EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2026-32879 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
A logic flaw in the universal secure verification flow allows an authenticated user with a registered passkey to satisfy secure verification without completing a WebAuthn assertion.
Affected versions
= v0.10.0
Description
The POST /api/verify endpoint supports multiple secure verification methods, including passkeys. When the request body contains {"method":"passkey"}, the server only checks whether the authenticated account has a passkey record on file and then marks the secure verification session as complete. It does not verify that the requester successfully completed a WebAuthn assertion.
As a result, an authenticated user who already has a valid session and a registered passkey can satisfy the secure verification requirement without performing the intended passkey challenge/response flow.
Impact
In the upstream project, this issue affects actions protected by SecureVerificationRequired(). At the time of publication, the confirmed upstream impact is the root-only POST /api/channel/:id/key endpoint, which returns stored channel secrets.
Successful exploitation requires:
- an already authenticated session for the target account, and
- a registered passkey on that account.
No full login bypass or cross-account privilege escalation has been confirmed in the upstream codebase. However, the issue defeats the intended step-up verification control for affected privileged actions.
Workarounds
Until a patched release is applied:
- do not rely on passkey as the step-up method for privileged secure-verification actions;
- require TOTP/2FA for those actions where operationally possible; or
- temporarily restrict access to affected secure-verification-protected endpoints.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/QuantumNous/new-api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of github.com/QuantumNous/new-api has shipped for CVE-2026-32879 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-32879 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-32879. 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-2026-32879 in your dependencies?
O3 Security finds CVE-2026-32879 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
