Summary
Cross site scripting in Elefant CMS
A vulnerability, which was classified as problematic, has been found in Elefant CMS 1.3.12-RC. Affected by this issue is some unknown functionality of the component Title Handler. The manipulation with the input leads to basic cross site scripting (Persistent). The attack may be launched remotely. Upgrading to version 1.3.13 is able to address this issue. It is recommended to upgrade the affected component.
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-2017-20059 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 (1.3.13); 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-2017-20059? CVE-2017-20059 is a medium-severity cross-site scripting (XSS) vulnerability in elefant/cms (composer), affecting versions < 1.3.13. It is fixed in 1.3.13. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is CVE-2017-20059? CVE-2017-20059 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 elefant/cms are affected by CVE-2017-20059? elefant/cms (composer) versions < 1.3.13 is affected.
- Is there a fix for CVE-2017-20059? Yes. CVE-2017-20059 is fixed in 1.3.13. Upgrade to this version or later.
- Is CVE-2017-20059 exploitable, and should I be worried? Whether CVE-2017-20059 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-2017-20059 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-2017-20059? Upgrade
elefant/cmsto 1.3.13 or later.
