CVE-2026-49073: Directorist Booking SQL Injection Flaw

CVE-2026-49073 Overview

CVE-2026-49073 is a blind SQL injection vulnerability in the wpWax Directorist Booking plugin for WordPress. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. Affected versions include Directorist Booking from initial release through version 3.0.3. An authenticated attacker with low privileges can inject SQL statements through unsanitized input that the plugin passes to backend database queries. Successful exploitation can disclose database contents and impact data integrity across the WordPress site. The vulnerability is exploitable over the network without user interaction.

Critical Impact
Authenticated attackers can extract sensitive database contents from WordPress sites running Directorist Booking 3.0.3 or earlier via blind SQL injection.

Affected Products

wpWax Directorist Booking plugin for WordPress
All versions from initial release through 3.0.3
WordPress sites with the Directorist Booking plugin installed and active

Technical Details for CVE-2026-49073

Vulnerability Analysis

The vulnerability is a blind SQL injection in the Directorist Booking plugin, classified under [CWE-89]. The plugin accepts attacker-controlled input and incorporates it into SQL statements without proper sanitization or parameterization. Because the injection is blind, attackers infer query results from boolean responses or time-based delays rather than direct output. The attack requires network access and low-level authenticated privileges, but no user interaction. The scope is changed, meaning a successful attack affects resources beyond the vulnerable component itself. Confidentiality impact is high because attackers can read arbitrary database tables, including user records and credentials hashes. Availability impact is low and integrity impact is not directly affected per the CVSS vector.

Root Cause

The root cause is the failure to use prepared statements or sanitize user-supplied input before concatenating it into SQL queries. The plugin processes request parameters and passes them directly to the WordPress $wpdb query interface without applying $wpdb->prepare() placeholders. Refer to the Patchstack Vulnerability Report for additional technical details.

Attack Vector

An authenticated user with at least subscriber-level privileges sends a crafted HTTP request to a vulnerable endpoint in the Directorist Booking plugin. The malicious payload includes SQL syntax that alters the structure of the backend query. The attacker observes timing differences or conditional response variations to extract data one bit at a time. Automated tools such as sqlmap can systematically enumerate database schemas and contents through this channel.

Detection Methods for CVE-2026-49073

Indicators of Compromise

Unusual SQL syntax patterns in web server access logs targeting Directorist Booking endpoints, including UNION SELECT, SLEEP(, BENCHMARK(, or encoded equivalents
Repeated requests from authenticated low-privilege accounts showing incremental boolean variations in parameter values
Spikes in database query latency correlated with requests to plugin endpoints
Outbound data transfers from the WordPress host immediately following suspicious authenticated requests

Detection Strategies

Deploy a web application firewall with SQL injection signatures tuned for WordPress plugin endpoints
Enable MySQL general query logging temporarily on affected hosts and review queries containing unusual operators or sleep functions
Correlate authenticated session activity with abnormal database query patterns using SIEM rules

Monitoring Recommendations

Monitor HTTP requests to Directorist Booking plugin URLs for parameters containing SQL metacharacters such as single quotes, comments, or boolean operators
Alert on authenticated WordPress users generating high request volumes against booking-related endpoints
Track database error logs for syntax errors that may indicate probing activity

How to Mitigate CVE-2026-49073

Immediate Actions Required

Identify all WordPress sites running the Directorist Booking plugin and verify the installed version
Upgrade Directorist Booking to a version later than 3.0.3 once the vendor releases a patched release
Review WordPress user accounts and revoke unnecessary subscriber or contributor-level access
Audit recent database access logs for signs of prior exploitation

Patch Information

At the time of publication, the vendor advisory listed in the Patchstack Vulnerability Report tracks the fix status. Apply the vendor-supplied update immediately upon release and verify the plugin version reports above 3.0.3.

Workarounds

Deactivate and remove the Directorist Booking plugin until a patched version is available
Restrict access to the WordPress site to trusted authenticated users only and disable open user registration
Deploy a web application firewall rule that blocks SQL injection payloads targeting Directorist Booking endpoints
Apply least-privilege principles to the WordPress database user, limiting permissions to only those required by the application

bash

# Configuration example: block SQL injection patterns at the WAF level (ModSecurity)
SecRule ARGS "@rx (?i)(union(.*?)select|sleep\(|benchmark\(|--|/\*)" \
    "id:1009073,phase:2,deny,status:403,msg:'Possible SQLi targeting Directorist Booking (CVE-2026-49073)'"
