- 7.5 High severity
gotenberg: Server-Side Request Forgery
Gotenberg 8.31.0 before 8.38.0 contains a server-side request forgery vulnerability in IsPublicIP() that allows unauthenticated attackers to bypass private-IP deny-list protections using IPv6 zone identifiers. Attackers can append a zone such as %25eth0 to the
- 7.5 High severity
gotenberg: Concurrent Execution using Shared Resource with Improper Synchronization
Gotenberg is a Docker-powered stateless API for PDF files. From 8.10.0 until 8.33.0, the newContext function in pkg/modules/api/context.go starts one errgroup.Go goroutine for each multipart downloadFrom entry and allows those goroutines to concurrently write
- 7.5 High severity
gotenberg: Incomplete List of Disallowed Inputs
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-
- 8.8 High severity
gotenberg: Improper Limitation of a Pathname to a Restricted Directory
Gotenberg is a Docker-powered stateless API for PDF files. 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

gotenberg: Server-Side Request Forgery
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.34.0, Gotenberg's /forms/libreoffice/convert endpoint allows a specially crafted document to cause LibreOffice to automatically retrieve external HTTP(S) resources and local file resources d
- 9.4 Critical severity
gotenberg: Server-Side Request Forgery
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.31.0, the default deny-lists used by Gotenberg's downloadFrom feature and webhook feature are bypassable. Because the filter is regex-based and case-sensitive, an unauthenticated attacker ca

gotenberg: Server-Side Request Forgery
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, Gotenberg's Chromium URL-to-PDF endpoint (/forms/chromium/convert/url) has no default protection against HTTP/HTTPS-based SSRF. The default deny-list regex only blocks file:// URIs. An
- 7.5 High severity
gotenberg: Concurrent Execution using Shared Resource with Improper Synchronization
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
- 8.2 High severity
gotenberg: Server-Side Request Forgery
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, the LibreOffice conversion endpoint (/forms/libreoffice/convert) passes uploaded documents directly to LibreOffice without inspecting their content. LibreOffice then fetches any embedd

gotenberg: Improper Neutralization of Special Elements used in an OS Command
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.31.0, Gotenberg's /forms/pdfengines/metadata/write HTTP endpoint accepts a JSON metadata object and passes its keys directly to ExifTool via the go-exiftool library. No validation is perform
- 8.2 High severity
gotenberg: External Control of File Name or Path
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.31.0, Gotenberg only checks if the tag is exactly FileName, so System:FileName slips right through and ExifTool happily renames the file. This allows remote attackers to move, rename, and ch
- 9.1 Critical severity
gotenberg: Improper Neutralization of Argument Delimiters in a Command
Gotenberg is a Docker-powered stateless API for PDF files. In versions 8.30.1 and earlier, the metadata write endpoint validates metadata keys for control characters but leaves metadata values unsanitized. A newline character in a metadata value splits the Exi

gotenberg: Server-Side Request Forgery
Gotenberg is an API-based document conversion tool. In versions 8.30.1 and earlier, the default private-IP deny-lists for the --webhook-deny-list and --api-download-from-deny-list flags use a case-sensitive regular expression (^https?://) to match URL schemes.
- 8.7 High severity
gotenberg: Inefficient Regular Expression Complexity
Gotenberg is an API for converting document formats. In 8.29.1 and earlier, Gotenberg uses dlclark/regexp2 to compile user-supplied scope patterns without setting a proper timeout. Users with access to features using this logic can hang workers indefinitely.
