A double-quote character inside an attacker-controlled style value breaks out of the attribute, allowing arbitrary HTML/attribute injection — and therefore script execution (XSS) — from a crafted `.ods` file wherever the rendered output is inserted as HTML, which is the documented purpose of the function.\n\n### Details\n\nTwo emission sites in `src/ods/to-html/html-renderer.ts` (before 0.14.0, `src/ods-reader/html-renderer.ts`) write document-controlled values into a `style` attribute without escaping:\n\n- **Cell style.** `buildInlineStyle()` assembles a CSS string from the cell's formatting properties (`fo:color`, `fo:font-size`, `fo:font-family`, `fo:background-color`, `fo:text-align`, etc.) with no escaping, and `renderCell` emits it raw as the cell's `style` attribute.\n- **Row height.** `row.height` (from `style:row-height`) is emitted raw into the row element's `style` attribute.\n\nThe same defect in the ODT renderer (`odtToHtml()`) is tracked as GHSA-3cgg-c5pp-57h6 (CVE-2026-113787).\n\n### Impact\n\nAny consumer that renders `odsToHtml()` output as HTML gets XSS from a crafted `.ods` file they convert: untrusted file → arbitrary tags and attributes → script execution in the host page with the page's origin.\n\n### Patches\n\nFixed in 0.14.2. Both sites now route document-controlled values through a shared attribute-escaping helper:\n\n- [`1424227`](https://github.com/GitHubNewbie0/odf-kit/commit/1424227d1ca2716a249b623d1456575ff0331dcc): escape style attribute values in the ODS HTML renderer\n- [`aa64c73`](https://github.com/GitHubNewbie0/odf-kit/commit/aa64c734ebd7e7be40e35fcda83b1144193c3da2): the shared `escapeAttr` helper\n\nUsers should upgrade to 0.14.2 or later.\n\n### Credit\n\nReported by @PethuKannan.","state":0,"publishedAt":"2026-10-23T20:55:31+00:00","modifiedAt":"2026-10-23T21:00:05.2375651+00:00","affected":[{"ecosystem":"npm","name":"odf-kit","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0.9.8"},{"kind":"fixed","version":"0.14.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/GitHubNewbie0/odf-kit/security/advisories/GHSA-2rqm-h6hv-g79v","https://github.com/GitHubNewbie0/odf-kit/commit/1424227d1ca2716a249b623d1456575ff0331dcc","https://github.com/GitHubNewbie0/odf-kit"],"sourceUrl":"https://github.com/advisories/GHSA-2rqm-h6hv-g79v","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-2rqm-h6hv-g79v","identifiers":["GHSA-2rqm-h6hv-g79v"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
