{"id":"CVE-2026-53468","summary":"Typemill has Stored HTML Attribute Injection in Metadata Fields","details":"Typemill is a flat-file, Markdown-based content management system designed for informational documentation websites. 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 `\u003cmeta\u003e` 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.","aliases":["GHSA-wg6r-jwmr-p7gr"],"modified":"2026-08-23T03:53:38.941910150Z","published":"2026-08-21T21:16:07.987Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53468.json"},"references":[{"type":"WEB","url":"https://github.com/typemill/typemill/releases/tag/v2.23.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53468.json"},{"type":"ADVISORY","url":"https://github.com/typemill/typemill/security/advisories/GHSA-wg6r-jwmr-p7gr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53468"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/typemill/typemill","events":[{"introduced":"0"},{"fixed":"31b72eacb43cd684edd396c53664b0ecabdf2cf5"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.23.0"}]}}],"versions":["v2.22.0","v2.21.3","v2.21.2","v2.21.1","v2.21.0","v2.20.2","v2.20.1","v2.20.0","v2.19.4","v2.19.3","v2.19.2","v2.19.1","v2.19.0","v2.18.4","v2.18.3","v2.18.2","v2.18.1","v2.18.0","v2.17.4","v2.17.1","v2.17.3","v2.17.2","v2.17.0","latest","2.16.2","2.16.1","2.16.0","2.15.0","2.6.0","1.1.6","1.1.5","1.1.4","1.1.3","1.1.2","1.1.1.0","1.1.1","1.1.01","1.1.0","1.0.3","1.0.2","1.0.1","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53468.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N"}]}
