Versions prior to 2.23.0 are vulnerable to stored HTML attribute injection in the page metadata fields (`og:title` and `og:description`). An authenticated user with permission to modify page metadata can inject arbitrary HTML attributes into generated `<meta>` tags due to missing output encoding. Under certain browser or DOM interaction scenarios, this may lead to stored cross-site scripting (XSS). Version 2.23.0 fixes the issue."}],"source":{"advisory":"GHSA-wg6r-jwmr-p7gr","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/typemill/typemill/security/advisories/GHSA-wg6r-jwmr-p7gr","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-24T19:38:07.139955Z","id":"CVE-2026-53468","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-24T19:38:32.055Z"}}]}}
