WordPress Gallery Plugin SQL Injection via Post Meta

The Gallery by BestWebSoft plugin for WordPress is vulnerable to SQL Injection via the '_gallery_order_{post_id}' parameter array keys in all versions up to, and including, 4.7.9. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The `gllr_save_postdata()` function stores unsanitized array keys from `$_POST` directly into post meta, which are later used in SQL queries without prepared statements. This makes it possible for authenticated attackers, with Editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Casky was already ahead

This CVE exploits attack patterns that Casky's 322matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

The Gallery by BestWebSoft plugin for WordPress contains a critical SQL injection vulnerability (CWE-89) affecting all versions up to 4.7.9. The vulnerability exists in the `gllr_save_postdata()` function, which fails to properly escape user-supplied array keys from `$_POST` parameters before storing them as post metadata. These unsanitized keys are later used directly in SQL queries without prepared statements, allowing attackers to inject arbitrary SQL code through the `_gallery_order_{post_id}` parameter. With a CVSS score of 7.2, this vulnerability impacts WordPress sites running the Gallery plugin, potentially compromising data confidentiality, integrity, and availability. The threat is particularly serious because WordPress plugins are frequently targeted, and SQL injection remains a high-impact attack vector for database manipulation and unauthorized data access.

Casky's 322 mapped security skills leverage Claude's extended reasoning to detect the attack patterns associated with this vulnerability across MITRE ATT&CK techniques TA0001 (Initial Access) and TA0043 (Reconnaissance). Practitioners using Casky would identify detection patterns including: malicious POST requests containing SQL metacharacters (parentheses, quotes, UNION statements) in the `_gallery_order_{post_id}` array keys; suspicious database query logs showing unexpected SQL syntax originating from WordPress meta operations; and unauthorized access to sensitive database tables through injected SELECT, INSERT, or UPDATE statements. The platform's skill correlation would reveal how reconnaissance activities (TA0043) precede exploitation attempts, with attackers first probing plugin versions before crafting version-specific payloads. Security teams would see findings correlated to query parameter tampering, unusual database activity patterns, and potential data exfiltration indicators—all mapped to defensive security controls that address insufficient input validation and lack of parameterized query usage.
