payloadnpmDescription
Impact
Certain request inputs were not properly validated. An attacker could craft requests that influence SQL query execution, potentially exposing or modifying data in collections.
Patches
This issue has been fixed in v3.79.1 and later. Query input validation has been hardened.
Upgrade to v3.79.1 or later.
Workarounds
Until developers can upgrade:
- Limit access to endpoints that accept dynamic query inputs to trusted users only.
- Validate or sanitize input from untrusted clients before sending it to query endpoints.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for payload, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update payload to 3.79.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-34747 is resolved across your whole dependency graph.
Workarounds
Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
