CVE-2026-45213: BEAR woo-bulk-editor SQLi Vulnerability

CVE-2026-45213 Overview

CVE-2026-45213 is a blind SQL injection vulnerability in the RealMag777 BEAR (woo-bulk-editor) WordPress plugin. The flaw affects all versions up to and including 1.1.7.1. The issue is classified under CWE-89, Improper Neutralization of Special Elements used in an SQL Command. Authenticated attackers with high privileges can inject malicious SQL fragments into queries processed by the plugin. Successful exploitation allows attackers to read sensitive database contents, including WordPress user credentials, session tokens, and customer order data stored by WooCommerce.

Critical Impact
An authenticated attacker can extract arbitrary data from the WordPress database through blind SQL injection in the BEAR woo-bulk-editor plugin.

Affected Products

RealMag777 BEAR (woo-bulk-editor) plugin versions n/a through 1.1.7.1
WordPress sites running the affected plugin with WooCommerce
Any environment where the plugin is installed and reachable over the network

Technical Details for CVE-2026-45213

Vulnerability Analysis

The BEAR woo-bulk-editor plugin extends WooCommerce with bulk product editing functionality. The plugin processes user-supplied parameters and incorporates them into SQL statements without proper parameterization or escaping. An authenticated user with administrative-level access to bulk editor endpoints can manipulate query structure by injecting SQL syntax through request parameters.

The injection is blind, meaning the application does not return query results directly in the HTTP response. Attackers infer database contents through boolean-based or time-based techniques. Boolean-based exploitation observes differences in application behavior across crafted true and false conditions. Time-based exploitation uses functions such as SLEEP() to confirm conditional execution.

The vulnerability scope is changed, indicating that a successful attack affects resources beyond the vulnerable plugin component. Confidentiality impact is high because the WordPress database contains password hashes, API keys, and customer records. Integrity is unaffected by the injection itself, while availability impact is limited.

Root Cause

The root cause is the use of unsanitized input directly in SQL queries within plugin handlers. The plugin fails to apply $wpdb->prepare() with placeholder substitution or to validate parameter types before query construction. This pattern violates WordPress secure coding guidance for database access.

Attack Vector

Exploitation requires network access to the WordPress admin interface and authenticated high-privilege credentials. The attacker submits crafted requests to vulnerable bulk editor endpoints. Parameters that should contain identifiers or filter values instead carry SQL payloads such as 1 AND (SELECT 1 FROM (SELECT SLEEP(5))a). The server executes the modified query, and the attacker measures response timing or behavioral differences to extract data character by character.

No verified proof-of-concept code is publicly available. See the Patchstack advisory for additional technical context.

Detection Methods for CVE-2026-45213

Indicators of Compromise

HTTP requests to BEAR plugin endpoints under /wp-admin/admin-ajax.php or /wp-admin/admin.php?page=bear containing SQL keywords such as UNION, SELECT, SLEEP, or BENCHMARK
Anomalously long response times for admin-ajax requests originating from authenticated sessions
Unexpected wpdb errors written to debug.log referencing the woo-bulk-editor plugin
Authenticated administrator sessions executing high volumes of bulk edit requests within short time windows

Detection Strategies

Inspect web server access logs for query strings containing URL-encoded SQL metacharacters targeting plugin endpoints
Enable WordPress query logging and alert on SELECT statements with conditional time delays
Deploy a web application firewall ruleset matching SQL injection patterns specifically on woo-bulk-editor request paths
Correlate administrator authentication events with subsequent bulk editor activity to identify credential abuse

Monitoring Recommendations

Forward WordPress, PHP-FPM, and web server logs to a centralized SIEM for retention and correlation
Monitor MySQL slow query logs for queries originating from the plugin that exceed normal baseline duration
Track failed and successful administrator logins to detect credential compromise that precedes exploitation
Alert on plugin file modifications outside of scheduled update windows

How to Mitigate CVE-2026-45213

Immediate Actions Required

Identify all WordPress installations running the BEAR (woo-bulk-editor) plugin and inventory installed versions
Deactivate the plugin on any site running version 1.1.7.1 or earlier until a patched release is installed
Rotate WordPress administrator passwords and any API keys stored in the database if exploitation is suspected
Review wp_users, wp_options, and WooCommerce order tables for unauthorized reads or modifications

Patch Information

At the time of NVD publication, no fixed version is referenced in the advisory. Monitor the Patchstack advisory and the plugin vendor channels for a release that supersedes 1.1.7.1. Apply the patched version through the WordPress plugin updater once available.

Workarounds

Restrict access to /wp-admin using IP allowlisting at the web server or reverse proxy layer
Enforce multi-factor authentication for all WordPress administrator accounts to reduce credential abuse
Apply web application firewall virtual patching rules that block SQL injection payloads on bulk editor endpoints
Remove the plugin entirely if bulk editing functionality is not required for business operations

bash

# Example WAF rule fragment to block SQL keywords on the plugin endpoint
# ModSecurity rule (adapt to your environment)
SecRule REQUEST_URI "@contains woo-bulk-editor" \
  "chain,phase:2,deny,status:403,id:1026045213,msg:'Block SQLi on BEAR plugin'"
  SecRule ARGS "@rx (?i)(union(\s+all)?\s+select|sleep\s*\(|benchmark\s*\()" \
