{"cve":"CVE-2026-42595","nvd":{"published":"2026-05-14T16:16:22.753","modified":"2026-06-17T10:48:07.603","status":"Analyzed","description":"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 unauthenticated attacker can point Chromium at any internal IP — including loopback, RFC 1918 ranges, and cloud metadata endpoints — and receive the response rendered as a PDF. Additionally, even when operators configure a custom deny-list, the protection is bypassed via HTTP redirects. Gotenberg's Chromium instance follows 302 redirects from an attacker-controlled external URL to internal targets without re-validating the redirect destination against the deny-list. This vulnerability is fixed in 8.32.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6},"cwes":["CWE-918"],"references":["https://github.com/gotenberg/gotenberg/security/advisories/GHSA-chwh-f6gm-r836","https://github.com/gotenberg/gotenberg/security/advisories/GHSA-chwh-f6gm-r836"],"products":["thecodingmachine:gotenberg"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-42595","score":0.00313,"percentile":0.24193,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-chwh-f6gm-r836","url":"https://osv.dev/vulnerability/GHSA-chwh-f6gm-r836","summary":"Gotenberg: Server-Side Request Forgery via Chromium URL Endpoint with Redirect-Based Deny-List Bypass","modified":"2026-07-21T13:57:40Z","packages":[{"ecosystem":"Go","name":"github.com/gotenberg/gotenberg/v8","purl":"pkg:golang/github.com/gotenberg/gotenberg/v8","ranges":["<8.32.0"],"fixed":["8.32.0"]}]},{"id":"GO-2026-5324","url":"https://osv.dev/vulnerability/GO-2026-5324","summary":"Gotenberg: Server-Side Request Forgery via Chromium URL Endpoint with Redirect-Based Deny-List Bypass in github.com/gotenberg/gotenberg","modified":"2026-06-25T19:45:30.559623216Z","packages":[{"ecosystem":"Go","name":"github.com/gotenberg/gotenberg/v7","purl":"pkg:golang/github.com/gotenberg/gotenberg/v7","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/gotenberg/gotenberg/v8","purl":"pkg:golang/github.com/gotenberg/gotenberg/v8","ranges":["<8.32.0"],"fixed":["8.32.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
