Vanna through 2.0.2 contains a path traversal vulnerability in the FileSystemConversationStore persistence integration that allows unauthenticated remote attackers to write attacker-controlled JSON files to arbitrary filesystem locations and read conversation metadata from outside the intended store base directory. Attackers can supply path traversal sequences in the conversation_id parameter submitted to the unauthenticated chat API endpoints to escape the base directory during both write and read operations, enabling arbitrary file write with attacker-controlled content and unauthorized file read on the server filesystem.
A security vulnerability has been detected in vanna-ai vanna up to 2.0.2. The affected element is an unknown function of the component Legacy Flask API. The manipulation leads to improper authorization. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-5321 is a medium severity vulnerability in vanna-ai vanna versions up to 2.0.2 involving a permissive cross-domain policy that allows untrusted domains. This flaw exists in an unspecified functionality of the FastAPI/Flask server component and can be exploited remotely without user interaction or privileges. The vulnerability could enable unauthorized cross-domain interactions due to improper policy restrictions. The vendor has not responded to the disclosure, and no official patch or mitigation guidance is currently available. Exploit code has been published, but no known widespread exploitation has been reported.
CVE-2026-5320 is a medium-severity vulnerability in vanna-ai vanna versions up to 2.0.2 affecting the Chat API Endpoint at /api/vanna/v2/. The issue involves missing authentication, allowing remote attackers to manipulate the endpoint without proper verification. The exploit is publicly available, but no vendor response or patch has been provided. The vulnerability has a CVSS 4.0 base score of 6.9, indicating moderate risk. No known exploits in the wild have been reported yet.
A vulnerability was detected in vanna-ai vanna up to 2.0.2. Affected by this vulnerability is the function ask of the file vanna\legacy\base\base.py. Performing a manipulation results in sql injection. The attack is possible to be carried out remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A security vulnerability has been detected in vanna-ai vanna up to 2.0.2. Affected is the function exec of the file /src/vanna/legacy. Such manipulation leads to injection. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability was found in vanna-ai vanna up to 2.0.2. Affected by this vulnerability is the function update_sql/run_sql of the file src/vanna/legacy/flask/__init__.py of the component Endpoint. Performing a manipulation results in server-side request forgery. The attack may be initiated remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability has been found in vanna-ai vanna up to 2.0.2. Affected is the function update_sql of the file src/vanna/legacy/flask/__init__.py of the component Endpoint. Such manipulation leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A flaw has been found in vanna-ai vanna up to 2.0.2. This impacts the function remove_training_data of the file src/vanna/legacy/google/bigquery_vector.py. This manipulation of the argument ID causes sql injection. The attack can be initiated remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Vanna v0.6.3 is vulnerable to SQL injection via Snowflake database in its file staging operations using the `PUT` and `COPY` commands. This vulnerability allows unauthenticated remote users to read arbitrary local files on the victim server, such as `/etc/passwd`, by exploiting the exposed SQL queries through a Python Flask API.
vanna-ai/vanna version v0.3.4 is vulnerable to SQL injection in some file-critical functions such as `pg_read_file()`. This vulnerability allows unauthenticated remote users to read arbitrary local files on the victim server, including sensitive files like `/etc/passwd`, by exploiting the exposed SQL queries via a Python Flask API.
Vanna v0.3.4 is vulnerable to SQL injection in its DuckDB integration exposed to its Flask Web APIs. Attackers can inject malicious SQL training data and generate corresponding queries to write arbitrary files on the victim's file system, such as backdoor.php with contents `<?php system($_GET[0]); ?>`. This can lead to command execution or the creation of backdoors.
In the latest version of vanna-ai/vanna, the `vanna.ask` function is vulnerable to remote code execution due to prompt injection. The root cause is the lack of a sandbox when executing LLM-generated code, allowing an attacker to manipulate the code executed by the `exec` function in `src/vanna/base/base.py`. This vulnerability can be exploited by an attacker to achieve remote code execution on the app backend server, potentially gaining full control of the server.
