CVE-2026-69704 Overview
CVE-2026-69704 is a SQL injection vulnerability in the Atals-Livre application. The flaw resides in the supp() deletion helper function, which passes unsanitized input from a GET parameter directly into a database query. Attackers with the required privileges can inject arbitrary SQL syntax through the vulnerable parameter. Successful exploitation permits unauthorized database operations, including record deletion and data extraction. The weakness is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.
Critical Impact
Attackers can manipulate backend SQL queries to delete records or extract sensitive data from the Atals-Livre database via a network-accessible GET parameter.
Affected Products
- Atals-Livre (open-source project hosted on GitHub by maintainer maximeAmini)
- All versions containing the vulnerable supp() deletion helper function
- Deployments exposing the affected endpoint over the network

Technical Details for CVE-2026-69704
Vulnerability Analysis
Atals-Livre implements a deletion helper named supp() that constructs a SQL statement using input taken directly from a GET parameter. The application does not sanitize, validate, or parameterize the value before concatenating it into the query. This allows an attacker to break out of the intended query context and append arbitrary SQL clauses. Because the vulnerable helper handles record deletion, exploitation can result in destructive database changes as well as data disclosure via injection techniques such as UNION-based extraction. Exploitation requires the attacker to reach the deletion endpoint with the necessary privilege level, but no user interaction is needed.
Root Cause
The root cause is missing input neutralization in the supp() function. User-controlled data from a GET request flows into a dynamic SQL string without prepared statements or type coercion. This is a textbook [CWE-89] pattern in which trust boundaries between the HTTP request layer and the data access layer are not enforced.
Attack Vector
An authenticated attacker sends a crafted HTTP GET request to the endpoint that invokes supp(). Malicious SQL payloads embedded in the vulnerable parameter alter the resulting query. The attacker can drop or delete rows, chain additional statements where the driver permits, or use boolean and UNION techniques to exfiltrate data. Refer to the VulnCheck Advisory for SQL Injection and the GitHub Gist PoC for exploitation details.
Detection Methods for CVE-2026-69704
Indicators of Compromise
- HTTP GET requests to the Atals-Livre deletion endpoint containing SQL metacharacters such as ', --, ;, UNION, or SELECT in query parameters
- Unexpected DELETE, DROP, or UNION SELECT statements in database query logs originating from the web application user
- Sudden loss of rows in Atals-Livre tables without corresponding legitimate admin activity
- Web server access logs showing URL-encoded SQL payloads (%27, %20OR%201=1) targeting the supp handler
Detection Strategies
- Enable database query logging and alert on statements that contain tautologies or UNION clauses issued by the application service account
- Deploy a web application firewall (WAF) rule set that inspects GET parameters for SQL injection signatures on Atals-Livre endpoints
- Correlate web access logs with database audit logs to identify anomalous request-to-query patterns
Monitoring Recommendations
- Baseline normal GET parameter values for the Atals-Livre deletion endpoint and alert on outliers
- Monitor for spikes in HTTP 500 errors from the application, which often accompany failed SQL injection probes
- Track privileged user sessions that trigger deletion operations and validate them against change-management records
How to Mitigate CVE-2026-69704
Immediate Actions Required
- Restrict access to the Atals-Livre deletion endpoint to trusted administrative networks until a fix is deployed
- Review database audit logs for unauthorized DELETE or data-extraction queries since the application was first exposed
- Rotate database credentials used by Atals-Livre if compromise is suspected
- Apply a WAF rule that blocks SQL metacharacters in GET parameters handled by the supp() function
Patch Information
No official vendor patch is referenced in the NVD entry at publication time. Maintainers and users should monitor the GitHub Project Repository for remediation commits and the VulnCheck Advisory for SQL Injection for updated guidance. Code owners should refactor supp() to use parameterized queries or prepared statements and enforce strict type validation on the GET parameter.
Workarounds
- Disable or gate the vulnerable deletion route behind additional server-side authorization checks
- Implement an input allow-list that accepts only numeric identifiers where the supp() function expects a record ID
- Place the application behind a reverse proxy configured to reject requests containing SQL metacharacters in the affected parameter
- Run the Atals-Livre database account with least-privilege permissions to limit blast radius from injection
