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.","state":0,"publishedAt":"2026-10-19T16:11:29.745+00:00","modifiedAt":"2026-10-20T16:11:40.067+00:00","affected":[{"ecosystem":"Vendor product","name":"mercury","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"mljar\",\n                    \"product\": \"mercury\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.0.0, < 3.2.11\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/mljar/mercury/security/advisories/GHSA-2658-85cv-9wwq","https://github.com/mljar/mercury/commit/c798a85924e6614c6fea7afe5a560e4554a1d09b","https://github.com/mljar/mercury/releases/tag/v3.2.11"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-111059","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-111059","identifiers":["CVE-2026-111059"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
