CVE-2026-57714: LatePoint Blind SQL Injection Vulnerability

CVE-2026-57714 Overview

CVE-2026-57714 is a blind SQL injection vulnerability affecting the LatePoint plugin for WordPress. The flaw stems from improper neutralization of special elements in SQL commands [CWE-89]. All versions of LatePoint up to and including 5.6.3 are affected. Attackers can exploit this vulnerability over the network without authentication or user interaction. Successful exploitation lets attackers infer or extract sensitive data from the backend database using time-based or boolean-based inference techniques. The vulnerability carries a scope change, meaning exploitation can impact resources beyond the vulnerable component. LatePoint is a booking and appointment plugin used by WordPress sites, which broadens the potential attack surface across affected installations.

Critical Impact
Unauthenticated remote attackers can perform blind SQL injection against LatePoint versions <= 5.6.3, enabling database content inference and cross-scope impact on WordPress installations.

Affected Products

LatePoint plugin for WordPress, versions n/a through 5.6.3
WordPress sites using LatePoint booking functionality
All deployments exposing LatePoint endpoints to the public internet

Technical Details for CVE-2026-57714

Vulnerability Analysis

The vulnerability is a blind SQL injection flaw in the LatePoint plugin. Blind SQL injection occurs when application responses do not directly return database output, forcing attackers to infer results from response behavior. Attackers typically use boolean-based payloads that change response content or time-based payloads that introduce measurable delays via functions like SLEEP() or BENCHMARK(). Because the vulnerability requires no authentication and no user interaction, automated scanners and mass-exploitation tooling can target vulnerable endpoints at scale. The scope change indicator suggests that exploitation of the plugin can affect data or components outside the LatePoint plugin boundary, likely reaching shared WordPress database tables such as wp_users or wp_options.

Root Cause

The root cause is improper neutralization of user-supplied input passed into SQL queries [CWE-89]. LatePoint fails to consistently apply parameterized queries or escape untrusted input before concatenating it into SQL statements. This allows crafted request parameters to alter query logic and interact with the underlying MySQL database.

Attack Vector

An unauthenticated remote attacker sends crafted HTTP requests to a LatePoint endpoint that reaches the vulnerable query path. The attacker injects SQL fragments into request parameters and observes response differences or timing to extract data byte by byte. Full technical detail is available in the Patchstack SQL Injection Vulnerability advisory.

Detection Methods for CVE-2026-57714

Indicators of Compromise

HTTP requests to LatePoint plugin endpoints containing SQL metacharacters such as ', --, UNION, SLEEP, or BENCHMARK in query parameters or POST bodies
Anomalous MySQL query latency or repeated timing patterns aligned with time-based blind SQLi payloads
Web server access logs showing repeated parameter fuzzing against /wp-admin/admin-ajax.php or LatePoint booking endpoints

Detection Strategies

Deploy web application firewall rules that flag SQL injection payloads targeting LatePoint request parameters
Enable MySQL general query logging or slow query logging to identify inference queries containing conditional sleeps
Correlate WordPress plugin identification with LatePoint version <= 5.6.3 across managed hosts using inventory data

Monitoring Recommendations

Alert on outbound data volume anomalies from database servers hosting WordPress instances
Track failed and successful HTTP responses to LatePoint endpoints for atypical parameter values
Monitor for scanner user-agents and automated tooling probing WordPress plugin paths

How to Mitigate CVE-2026-57714

Immediate Actions Required

Identify all WordPress installations running LatePoint version 5.6.3 or earlier
Update LatePoint to a fixed release once published by the vendor
Restrict access to LatePoint administrative and booking endpoints where feasible using IP allowlists or authentication gateways

Patch Information

A fixed version beyond 5.6.3 should be applied when released by LatePoint. Refer to the Patchstack SQL Injection Vulnerability advisory for the current remediation guidance and patched version details.

Workarounds

Deploy a virtual patch through a web application firewall to block SQL injection payloads targeting LatePoint parameters
Temporarily disable the LatePoint plugin if it is not business critical until a patched version is installed
Enforce least-privilege database credentials for the WordPress database user to limit the impact of successful injection

bash

# Configuration example: WP-CLI commands to identify and disable vulnerable LatePoint installations
wp plugin list --name=latepoint --field=version
wp plugin deactivate latepoint
