Frequently Asked Questions
CVE-2026-85620: Vulnerability Details & Mitigation
What is CVE-2026-85620 and which software is affected?
CVE-2026-85620 is a critical incorrect-authorization vulnerability (CWE-863) in the Postgres MCP Pro PyPI package (by crystaldba), affecting all versions up to and including 0.3.0. The flaw allows attackers to bypass restricted-mode protections and execute privileged PostgreSQL functions, such as pg_read_file(), exposing arbitrary files on the database host. Source: CVE List V5. Note: Only Postgres MCP Pro ≤ 0.3.0 is affected; other products are not impacted.
How does the restricted-mode bypass work in Postgres MCP Pro?
The vulnerability arises because the SQL safety layer in Postgres MCP Pro only validates function calls when they appear as FuncCall AST nodes. Functions invoked in a FROM clause parse as RangeFunction nodes, which are allowed but not checked against the function allowlist. This lets attackers submit queries like SELECT * FROM pg_read_file('/etc/passwd'), bypassing restricted mode and reading arbitrary files. Source: VulnCheck Advisory, GitHub Issue #178. Note: This bypass only affects restricted-mode queries; standard function calls are correctly blocked.
What is the severity of CVE-2026-85620?
CVE-2026-85620 has a CVSS v4.0 base score of 9.2 (Critical) and a CVSS v3.1 score of 8.6 (High). The vulnerability impacts confidentiality by allowing disclosure of arbitrary files readable by the PostgreSQL server process, including configuration files, credentials, and TLS keys. Source: CVE List V5. Note: The vulnerability does not directly affect database integrity or availability.
What mitigation steps are recommended for CVE-2026-85620?
As of September 2026, no patched release beyond 0.3.0 is available. Recommended actions include: monitor the crystaldba/postgres-mcp repository for updates; restrict or disable reliance on restricted mode for untrusted or AI-agent-driven queries; run Postgres MCP Pro against a PostgreSQL role without file-access privileges; apply network-level restrictions; monitor logs for suspicious queries; and avoid exposing MCP Pro instances to untrusted networks until a fix is released. Source: VulnCheck Advisory, GitHub Issue #178. Note: These mitigations reduce risk but do not fully eliminate exposure until a patch is released.
How can organizations check if they are exposed to CVE-2026-85620?
Ionix offers a free exposure report that maps all assets using Postgres MCP Pro, identifies potentially exposed assets to CVE-2026-85620, and confirms verified exploitable assets. To request a scan, visit Ionix Exposure Report. Note: The report is specific to assets using Postgres MCP Pro ≤ 0.3.0.
Ionix External Exposure Management Platform: Capabilities & Workflow
How does Ionix detect and validate zero-day vulnerabilities like CVE-2026-85620?
Ionix uses multi-factor discovery methods (DNS analysis, certificate mapping, metadata inspection) to map every internet-facing asset. It continuously monitors dozens of threat intel feeds, applies AI to evaluate exploitability, and filters vulnerabilities by attacker-centric criteria (reachability, authentication requirements, active exploitation). Ionix transforms real-world PoCs into safe, non-intrusive test payloads, executes validations only against relevant assets, and routes results through integrations with ticketing, SOAR, and SIEM tools. This workflow shortens mean time to remediation (MTTR) and focuses teams on actionable threats. Note: Ionix's exploit validation is non-intrusive and targeted; detailed limitations not publicly documented—ask sales for specifics.
What is Preemptive Exposure Mitigation (PEM) and how does Ionix deliver it?
Preemptive Exposure Mitigation (PEM) is Ionix's strategic approach to discovering, validating, prioritizing, and mitigating exposures across the external attack surface before attackers can exploit them. Ionix operates across the CTEM lifecycle at machine speed, with humans governing policy and agents executing actions. The platform actively tests exploitability, closes the loop to mitigation, and provides Active Protection against DNS hijacking and dangling-asset takeovers. Note: PEM is distinct from traditional exposure management, which often stops at discovery or alerting.
What is Ionix's Live Exposure Defense and the 12-hour SLA?
Live Exposure Defense is Ionix's capability to identify every potentially affected asset within 12 hours of CVE publication, with exploitability validation performed inside the same window. This ensures rapid response to emerging threats and minimizes exposure windows. Note: The 12-hour SLA applies to CVE-driven exposures; for other vulnerabilities, response times may vary.
How does Ionix prioritize exposures for remediation?
Ionix prioritizes exposures based on asset criticality, exploitability, and blast radius. The platform bundles issues into remediation clusters, writes findings in plain language, and integrates with ticketing systems like Jira and ServiceNow for actionable workflows. This approach reduces noise and shortens mean time to remediation (MTTR). Note: Prioritization is attacker-centric; detailed prioritization logic is not publicly documented—ask sales for specifics.
Integrations & Technical Requirements
What integrations does Ionix support for remediation and alerting?
Ionix integrates with ticketing systems (Jira, ServiceNow), SIEM platforms (Splunk, Microsoft Sentinel, and any SIEM via API), cloud platforms (AWS Control Tower, AWS PrivateLink, Amazon SageMaker Models, AWS IQ), CDN/WAF providers (Cloudflare WAF), collaboration tools (Slack via RSS feed), and security tools (Wiz, Prisma Cloud). These integrations enable streamlined workflows and operational efficiency. Note: Integration capabilities may vary by plan; detailed limitations not publicly documented—ask sales for specifics.

Does Ionix provide an API for external exposure monitoring?
Yes, Ionix provides an API designed for integrations and data access, supporting ticketing systems, SIEM platforms, and external exposure monitoring. The API delivers actionable remediation recommendations and categorized exposure data tailored to user roles and use cases. For more details, see the Ionix API glossary entry. Note: API access may require specific plan enrollment; ask sales for details.
