CVE-2024-10761 is a medium-severity cross-site scripting (XSS) vulnerability in Umbraco.Cms (nuget), affecting versions >= 10.8.7, < 10.8.8. It is fixed in 10.8.8, 13.5.3, 14.3.2, 15.1.2.
Impact Authenticated users are able to exploit an XSS vulnerability when viewing previewed content. Patches Will be patched in 10.8.8, 13.5.3, 14.3.2 and 15.1.2. Workarounds None available.
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-2024-10761 has a CVSS score of 4.3 (Medium). 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 (10.8.8, 13.5.3, 14.3.2, 15.1.2). Upgrading removes the vulnerable code path.

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-2024-10761 is reachable in your applications. Explore open-source security for your team.

Whether CVE-2024-10761 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.

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.
