Description
Frappe Builder versions before 1.36.1 contain a server-side request forgery vulnerability in the convert_to_webp API endpoint, which lacks the has_page_write access control applied to similar asset-ingest handlers and performs an unprotected requests.get call that follows redirects without re-validating resolved IP addresses. A low-privilege authenticated user can supply an image_url pointing to an internal address or use DNS rebinding and open redirects to make the server fetch internal network resources or cloud metadata endpoints, with successful image responses saved to a world-readable /files/ URL enabling data exfiltration or blind probing of internal hosts.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-115717 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Stop reflecting attacker-controlled destinations: resolve every redirect target against an allowlist of paths or hosts you own, prefer a server-side key over a full URL in the request, and reject absolute URLs entirely where the flow only ever needs a relative one.
