Summary

CVE-2026-27089 is a high-severity Unauthenticated Bypass vulnerability (CWE-290: Authentication Bypass by Spoofing) in the WpTravelly plugin for WordPress, developed by Magepeople Inc. It affects all versions up to and including 2.1.7 and carries a CVSS v3.1 base score of 7.5 (HIGH). The flaw allows unauthenticated remote attackers to circumvent the plugin’s authentication and authorization controls, resulting in a HIGH integrity impact — meaning unauthorized modification of site data is possible without any valid credentials or user interaction.

Technical details

  • Root cause: The vulnerability is classified as CWE-290 (Authentication Bypass by Spoofing), meaning the plugin fails to adequately verify the identity or authorization of a requestor, allowing an unauthenticated actor to satisfy authentication checks through a spoofed or forged request.
  • Attack vector: Fully remote and unauthenticated — exploitable over the network with no privileges and no user interaction required (AV:N/AC:L/PR:N/UI:N).
  • Impact: HIGH integrity impact (I:H); no confidentiality or availability impact. Successful exploitation enables unauthorized write-level actions against the affected WordPress site — such as manipulating tour listings, booking data, or other plugin-controlled content — without any valid account.
  • Pattern of access-control weaknesses: Public vulnerability databases record multiple prior authorization flaws in this plugin, including broken access control (CVE-2024-43212, CVE-2026-27331), PHP object injection (CVE-2025-30892), and local file inclusion (CVE-2025-30891), reflecting a recurring pattern of insufficient access controls across plugin versions.
  • Discovery: Reported by security researcher benzdeus and published June 15, 2026.

Affected software

  • WpTravelly (tour-booking-manager) by Magepeople Inc. — all versions ≤ 2.1.7

Severity

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

Mitigation and recommended actions

  • Immediate: Update WpTravelly to version 2.1.8 or later (current version is 2.1.9). The fix was first introduced in version 2.1.8.
  • Administrators who cannot immediately upgrade should consider restricting access to WordPress AJAX endpoints associated with the plugin (ttbm_ajax_url) at the web server or WAF level as a temporary measure until the plugin is updated.
  • Review recent unauthorized changes to tour listings, bookings, or site content on affected installations.

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.
