How the mentioned CVE works:
The vulnerability in LangGraph’s SQLite store implementation stems from its unsafe construction of SQL queries for filter operations. When processing user-supplied filter conditions like `$eq` or $gt, the code directly concatenates these values into the SQL query string instead of using prepared statements with parameter binding. For example, a crafted filter value containing a single quote (‘) terminates the original string and allows an attacker to append their own malicious SQL commands, such as OR '1'='1', to the query. This flaw enables complete control over the database query, bypassing all intended application-level access controls and filters on the checkpoint store.
Platform: LangGraph
Version: 2.0.10
Vulnerability : SQL Injection
Severity: High
date: 2024-10-26
Prediction: Patch 2024-11-02
What Undercode Say:
`sqlite3 checkpoint.db “SELECT FROM checkpoints WHERE value = ‘” + user_input + “‘;”`
`user_input = “x’ OR ‘1’=’1′;–“`
`SELECT FROM checkpoints WHERE value = ‘x’ OR ‘1’=’1′;–‘`
How Exploit:
Craft malicious filter payloads.
Exfiltrate all checkpoint data.
Bypass security filters completely.
Protection from this CVE:
Use parameterized queries.
Upgrade upon patch release.
Sanitize all filter inputs.
Impact:
Unauthorized data access
Sensitive information disclosure
Security filter bypass
