Description
A Server-Side Request Forgery (SSRF) vulnerability in Google Cloud Gemini Enterprise Agent Platform App Builder versions prior to 2026-06-01 on Google Cloud Platform allows an unauthenticated attacker to leak the Compute Engine default service account access token.
This vulnerability was patched on 01 June 2026. Users will need to redeploy their previously deployed apps.
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-2026-19486 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-2026-19486 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-2026-19486. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
