Summary
TeamPass Improper Privilege Management
TeamPass before 2.1.27.9 does not properly enforce item access control when requesting items.queries.php. It is then possible to copy any arbitrary item into a directory controlled by the attacker, edit any item within a read-only directory, delete an arbitrary item, delete the file attachments of an arbitrary item, copy the password of an arbitrary item to the copy/paste buffer, access the history of an arbitrary item, and edit attributes of an arbitrary directory. To exploit the vulnerability, an authenticated attacker must tamper with the requests sent directly, for example by changing the "item_id" parameter when invoking "copy_item" on items.queries.php.
Impact
The application assigns, modifies, tracks, or checks privileges incorrectly, allowing a user to gain elevated access. Typical impact: privilege escalation beyond the intended level.
CVE-2017-15055 has a CVSS score of 8.1 (High). The vector is network-reachable, low privileges required, and no user interaction. 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-2017-15055? CVE-2017-15055 is a high-severity improper privilege management vulnerability in nilsteampassnet/teampass (composer), affecting versions < 2.1.27.9. It is fixed in 2.1.27.9. The application assigns, modifies, tracks, or checks privileges incorrectly, allowing a user to gain elevated access.
- How severe is CVE-2017-15055? CVE-2017-15055 has a CVSS score of 8.1 (High). 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-2017-15055? nilsteampassnet/teampass (composer) versions < 2.1.27.9 is affected.
- Is there a fix for CVE-2017-15055? Yes. CVE-2017-15055 is fixed in 2.1.27.9. Upgrade to this version or later.
- Is CVE-2017-15055 exploitable, and should I be worried? Whether CVE-2017-15055 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-2017-15055 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-2017-15055? Upgrade
