Summary

CVE-2025-68045 is a high-severity Unauthenticated Broken Access Control vulnerability in the WP Event Solution (Eventin) WordPress plugin by Arraytics, affecting all versions up to and including 4.1.12. Rooted in a missing authorization check (CWE-862), the flaw permits unauthenticated remote attackers to bypass access controls and perform privileged operations without any credentials. The vulnerability carries a CVSS v3.1 score of 7.5 (High) and was patched in version 4.1.13.

Technical details

  • Root cause: A missing authorization, authentication, or nonce token check within a plugin function that is expected to enforce access control before executing privileged actions — allowing unauthenticated requests to reach and trigger restricted functionality.
  • Trigger conditions: No authentication, no user interaction, and no special server configuration are required; any remote unauthenticated attacker can reach the affected endpoint over the network.
  • Attack vector: Network-accessible (AV:N, AC:L, PR:N, UI:N); exploitable from the internet against any WordPress site running the unpatched plugin.
  • Impact: High confidentiality impact (C:H) — unauthenticated attackers can access restricted data or invoke privileged plugin functionality that should require elevated permissions. Integrity and availability are not directly impacted by this vulnerability.

Affected software

  • WP Event Solution (Eventin) plugin by Arraytics — all versions ≤ 4.1.12

Severity

CVSS v3.1 Base Score: 7.5 (High)
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate: Update the WP Event Solution (Eventin) plugin to version 4.1.13 or later, which contains the vendor-provided fix.
  • If immediate patching is not feasible: Apply network-layer controls to restrict public access to WordPress REST API and administrative endpoints, or temporarily deactivate the plugin until the update can be applied.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

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.
