CVE-2015-8814 is a high-severity cross-site request forgery (CSRF) vulnerability in Umbraco.CMS (nuget), affecting versions < 7.4.0. It is fixed in 7.4.0.
Umbraco before 7.4.0 allows remote attackers to bypass anti-forgery security measures and conduct cross-site request forgery (CSRF) attacks as demonstrated by editing user account information in the templates.asmx.cs file.
A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones. Typical impact: state-changing actions performed as the victim without their consent.
CVE-2015-8814 has a CVSS score of 8.8 (High). The vector is network-reachable, no 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 (7.4.0). Upgrading removes the vulnerable code path.
nuget
Umbraco.CMS (< 7.4.0)Umbraco.CMS → 7.4.0 (nuget)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 instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether CVE-2015-8814 is reachable in your applications. Explore open-source security for your team.

CVE-2015-8814 has a CVSS score of 8.8 (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.
Umbraco.CMS (nuget) versions < 7.4.0 is affected.
Yes. CVE-2015-8814 is fixed in 7.4.0. Upgrade to this version or later.
Whether CVE-2015-8814 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.

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.
Upgrade Umbraco.CMS to 7.4.0 or later.
