Real-World Exposure
nilsteampassnet/teampassReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
nilsteampassnet/teampass prior to 3.0.9 is vulnerable to code injection. A malicious user could potentially rename a folder with a payload containing malicious code. This could result in an attack on an admin who edits the folder, as the payload could execute upon the admin's interaction with the folder. This attack could potentially allow the attacker to gain unauthorized access to the admin's system or steal sensitive information, or it could force admin to get redirected to a website controlled by the attacker.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nilsteampassnet/teampass, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update nilsteampassnet/teampass to 3.0.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-2859 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
