mongoshnpmDescription
The MongoDB Shell may be susceptible to control character injection where an attacker with control of the user’s clipboard could manipulate them to paste text into mongosh that evaluates arbitrary code. Control characters in the pasted text can be used to obfuscate malicious code. This issue affects mongosh versions prior to 2.3.9.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mongosh, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update mongosh to 2.3.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-973h-3x6p-qg37 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
