CVE-2025-49263 Overview
CVE-2025-49263 is a blind SQL injection vulnerability in the WC Vendors Marketplace plugin for WordPress, developed by WCVendors. The flaw affects all versions of wc-vendors up to and including 2.5.6. It stems from improper neutralization of special elements used in an SQL command [CWE-89]. An authenticated attacker with high privileges can inject crafted SQL fragments into vulnerable query parameters. Successful exploitation enables data extraction from the WordPress database through inference-based techniques.
Critical Impact
An authenticated attacker can read confidential database contents, including user records and session data, by abusing unsanitized input in the WC Vendors Marketplace plugin. The scope change in the CVSS vector indicates impact beyond the vulnerable component.
Affected Products
- WCVendors WC Vendors Marketplace plugin for WordPress
- All versions from n/a through 2.5.6
- WordPress sites running the wc-vendors plugin alongside WooCommerce

Technical Details for CVE-2025-49263
Vulnerability Analysis
The vulnerability is a blind SQL injection in the WC Vendors Marketplace plugin. The plugin fails to properly sanitize or parameterize user-controlled input before incorporating it into SQL queries executed against the WordPress database. Because the injection is blind, the application does not return query results directly. Attackers infer database contents by observing differences in response timing or boolean response patterns. The flaw requires high-privilege authentication, which limits the attacker pool to accounts such as vendors or administrators within the marketplace plugin's role model. Confidentiality impact is high, while integrity is unaffected and availability impact is low. The scope change indicates that exploitation crosses a security boundary, affecting resources beyond the plugin's own scope.
Root Cause
The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. The plugin concatenates user-supplied input into SQL statements without prepared statements or adequate escaping through wpdb::prepare(). Special characters such as single quotes and SQL operators pass through to the database driver intact.
Attack Vector
The attack vector is network-based with low complexity. An authenticated user with high privileges sends crafted HTTP requests containing SQL payloads to a vulnerable plugin endpoint. The payload alters the query logic, allowing the attacker to enumerate tables, columns, and rows through blind inference. No user interaction is required from a victim.
No public proof-of-concept exploit is referenced in the enriched data. Technical specifics are described in the Patchstack Vulnerability Report.
Detection Methods for CVE-2025-49263
Indicators of Compromise
- HTTP requests to WC Vendors plugin endpoints containing SQL metacharacters such as ', --, UNION, SLEEP(, or BENCHMARK(
- Unusual database query latency on WooCommerce vendor pages or AJAX handlers exposed by wc-vendors
- Authenticated vendor or admin sessions issuing repetitive parameter probing against the same endpoint
- WordPress error logs showing MySQL syntax errors originating from plugin query paths
Detection Strategies
- Inspect web server access logs for parameter values containing SQL syntax submitted to URLs under /wp-admin/admin-ajax.php or vendor dashboard routes
- Enable WordPress query logging and flag queries containing concatenated input from $_GET, $_POST, or $_REQUEST superglobals tied to the plugin
- Deploy a web application firewall (WAF) rule set that identifies blind SQL injection patterns such as time-based payloads
- Correlate authentication events for vendor-role accounts with unusual outbound query volume
Monitoring Recommendations
- Forward WordPress, PHP, and MySQL error logs to a centralized analytics platform for retention and correlation
- Alert on bursts of HTTP 500 responses from plugin endpoints, which often signal SQL injection probing
- Baseline normal vendor account behavior and alert on deviations such as off-hours activity or rapid request rates
- Monitor database user accounts used by WordPress for unexpected SELECT patterns against wp_users and wp_usermeta
How to Mitigate CVE-2025-49263
Immediate Actions Required
- Identify all WordPress installations running the wc-vendors plugin at version 2.5.6 or earlier
- Restrict access to vendor and administrator accounts and review recent privilege assignments
- Place vulnerable sites behind a WAF with SQL injection signatures enabled until patched
- Rotate database credentials and WordPress secret keys if exploitation is suspected
Patch Information
As of the data captured here, the vendor advisory references the Patchstack database entry. Site operators should upgrade wc-vendors to a version later than 2.5.6 once released and confirm the fix through the Patchstack Vulnerability Report. Verify plugin integrity after the update and review the changelog for the SQL injection remediation.
Workarounds
- Temporarily disable the WC Vendors Marketplace plugin if a patched version is not yet available
- Limit the assignment of high-privilege roles such as vendor manager or administrator to trusted users only
- Apply WAF virtual patching rules that block SQL metacharacters in plugin parameters
- Enforce least-privilege on the WordPress database user to restrict access to non-essential tables
# Configuration example: identify vulnerable wc-vendors installations
wp plugin list --name=wc-vendors --fields=name,status,version --allow-root
# Disable the plugin as a temporary mitigation
wp plugin deactivate wc-vendors --allow-root
