an account at Contributor level or above. Server-side request forgery means the application fetches a URL supplied by the caller, turning the server into a proxy for requests the attacker could not make directly.

The request originates from inside the hosting network, which is how these flaws reach cloud metadata endpoints, internal admin panels and services that trust local traffic. For WP Ultimate CSV Importer the fix is 7.36: builds <= 7.35 are affected, anything from 7.36 onward is not.

Remediation

Update to version 7.36, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Ultimate CSV Importer 7.36 closes this, and updating the plugin is the step that ends it.
