Neuron MySQLWriteTool allows arbitrary/destructive SQL when exposed to untrusted prompts (agent “footgun”)
The advisory, in context
Impact
MySQLWriteTool executes arbitrary SQL provided by the caller using PDO::prepare() + execute() without semantic restrictions.
This is consistent with the name (“write tool”), but in an LLM/agent context it becomes a high-risk capability: prompt injection or indirect prompt manipulation can cause execution of destructive queries such as DROP TABLE, TRUNCATE, DELETE, ALTER, or privilege-related statements (subject to DB permissions).
Who is impacted: Deployments that expose an agent with MySQLWriteTool enabled to untrusted input and/or run the tool with a DB user that has broad privileges.
Patches
Not patched in: 2.8.11
Recommended improvements (even if keeping the tool intentionally powerful):
-
Provide a safer API that supports only constrained operations (e.g.,
insertRecord,updateRecord) with allowlisted tables/columns. -
Add a policy/allowlist layer (e.g., allow only
INSERT/UPDATEon selected tables; forbidDROP/TRUNCATE/ALTER/GRANT). -
Add optional review workflow: log + require human approval for high-risk statements; or “dry-run” mode.
-
Document strongly that the tool must not be exposed to untrusted prompts without additional safeguards.
Workarounds
-
Do not enable
MySQLWriteToolfor public/untrusted agents. -
Use a dedicated DB user with least privilege:
- no
DROP, noALTER, noGRANT, no access to sensitive tables unless necessary
- no
-
Add an application-layer policy rejecting high-risk statements (
DROP,TRUNCATE,ALTER,GRANT,REVOKE,CREATE USER, etc.). -
Implement authorization gating for tool calls (RBAC, allow tool use only for trusted operators).
