Summary
TeamPass stored cross-site scripting (XSS) vulnerability
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.
Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
CVE-2017-15051 has a CVSS score of 5.4 (Medium). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.1.27.9); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2017-15051? CVE-2017-15051 is a medium-severity cross-site scripting (XSS) vulnerability in nilsteampassnet/teampass (composer), affecting versions < 2.1.27.9. It is fixed in 2.1.27.9. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is CVE-2017-15051? CVE-2017-15051 has a CVSS score of 5.4 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of nilsteampassnet/teampass are affected by CVE-2017-15051? nilsteampassnet/teampass (composer) versions < 2.1.27.9 is affected.
- Is there a fix for CVE-2017-15051? Yes. CVE-2017-15051 is fixed in 2.1.27.9. Upgrade to this version or later.
- Is CVE-2017-15051 exploitable, and should I be worried? Whether CVE-2017-15051 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2017-15051 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2017-15051? Upgrade
