The event-handler scan is anchored at `<` and uses `[^>]*?`, which cannot cross the first literal `>`; when a `>` appears inside a quoted attribute value the browser keeps the tag open and parses a subsequent event handler (e.g. onerror), so the detector and browser disagree. A page editor without admin.super privileges can save page content such as `<img src=x title=\">\" onerror=alert(document.domain)>`, which is accepted, stored, and executed in the site origin when any visitor (including unauthenticated users) views the page. Fixed in 2.0.13.","state":0,"publishedAt":"2026-08-14T11:35:38.484+00:00","modifiedAt":"2026-10-08T15:24:33.469+00:00","affected":[{"ecosystem":"Vendor product","name":"grav","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getgrav\",\n                    \"product\": \"grav\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"1.5.2\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"2.0.12\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:composer/getgrav/grav\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":5.1,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/getgrav/grav/security/advisories/GHSA-269c-h76q-8cxw","https://github.com/getgrav/grav/commit/ad9709f865b09b68798fb1ac375b484a8cc1d892","https://www.vulncheck.com/advisories/grav-before-stored-xss-via-quoted-attribute-bypass"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-72832","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-72832","identifiers":["CVE-2026-72832"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
