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.","state":0,"publishedAt":"2026-08-19T15:17:05.17+00:00","modifiedAt":"2026-10-27T13:10:00.36+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/gotenberg/gotenberg/commit/6671b5e5d30289087ca80130fc76f130cfa4dd7b","https://github.com/gotenberg/gotenberg/releases/tag/v8.33.0","https://github.com/gotenberg/gotenberg/security/advisories/GHSA-vp73-vjw8-8f32"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-45742","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-362"],"productCriteria":[],"sourceDates":{"published":"2026-08-19T15:17:05.170","lastModified":"2026-10-27T13:10:00.360"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
