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
Multiple stored cross-site scripting (XSS) vulnerabilities in TeamPass before 2.1.27.9 allow authenticated remote attackers to inject arbitrary web script or HTML via the (1) URL value of an item or (2) user log history. To exploit the vulnerability, the attacker must be first authenticated to the application. For the first one, the attacker has to simply inject XSS code within the URL field of a shared item. For the second one however, the attacker must prepare a payload within its profile, and then ask an administrator to modify its profile. From there, whenever the administrator accesses the log, it can be XSS'ed.

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 2.1.27.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-15051 is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
