Summary

CVE-2026-13600 is an authentication bypass / improper authentication vulnerability (CWE-287) affecting the AutoNetTV Relay WordPress plugin. The plugin fails to perform any capability or authentication check before setting a WordPress administrator authentication cookie during its scheduled content-synchronization task, allowing an unauthenticated remote attacker to trigger that task and obtain administrator-level session credentials. The issue carries a CVSS v3.1 base score of 8.1 (High).

Technical details

  • Root cause: The plugin’s scheduled ("cron") content-synchronization routine sets a WordPress administrator authentication cookie without first verifying the caller’s identity, capability, or session state.
  • Trigger conditions: On certain server configurations, an unauthenticated attacker can directly invoke or trigger the scheduled sync task (e.g., by requesting the endpoint/hook responsible for the synchronization), causing the plugin to issue a valid admin auth cookie to the attacker.
  • Attack vector: Network — no authentication, privileges, or user interaction are required (AV:N, PR:N, UI:N), though the attack has high complexity (AC:H) since it depends on specific server/task-execution conditions being met.
  • Impact: Successful exploitation grants the attacker a WordPress administrator session, resulting in full compromise of confidentiality, integrity, and availability of the affected site (complete site takeover, including content modification, plugin/theme installation, and data exfiltration).

Affected software

  • AutoNetTV Relay WordPress plugin — all versions prior to 3.0.14

Severity

  • CVSS v3.1 Base Score: 8.1 (High)
  • Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade the AutoNetTV Relay plugin to version 3.0.14 or later, which adds the missing authentication/capability checks before the scheduled sync task sets the administrator cookie.
  • If unable to patch immediately:
    • Temporarily deactivate the AutoNetTV Relay plugin until the update can be applied.
    • Restrict or disable access to WordPress cron (wp-cron.php) execution from untrusted/external sources, and consider moving scheduled task execution to a server-side cron job that is not directly reachable over the network.
    • Monitor site access and admin logs for unexpected administrator logins or sessions originating from unfamiliar IP addresses, particularly correlated with cron/sync task execution.
    • Enforce a Web Application Firewall (WAF) rule set capable of detecting anomalous requests to plugin sync/cron endpoints.

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.
