Gotenberg is a Docker-powered stateless API for PDF files. In 8.32.0 and earlier, the IsPublicIP function in pkg/gotenberg/outbound.go does not reject the 2002::/16 6to4 prefix, the 64:ff9b::/96 and 64:ff9b:1::/48 NAT64 prefixes, the fec0::/10 deprecated site-local prefix, Teredo, and other...

CVE-2026-42593

Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, pdfengines/merge, pdfengines/split, libreoffice/convert, chromium/convert/url, chromium/convert/html, and chromium/convert/markdown accept stampSource=pdf + stampExpression=/path and watermarkSource=pdf +...

CVE-2026-42594

Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, the webhook middleware spawns a goroutine that holds a reference to the request's echo.Context after the synchronous handler returns ErrAsyncProcess and Echo recycles the context back to its sync.Pool. When a concurrent...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the chromium/convert/url endpoint due to insufficient validation of redirect destinations against the deny-list. An attacker can access internal network resources and sensitive endpoints by supplying ...

CVE-2026-42597 Gotenberg: Chromium URL conversion routes read arbitrary files under /tmp via file:// scheme

Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, the /forms/chromium/convert/url and /forms/chromium/screenshot/url routes accept url=file:///tmp/... from anonymous callers. The default Chromium deny-list intentionally exempts file:///tmp/ so HTML/Markdown routes can lo...

CVE-2026-42592

Gotenberg (v7/v8) contains a DNS rebinding/SSRF issue in the FilterOutboundURL flow. Before 8.32.0, FilterOutboundURL resolves hostnames, filters IPs against a private-address deny-list, but discards the resolved addresses. Chromium then performs its own DNS resolution when navigating to the URL,...
