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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:L","score":8.8,"severity":null}],"references":["https://github.com/gotenberg/gotenberg/security/advisories/GHSA-hwc4-gmrw-5222","https://github.com/gotenberg/gotenberg/issues/662","https://github.com/gotenberg/gotenberg/commit/93d0103585372433e18b351bb16edf4c383932d3","https://github.com/gotenberg/gotenberg/releases/tag/v8.33.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-62427","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 19, 2026, 2:35:06 PM","dateUpdated":"Aug 19, 2026, 6:19:27 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
