From 3.0.0 until 3.2.11, mr.Markdown converts attacker-controlled Markdown to HTML without sanitizing raw HTML before assigning it to an ipywidgets.HTML sink. Event-handler attributes and other active HTML can therefore reach the DOM and execute when another user views the application. This issue is fixed in version 3.2.11.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79","CWE-116"],"vendors":[],"products":[],"references":[{"url":"https://github.com/mljar/mercury/commit/c798a85924e6614c6fea7afe5a560e4554a1d09b","tags":[]},{"url":"https://github.com/mljar/mercury/releases/tag/v3.2.11","tags":[]},{"url":"https://github.com/mljar/mercury/security/advisories/GHSA-2658-85cv-9wwq","tags":[]}],"exploitRefs":[{"url":"https://github.com/mljar/mercury/commit/c798a85924e6614c6fea7afe5a560e4554a1d09b","tags":[]},{"url":"https://github.com/mljar/mercury/releases/tag/v3.2.11","tags":[]},{"url":"https://github.com/mljar/mercury/security/advisories/GHSA-2658-85cv-9wwq","tags":[]}],"hasPoc":true,"ai":null}
