CVE-2026-45806
HIGHPenpot: Authenticated SSRF in remote image import via create-file-media-object-from-url
Description
Penpot is an open-source design tool for design and code collaboration. Prior to 2.15.0, Penpot's remote image import passed the user-controlled url from frontend/src/app/main/data/workspace/media.cljs into the backend RPC method :create-file-media-object-from-url in backend/src/app/rpc/commands/media.clj, where media/download-image in backend/src/app/media.clj used the shared HTTP client without destination filtering, allowing an authenticated file editor to reach internal-only endpoints. This issue is fixed in version 2.15.0.
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-2026-45806 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-2026-45806 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-2026-45806. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-45806 in your dependencies?
O3 detects CVE-2026-45806 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
