CVE-2026-47760 is a high-severity cross-site scripting (XSS) vulnerability in tinymce (npm), affecting versions >= 6.8.0, < 7.1.0. It is fixed in 7.1.0.
Impact TinyMCE 6.8.x contains an XSS vulnerability caused by improper SVG namespace scope handling in the sanitizer. A crafted payload using nested <svg> elements can bypass attribute sanitization and execute arbitrary JavaScript. Patches This issue affects TinyMCE 6.8.x-7.0.x. The vulnerability is fixed in TinyMCE 7.1.0 and later. Workarounds No official workaround available. Acknowledgements Tiny thanks maple3142 (<https://maple3142.net>) of DEVCORE for their help identifying this vulnerability. References Fix introduced in TinyMCE 7.1.0 though a rewrite of code causing the vulnerability.
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-2026-47760 has a CVSS score of 8.7 (High). 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 (7.1.0). 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-2026-47760 is reachable in your applications. Explore open-source security for your team.

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.
