CVE-2026-79569: Movie_Recommend v1.0.0 SQLi Vulnerability

CVE-2026-79569 Overview

CVE-2026-79569 is a SQL injection vulnerability [CWE-89] in Movie_Recommend v1.0.0. The flaw resides in the sort parameter of the /loadingmore endpoint. Attackers can supply crafted SQL statements to extract sensitive information from the backend database without authentication or user interaction.

The vulnerability is remotely exploitable over the network with low attack complexity. Because the affected endpoint accepts untrusted input without sanitization, an attacker can retrieve database records, enumerate schema information, and potentially manipulate stored data.

Critical Impact
Unauthenticated attackers can execute arbitrary SQL queries against the Movie_Recommend database through the sort parameter, exposing confidentiality, integrity, and availability of all stored data.

Affected Products

Movie_Recommend v1.0.0
Deployments exposing the /loadingmore endpoint
Downstream forks retaining the vulnerable sort parameter handler

Technical Details for CVE-2026-79569

Vulnerability Analysis

Movie_Recommend v1.0.0 exposes an HTTP endpoint at /loadingmore that accepts a sort parameter used to construct a database query. The application concatenates user-supplied input directly into the SQL statement without parameterization or input validation. This design allows an attacker to break out of the intended query context and append arbitrary SQL clauses.

Exploitation returns database content in the HTTP response, enabling data exfiltration through techniques such as UNION-based extraction or boolean-based blind injection. The Common Weakness Enumeration classifies this flaw as CWE-89, Improper Neutralization of Special Elements used in an SQL Command.

The published Exploit Prediction Scoring System (EPSS) probability is 0.393%. No public exploit is currently tracked in Exploit-DB, and the vulnerability is not listed on the CISA Known Exploited Vulnerabilities catalog.

Root Cause

The root cause is direct string concatenation of the sort query parameter into an SQL statement executed by the backend. The application does not enforce an allow-list of sortable columns and does not use prepared statements. Any character permitted by the HTTP parser reaches the database engine unmodified.

Attack Vector

An attacker sends an HTTP request to /loadingmore with a crafted sort value containing SQL syntax. Because authentication is not required, exploitation is trivial once the endpoint is reachable. See the GitHub CVE Analysis for a technical walkthrough of the injection payload structure and observed database responses.

Detection Methods for CVE-2026-79569

Indicators of Compromise

HTTP requests to /loadingmore containing SQL keywords such as UNION, SELECT, SLEEP, information_schema, or comment sequences (--, #, /*) in the sort parameter.
Unexpected database errors or long response times correlated with requests to the /loadingmore endpoint.
Outbound data volumes from the Movie_Recommend application server that deviate from historical baselines.

Detection Strategies

Deploy web application firewall (WAF) signatures that flag SQL metacharacters and known injection payloads targeting the sort parameter.
Enable database query logging and alert on queries referencing information_schema, system tables, or unusually long ORDER BY clauses.
Correlate application access logs with database logs to identify single client sessions generating anomalous query patterns.

Monitoring Recommendations

Monitor authentication-less HTTP traffic to /loadingmore for high request rates from a single source.
Track HTTP 500 responses and stack traces returned by the Movie_Recommend application, which often accompany injection probing.
Alert on egress traffic from the database host to unexpected destinations.

How to Mitigate CVE-2026-79569

Immediate Actions Required

Restrict network exposure of the Movie_Recommend /loadingmore endpoint to trusted networks until a patched build is deployed.
Deploy WAF rules that block SQL metacharacters in the sort query parameter.
Review database logs for prior exploitation attempts and rotate any credentials or secrets stored in the affected database.

Patch Information

No vendor patch is referenced in the NVD entry at the time of publication. Operators should track the upstream Movie_Recommend repository for a fixed release and consult the GitHub CVE Analysis for reproduction details.

Workarounds

Refactor the /loadingmore handler to use parameterized queries or prepared statements for all database interactions.
Enforce a server-side allow-list of valid sort values (for example, specific column names) and reject any other input.
Apply least-privilege database credentials so the application account cannot read arbitrary tables or execute administrative statements.

bash

# Example nginx rule to block SQL keywords in the sort parameter
location /loadingmore {
    if ($arg_sort ~* "(union|select|sleep|information_schema|--|#|/\*)") {
        return 403;
    }
    proxy_pass http://movie_recommend_backend;
