CVE-2026-40315
Published: 14 April 2026
Summary
CVE-2026-40315 is a high-severity SQL Injection (CWE-89) vulnerability in Praison Praisonai. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 21.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SA-8 (Security and Privacy Engineering Principles) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-40315 is an SQL identifier injection vulnerability affecting PraisonAI, a multi-agent teams system, in versions prior to 4.5.133. The issue resides in the SQLiteConversationStore component, where the table_prefix configuration value is directly concatenated into SQL queries using f-strings without validation or sanitization. SQL identifiers cannot be safely parameterized, allowing injected arbitrary SQL fragments to alter query structure. The vulnerability originates from configuration input in config.py, propagates through factory.py, and manifests in SQL query construction in sqlite.py. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-89.
An attacker who can control the table_prefix value, such as through from_yaml or from_dict configuration input, can exploit this vulnerability remotely with low complexity and no privileges required. Successful exploitation enables unauthorized data access, including reading internal SQLite tables like sqlite_master for schema disclosure, as well as manipulation of query results via techniques like UNION-based injection, leading to full query result tampering.
The vulnerability has been addressed in PraisonAI version 4.5.133. Security practitioners should upgrade to this version or later. Relevant details are available in the GitHub security advisory (GHSA-x783-xp3g-mqhp) and the fixing commit (0accebb2e3c3ec2fca66bbea0444fb7a35f0b4ef).
PraisonAI's role as a multi-agent teams system introduces AI/ML relevance, as exploitation could compromise conversation storage and potentially affect agent interactions or data integrity in AI-driven workflows. No real-world exploitation has been reported.

Vulnerability details
PraisonAI is a multi-agent teams system. Prior to 4.5.133, there is an SQL identifier injection vulnerability in SQLiteConversationStore where the table_prefix configuration value is directly concatenated into SQL queries via f-strings without any validation or sanitization. Since SQL identifiers cannot…

be safely parameterized, an attacker who controls the table_prefix value (e.g., through from_yaml or from_dict configuration input) can inject arbitrary SQL fragments that alter query structure. This enables unauthorized data access, such as reading internal SQLite tables like sqlite_master, and manipulation of query results through techniques like UNION-based injection. The vulnerability propagates from configuration input in config.py, through factory.py, to the SQL query construction in sqlite.py. Exploitation requires the ability to influence configuration input, and successful exploitation leads to internal schema disclosure and full query result tampering. This issue has been fixed in version 4.5.133.

Why these techniques?
Remote SQL injection vulnerability in application component directly enables T1190 (Exploit Public-Facing Application) for initial exploitation; facilitates T1005 (Data from Local System) via unauthorized access to SQLite tables and query result manipulation.
