CVE-2025-7662: WordPress Gestion de tarifs SQL Injection

CVE-2025-7662 is an SQL injection vulnerability in the WordPress Gestion de tarifs plugin affecting versions up to 1.4. Authenticated attackers with Contributor access can extract sensitive database information. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2025-7662 Overview

CVE-2025-7662 is a SQL injection vulnerability in the Gestion de tarifs plugin for WordPress. The flaw affects all versions up to and including 1.4. It resides in the tarif and intitule shortcodes, which fail to properly escape user-supplied input and lack sufficient preparation of the underlying SQL query. Authenticated attackers with Contributor-level access or higher can append additional SQL statements to existing queries. Successful exploitation enables extraction of sensitive information from the WordPress database, including user credentials and site configuration data. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact
Authenticated contributors can extract arbitrary data from the WordPress database, including hashed credentials and secret keys stored in wp_users and wp_options.

Affected Products

WordPress Gestion de tarifs plugin versions up to and including 1.4
WordPress installations using the tarif shortcode
WordPress installations using the intitule shortcode

Technical Details for CVE-2025-7662

Vulnerability Analysis

The Gestion de tarifs plugin exposes two shortcodes, tarif and intitule, that accept user-controlled parameters. These parameters are concatenated directly into SQL queries without parameterized statements or proper escaping through $wpdb->prepare(). An attacker with Contributor privileges can embed a shortcode inside a post or page, supplying crafted input that terminates the original query and appends a UNION SELECT or similar statement.

The plugin's query construction logic is visible in the plugin shortcodes source. WordPress contributors can create and preview posts, which triggers shortcode rendering and executes the injected SQL under the database user configured for the WordPress site.

Root Cause

The root cause is improper neutralization of special elements in SQL commands [CWE-89]. The shortcode handlers interpolate attribute values directly into SQL strings. The plugin does not call esc_sql(), nor does it use the placeholder-based wpdb::prepare() method that WordPress provides for safe parameter binding.

Attack Vector

Exploitation requires an authenticated session with Contributor-level privileges or higher. An attacker publishes draft content containing a shortcode such as [tarif id="1 UNION SELECT user_pass FROM wp_users--"]. When the post is previewed or rendered, the WordPress shortcode handler invokes the vulnerable callback, executing the attacker's SQL payload against the WordPress database. The attack is network-based and requires no user interaction beyond standard editorial workflow. Technical details are available in the Wordfence vulnerability analysis.

Detection Methods for CVE-2025-7662

Indicators of Compromise

Unexpected posts or pages containing [tarif] or [intitule] shortcodes with SQL metacharacters such as UNION, SELECT, --, or /* in attribute values.
Database query logs showing SELECT statements against wp_users, wp_usermeta, or wp_options originating from the plugin's shortcode handlers.
Contributor accounts creating or previewing content outside their normal editorial pattern.

Detection Strategies

Audit all draft and published content for shortcode attributes containing SQL keywords or quote characters.
Enable WordPress query logging via the SAVEQUERIES constant and review queries executed by the Gestion de tarifs plugin.
Deploy a web application firewall rule that inspects POST requests to /wp-admin/post.php and /wp-admin/admin-ajax.php for shortcode payloads containing SQL syntax.

Monitoring Recommendations

Monitor WordPress role assignments and alert on new Contributor-or-higher accounts.
Correlate database error log entries with shortcode-rendering requests to identify failed injection attempts.
Track outbound data volume from the web server to detect bulk database extraction.

How to Mitigate CVE-2025-7662

Immediate Actions Required

Deactivate the Gestion de tarifs plugin until a patched version is installed.
Audit all Contributor, Author, Editor, and Administrator accounts and remove unused or suspicious users.
Rotate WordPress secret keys in wp-config.php and reset passwords for all privileged accounts.
Review recent posts and revisions for shortcodes containing SQL injection payloads.

Patch Information

As of the last NVD update on 2026-06-17, all versions up to and including 1.4 of the Gestion de tarifs plugin are affected. Administrators should consult the WordPress plugin page for the latest release and apply any available update that addresses the shortcode input handling.

Workarounds

Restrict the Contributor role from using shortcodes by filtering the_content and stripping [tarif] and [intitule] tags before rendering.
Enforce least-privilege access and revoke publishing rights from untrusted contributors until a patched version is deployed.
Deploy a web application firewall ruleset that blocks SQL metacharacters in shortcode attribute values submitted through the WordPress editor.
