In 8.32.0 and earlier, filename handling in pkg/modules/api/context.go uses filepath.Base on Linux, which does not treat backslashes as path separators, so a multipart filename containing Windows-style parent directory components survives sanitization. The original filename flows through ctx.diskToOriginal and the multi-output PDF routes into archives.FilesFromDisk and archives.Zip.Archive as the generated zip entry name. A remote attacker can submit a name such as ........\\Windows\\System32\\evil.pdf through an upload or an upstream downloadFrom Content-Disposition header, and a Windows archive extractor can write the resulting file outside the intended extraction directory. The affected paths include /forms/pdfengines/split and other multi-output PDF, LibreOffice, and conversion routes, and exploitation can cause arbitrary file writes on a downstream Windows system when a user or process extracts the returned archive. This issue is fixed in version 8.33.0.","state":0,"publishedAt":"2026-08-19T15:17:02.63+00:00","modifiedAt":"2026-10-27T13:10:00.36+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:L","score":8.8,"severity":"HIGH"}],"references":["https://github.com/gotenberg/gotenberg/commit/93d0103585372433e18b351bb16edf4c383932d3","https://github.com/gotenberg/gotenberg/issues/662","https://github.com/gotenberg/gotenberg/releases/tag/v8.33.0","https://github.com/gotenberg/gotenberg/security/advisories/GHSA-hwc4-gmrw-5222"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44829","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-22"],"productCriteria":[],"sourceDates":{"published":"2026-08-19T15:17:02.630","lastModified":"2026-10-27T13:10:00.360"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
