How do I fix CVE-2026-9586?

No fixed release is recorded for CVE-2026-9586 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

How do I detect CVE-2026-9586 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2026-9586 if there is no patch (or I can't update yet)?

Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.

Is CVE-2026-9586 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-9586 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-9586?

CVE-2026-9586 has an EPSS (Exploit Prediction Scoring System) score of 19.0%, placing it in the 97th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score warrants monitoring and prompt remediation.

Is CVE-2026-9586 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2026-9586 (Sangoma Switchvox SQL Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2026-09-02. CISA required all US federal civilian agencies to remediate this vulnerability by 2026-09-05. The required action was: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2026-9586?

CVE-2026-9586 is classified as SQL Injection (CWE-89). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for CVE-2026-9586?

A Nuclei detection template exists for CVE-2026-9586, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2026-9586 published, and has it been updated?

CVE-2026-9586 was published on July 17, 2026 and was last updated on September 3, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Actively Exploited: CVE-2026-9586: SQL Injection

Exploitation Status

Actively exploited in the wild

Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2026-09-02. Federal agencies were required to remediate by 2026-09-05.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.

Description

An unauthenticated SQL injection vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997). The /pa endpoint processes XML content beginning with <PolycomIPPhone> and directly concatenates the user-controlled PhoneIP value into PostgreSQL queries without sanitization or parameterization. An unauthenticated remote attacker can execute arbitrary SQL statements against the backend PostgreSQL database using a single crafted request, including database operations and remote code execution.

How to detect CVE-2026-9586

A community-maintained Nuclei template exists for this CVE. You can scan for it directly:

nuclei -id cve-2026-9586 -u https://target

Template: Sangoma Switchvox < 8.4.0.2 - Unauthenticated SQL Injection
Severity: critical
Impact: An unauthenticated remote attacker can achieve full remote code execution on the Switchvox server by injecting SQL via the PhoneIP XML field, leveraging PostgreSQL superuser privileges to execute arbitrary OS commands via COPY TO PROGRAM.
Remediation: Upgrade Sangoma Switchvox to version 8.4.0.2 or later which parameterizes the SQL query and validates the PhoneIP input.
