CVE-2026-49771 Overview
CVE-2026-49771 is a blind SQL injection vulnerability in the Photo Gallery by 10Web WordPress plugin. The flaw stems from improper neutralization of special elements used in SQL commands [CWE-89]. It affects all versions of Photo Gallery by 10Web up to and including 1.8.41.
An authenticated attacker with high privileges can inject malicious SQL statements through vulnerable plugin parameters. The scope is changed, meaning the impact reaches resources beyond the vulnerable component. Successful exploitation can expose sensitive WordPress database contents and degrade site availability.
Critical Impact
Authenticated attackers can extract confidential data from the WordPress database through blind SQL injection, with scope change affecting resources beyond the plugin itself.
Affected Products
- Photo Gallery by 10Web WordPress plugin versions through 1.8.41
- WordPress sites with the vulnerable plugin installed and activated
- Multi-tenant WordPress installations sharing the affected database

Technical Details for CVE-2026-49771
Vulnerability Analysis
The vulnerability resides in the Photo Gallery by 10Web plugin's handling of user-controlled input passed into SQL queries. The plugin fails to properly sanitize or parameterize input before concatenating it into database statements. This permits an attacker to alter the structure of the resulting SQL query.
Because the vulnerability is blind, the application does not return query results directly to the attacker. Instead, attackers infer data by observing differences in response behavior or timing. Boolean-based and time-based techniques are typical exploitation methods for blind SQL injection flaws.
The attack requires high-privilege authentication, limiting exploitation to users such as administrators or roles with plugin management access. However, the scope change indicates that successful injection can affect resources outside the plugin's security boundary, including the broader WordPress database and any co-resident application data.
Root Cause
The root cause is the absence of prepared statements or proper input escaping in the plugin's database access layer. User-supplied parameters reach SQL queries without validation against expected types or whitelisted values. WordPress provides $wpdb->prepare() for parameterized queries, but the vulnerable code paths do not consistently use this mechanism.
Attack Vector
The attack vector is network-based and requires authenticated access to the WordPress admin interface. An attacker with elevated privileges submits crafted parameters to plugin endpoints that build SQL queries from user input. The blind nature means attackers iteratively extract data character-by-character through inference rather than direct output.
The vulnerability mechanism is documented in the Patchstack SQL Injection Vulnerability advisory. No public proof-of-concept code is available at this time.
Detection Methods for CVE-2026-49771
Indicators of Compromise
- Unusual SQL syntax patterns in WordPress access logs targeting Photo Gallery plugin endpoints
- Repeated requests with SLEEP(), BENCHMARK(), or conditional IF() SQL keywords in query parameters
- Anomalous response time patterns from /wp-admin/ requests interacting with the Photo Gallery plugin
- Authenticated admin sessions issuing high volumes of parameterized requests to gallery management endpoints
Detection Strategies
- Deploy a web application firewall rule set tuned for SQL injection patterns against WordPress admin paths
- Enable WordPress database query logging and review queries originating from the Photo Gallery plugin for unexpected syntax
- Monitor authenticated admin activity for behavioral anomalies including session geographic mismatches and unusual request cadence
- Correlate WAF alerts with WordPress audit logs to identify privileged account abuse
Monitoring Recommendations
- Forward WordPress access logs and PHP error logs to a centralized SIEM for retention and analysis
- Alert on database errors referencing SQL syntax failures associated with the Photo Gallery plugin
- Track administrator account creation, role changes, and login source anomalies
- Establish baselines for normal Photo Gallery admin activity and alert on deviations
How to Mitigate CVE-2026-49771
Immediate Actions Required
- Update Photo Gallery by 10Web to the latest patched version released after 1.8.41
- Audit administrator and editor accounts and remove unused or stale privileged users
- Enforce strong authentication and multi-factor authentication for all WordPress admin accounts
- Review recent database activity for signs of unauthorized data access or modification
Patch Information
The vendor has released a patched version of the Photo Gallery by 10Web plugin addressing this issue. Refer to the Patchstack advisory for the fixed version and update instructions. Apply the update through the WordPress plugin manager or by replacing plugin files manually.
Workarounds
- Temporarily deactivate the Photo Gallery by 10Web plugin if immediate patching is not feasible
- Restrict access to /wp-admin/ paths by IP allowlist at the web server or reverse proxy layer
- Deploy a WAF rule set blocking SQL injection signatures on plugin endpoints until patching completes
- Apply principle of least privilege and reduce the number of accounts holding administrator capabilities
# Configuration example: WordPress CLI plugin update
wp plugin update photo-gallery --version=latest
wp plugin list --name=photo-gallery --fields=name,status,version
