Description
Cross-Site Scripting (XSS) was discovered in TeamPass before 2.1.27.9. The vulnerability exists due to insufficient filtration of data (in /sources/folders.queries.php). An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nilsteampassnet/teampass. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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-2017-15278 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.
How O3 protects you
O3 pinpoints whether CVE-2017-15278 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2017-15278. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
