CVE-2026-9364 Overview
CVE-2026-9364 is a SQL injection vulnerability in projectworlds Online Art Gallery Shop 1.0. The flaw resides in the /admin/adminHome.php script, where the social_linked parameter is concatenated into a database query without proper sanitization. Remote attackers can manipulate the parameter to inject arbitrary SQL statements against the backend database. The exploit has been publicly disclosed, increasing the risk of opportunistic abuse against exposed installations. The vulnerability is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Authenticated or unauthenticated attackers may read, modify, or delete database records by manipulating the social_linked parameter via remote HTTP requests.
Affected Products
- projectworlds Online Art Gallery Shop 1.0

Technical Details for CVE-2026-9364
Vulnerability Analysis
The vulnerability exists in the administrative interface of Online Art Gallery Shop 1.0. The /admin/adminHome.php endpoint processes the social_linked argument and passes it directly into a SQL query. Because the input is not validated, sanitized, or parameterized, an attacker can break out of the intended query context. This allows the attacker to append additional SQL clauses such as UNION SELECT, conditional payloads, or stacked statements depending on the database driver. The attack is remote and does not require complex preconditions.
Root Cause
The root cause is improper neutralization of special elements in a downstream SQL component [CWE-74]. The application concatenates user-supplied data into a query string rather than using prepared statements with bound parameters. As a result, any quote characters, comment sequences, or SQL keywords sent in the social_linked parameter are interpreted as code by the database engine.
Attack Vector
An attacker sends a crafted HTTP request to /admin/adminHome.php with a malicious value in the social_linked parameter. Because the vulnerability is reachable over the network with low attack complexity, exploitation can be automated using standard SQL injection tooling. Successful exploitation can disclose administrator credentials, exfiltrate customer data, or pivot to further compromise of the hosting environment. Public proof-of-concept material is referenced in the GitHub CVE Issue Tracker and VulDB entry #365327.

Detection Methods for CVE-2026-9364
Indicators of Compromise
- HTTP requests to /admin/adminHome.php containing SQL metacharacters such as ', --, UNION, or SLEEP( in the social_linked parameter.
- Unexpected administrative configuration changes or new rows in the gallery's settings tables.
- Web server access logs showing repeated probing of the admin endpoint from a single source IP.
Detection Strategies
- Inspect web server and PHP application logs for anomalous query strings or POST bodies targeting social_linked.
- Deploy a web application firewall (WAF) rule that flags SQL injection signatures on requests to administrative PHP files.
- Correlate database error messages with inbound HTTP traffic to identify injection attempts that triggered query failures.
Monitoring Recommendations
- Forward web server, PHP error, and database logs to a centralized analytics platform for cross-source correlation.
- Alert on outbound database connections originating from the web tier outside normal application patterns.
- Track baseline query volume per endpoint and trigger alerts when /admin/adminHome.php traffic deviates significantly.
How to Mitigate CVE-2026-9364
Immediate Actions Required
- Restrict network access to /admin/ paths using IP allowlists or VPN-only access until a patched build is available.
- Audit the application database for unauthorized accounts, modified records, or exfiltration evidence.
- Rotate administrator credentials and database user passwords if the system was exposed to the internet.
Patch Information
No vendor patch has been published in the referenced advisories at the time of disclosure. Track the VulDB advisory #365327 and the GitHub CVE Issue Tracker for vendor updates. Until a fix is released, treat all Online Art Gallery Shop 1.0 deployments as vulnerable.
Workarounds
- Modify /admin/adminHome.php to use parameterized queries or PDO prepared statements for the social_linked input.
- Apply server-side input validation that rejects non-alphanumeric characters where they are not required.
- Place the application behind a WAF with SQL injection signature enforcement on administrative endpoints.
