Gotenberg < 8.31.0 - Server-Side Request Forgery

Gotenberg before 8.31.0 is vulnerable to server-side request forgery SSRF due to insufficient validation of URLs in the downloadFrom API. An unauthenticated attacker can exploit the flaw by providing specially crafted IPv4-mapped IPv6 addresses such as http://::ffff:127.0.0.1 that bypass the...

CVE-2026-45742

Gotenberg (a Docker-powered stateless PDF conversion API) versions 8.10.0 through 8.32.x contain a race condition in pkg/modules/api/context.go. The newContext function spawns one goroutine per multipart downloadFrom entry, and those goroutines concurrently write to shared maps (ctx.files, ctx.di...

SUSE CVE-2026-42596

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 can supply URLs such as...

Gotenberg has a Race Condition via Multipart `downloadFrom` Handling

Summary Gotenberg is vulnerable to a remote denial of service in multipart downloadFrom handling. A multipart request containing multiple downloadFrom entries causes concurrent goroutines to write to shared maps without synchronization. This can terminate the process with fatal error: concurrent...

Race Condition

Overview Affected versions of this package are vulnerable to Race Condition through the downloadFrom process. An attacker can cause the application to crash and disrupt service availability by sending a crafted multipart request with multiple downloadFrom entries, leading to concurrent writes to...
