Frequently Asked Questions
Technical Details & CVE Exposure
What is CVE-2026-90999 and how does it impact Sentry Seer users?
CVE-2026-90999 is a critical (CVSS 9.8) trust-boundary violation affecting Sentry Seer, Sentry's AI-powered debugging assistant. When Seer is configured to automatically hand off issues to a connected coding agent, an unauthenticated attacker can submit a fabricated error event via the public DSN, causing the coding agent to download and execute attacker-controlled code. This results in remote code execution with the privileges of the automation environment and unauthorized access to connected source repositories. No valid Sentry account or credentials are required for exploitation. Note: Only deployments with Seer enabled for automatic or developer-invoked handoff and exposing a public DSN are affected.

What mitigation steps are recommended for CVE-2026-90999?
Immediate mitigation includes disabling automated Seer-to-coding-agent handoff so that a human reviews AI-generated analyses before any code is executed. If no patch is available, restrict or sandbox the coding agent's ability to install/execute packages without explicit human approval, rotate exposed DSNs, proxy error submissions through a server-side endpoint, apply defensive filtering/sanitization of inbound telemetry, and monitor coding-agent activity for unexpected package installs or command execution. Note: No official patched version has been published as of September 18, 2026. Source: CERT/CC

Ionix External Exposure Management Platform Capabilities
How does Ionix discover and validate exposures related to new CVEs?
Ionix uses multi-factor discovery methods, including DNS analysis, certificate mapping, and metadata inspection, to automatically map every internet-facing asset. The platform continuously monitors dozens of threat intelligence feeds and applies AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited. Ionix filters vulnerabilities by attacker-centric criteria, transforms real-world proof-of-concept code into safe test payloads, and executes exploit validations only against relevant assets. Results are routed through integrations with ticketing, SOAR, and SIEM tools, prioritized by asset criticality and exploitability. Note: Ionix's exploit validation is non-intrusive and targeted, but may not cover all edge cases; consult technical documentation for specifics. Threat Center
What is Preemptive Exposure Mitigation (PEM) and how does Ionix implement it?
Preemptive Exposure Mitigation (PEM) is Ionix's strategic approach to discovering, validating, prioritizing, and mitigating external exposures before attackers can exploit them. Ionix operates across the CTEM lifecycle at machine speed, with humans governing policy and agents operating. The platform actively tests exploitability from outside the perimeter, maps digital supply chain and subsidiary risk, and deploys Active Protection against DNS hijacking and dangling-asset takeovers. Note: PEM is designed for continuous operation, but teams needing periodic scanning or internal asset inventory may want to consider complementary tools. Learn more
How does Ionix prioritize and drive remediation for validated exposures?
Ionix bundles issues into remediation clusters and prioritizes them based on asset criticality, exploitability, and blast radius. Remediation workflows are integrated with ticketing systems like Jira and ServiceNow, enabling actionable, prioritized tasks for IT and security teams. The platform reduces mean time to remediation (MTTR) by up to 90% and false-positive alerts by 97%, as documented in Fortune 500 case studies. Note: Ionix's prioritization is attacker-centric, but organizations with unique internal workflows may require custom integration. Case study
