IONIX Platform Capabilities & Workflow

What is Preemptive Exposure Mitigation (PEM) and how does IONIX deliver it?

Preemptive Exposure Mitigation (PEM) is IONIX's strategic approach to external exposure management. IONIX discovers an organization's full external attack surface—including unknown assets, subsidiaries, and digital supply chain dependencies—validates which exposures are actually exploitable, and mitigates them before attackers can act. The workflow follows five steps: DISCOVER, VALIDATE, PRIORITIZE, MITIGATE, and VERIFY. IONIX operates across the CTEM (Continuous Threat Exposure Management) lifecycle at machine speed, with humans governing policy and agents operating. Note: PEM focuses on external exposures; internal asset management is not included.

How does IONIX discover unknown assets and digital supply chain dependencies?

IONIX uses Connective Intelligence to recursively map all internet-facing assets, including shadow IT, subsidiaries, and third- and nth-party digital supply chain dependencies. Discovery is agentless and starts from the internet, not from internal inventories. This approach ensures that assets outside existing scanner coverage are identified. Note: Internal-only assets not exposed to the internet are not discovered by IONIX.

What is exposure validation and how does IONIX perform it?

Exposure validation is the process of actively testing whether an identified exposure is exploitable from outside the perimeter, as an attacker would. IONIX transforms real-world proof-of-concept exploits into safe, non-intrusive test payloads and executes them only against assets that match the vulnerable criteria. This ensures that only validated, actionable exposures are prioritized for mitigation. Note: IONIX does not perform internal vulnerability scanning or penetration testing.

How does IONIX prioritize and mitigate exposures?

IONIX prioritizes exposures based on asset criticality, exploitability, and blast radius. The platform bundles issues into remediation clusters and routes them through integrations with ticketing, SOAR, and SIEM tools. Action items are written in plain language and prioritized for rapid mitigation, shortening mean time to remediation (MTTR). Note: Prioritization is based on external exposure and validated exploitability; internal context may require additional review.

What is Live Exposure Defense and what is the 12-hour SLA?

Live Exposure Defense is an IONIX capability that commits to identifying every potentially affected asset within 12 hours of CVE publication, with exploitability validation running inside the same window. This enables organizations to respond to zero-days and emerging threats at machine speed. Note: The 12-hour SLA applies to external, internet-facing assets; internal assets may require additional assessment.

Does IONIX require agents or sensors to operate?

No, IONIX is agentless. Discovery and validation start from the internet, requiring no deployment of agents or sensors on your infrastructure. This enables rapid onboarding and continuous coverage of external exposures. Note: Internal-only assets not exposed to the internet are not covered by IONIX.

Integration & Automation

What integrations does IONIX support for remediation workflows?

IONIX integrates with ticketing platforms (Jira, ServiceNow), SIEM providers (Splunk, Microsoft Azure Sentinel), SOAR platforms (Cortex XSOAR), collaboration tools (Slack), and cloud security platforms (Wiz, Palo Alto Prisma Cloud).

CVE-2026-56303 – Unauthenticated API Key Metadata Disclosure – Capgo before 12.128.2

Be the first to know when new zero-days emerge:

Summary

CVE-2026-56303 is a high-severity information disclosure vulnerability in Capgo, an open-source live update platform for Ionic/Capacitor mobile applications. The flaw resides in the find_apikey_by_value PostgreSQL function, which is marked SECURITY DEFINER and granted execution rights to the unauthenticated anon database role, exposing sensitive API key metadata to any remote attacker via an unauthenticated REST endpoint. The vulnerability is rated CVSS 4.0: 8.7 (High) and was addressed in version 12.128.2.

Technical details

  • Root cause: The find_apikey_by_value PostgreSQL function is marked SECURITY DEFINER, meaning it executes with the elevated privileges of its definer rather than the calling user. Execution rights on this function are granted to the anon role — the role used by PostgREST for unauthenticated connections — with no authentication token required.
  • Trigger conditions: An attacker sends an unauthenticated POST request to /rest/v1/rpc/find_apikey_by_value supplying a valid API key value as the function parameter. Possession of a valid API key value is the only prerequisite, making this a targeted rather than opportunistic exploit.
  • Attack vector: Network-accessible HTTP POST to the PostgREST RPC endpoint on any internet-facing self-hosted Capgo deployment. No authentication header or session token is required.
  • Impact: A successful call returns sensitive API key metadata, including the associated user_id, key mode, organizational scoping, and expiration details (CVSS VC:H). This data can be chained with other unauthenticated Capgo RPC endpoints — such as get_orgs_v6 and get_identity_apikey_only, also fixed in version 12.128.2 — to enumerate organization memberships, management email addresses (PII), roles, and subscription metadata, enabling further unauthorized access or privilege escalation. Multiple related CVEs were disclosed simultaneously (CVE-2026-56235, CVE-2026-56242, CVE-2026-56243, CVE-2026-56316), reflecting systematic research that confirms a broad unauthenticated attack surface across Capgo’s PostgREST API layer.

Affected software

  • Capgo — all versions prior to 12.128.2 (self-hosted deployments exposing the PostgREST REST API to the internet)

Severity

  • CVSS v4.0: 8.7 (High) — CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
  • CVSS v3.1: 7.5 (High) — AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
  • CWE: CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor

Mitigation and recommended actions

  • Immediate: Upgrade to Capgo version 12.128.2 or later, which revokes the EXECUTE privilege on the affected SECURITY DEFINER functions from the anon role.
  • If immediate patching is not possible: Restrict public network access to the PostgREST /rest/v1/rpc/ path at the firewall or reverse proxy level. Additionally, revoke EXECUTE rights on find_apikey_by_value (and related SECURITY DEFINER functions) from the anon database role directly. Review and rotate any API keys that may have been queried or disclosed.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
