CyberRota Analysis
AI-GeneratedThe vulnerability affects Gotenberg, a Docker-based API for PDF file processing, where concurrent writes to shared data structures can lead to a data race and crash the service. An unauthenticated remote attacker can exploit this flaw to trigger a denial of service by sending a specially crafted multipart request. Organizations using affected versions (8.10.0 to 8.32.0) should prioritize upgrading to version 8.33.0 to mitigate this high-severity risk.

Original NVD Description
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 to the shared ctx.files, ctx.diskToOriginal, and ctx.filesByField maps and slices. Go maps and slices are not safe for concurrent mutation, so a crafted multipart request containing many downloadFrom entries can trigger a data race and terminate the process with a fatal concurrent map writes runtime error. The default configuration enables downloadFrom and disables authentication, allowing an unauthenticated remote attacker to crash an exposed conversion service and cause a denial of service. This issue is fixed in version 8.33.0.
