CVE-2017-15053 is a medium-severity (CVSS 4.9) Improper Privilege Management vulnerability in nilsteampassnet/teampass. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2017-15053 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

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
TeamPass before 2.1.27.9 does not properly enforce manager access control when requesting roles.queries.php. It is then possible for a manager user to modify any arbitrary roles within the application, or delete any arbitrary role. To exploit the vulnerability, an authenticated attacker must have the manager rights on the application, then tamper with the requests sent directly, for example by changing the "id" parameter when invoking "delete_role" on roles.queries.php.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

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-2017-15053 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-2017-15053 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-2017-15053. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
