Description
A server-side request forgery (SSRF) vulnerability in automatisch through commit 41f3c56 allows a low-privileged authenticated user with 'manage Flow' permission to make the server fetch arbitrary URLs and retrieve the full response body via the HTTP Request app's Custom Request action. The packages/backend/src/apps/http-request/actions/custom-request/index.js handler passes the user-supplied URL directly to the HTTP client with no SSRF controls, enabling access to internal services and metadata endpoints.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-72566 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-72566 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-72566. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
