Security readout for executives and security teams
Plain-English summary
CVE-2026-27406 affects the WordPress My Tickets plugin by Joe Dolson, versions up to 2.1.0. It can expose sensitive information sent by the application. The issue is rated high because it is network-accessible, requires no login, and primarily impacts confidentiality.
Executive priority
Treat as a high-priority confidentiality issue for public WordPress sites using My Tickets. Prioritize sites handling attendee, customer, payment-adjacent, or event registration data. If no vendor-confirmed fix is available, reduce exposure by disabling unnecessary use and monitoring for vendor guidance.
Technical view
The CVE describes CWE-201, Insertion of Sensitive Information Into Sent Data, in My Tickets <= 2.1.0. CVSS 3.1 is 7.5 with AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. Public details do not specify the exact sensitive data, endpoint, or a fixed version.
Likely exposure
Exposure is limited to WordPress sites running the My Tickets plugin at version 2.1.0 or earlier. Risk is higher for public sites using the plugin for ticketing, registration, or event workflows that process customer or attendee data.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates remote, unauthenticated access with low attack complexity, but public sources provided do not include exploit details or proof-of-concept information.
Researcher notes
Evidence is sparse. The CVE and Patchstack entry identify a sensitive data exposure in My Tickets <= 2.1.0, but do not provide root-cause detail, affected data fields, exploit path, or confirmed fixed release in the supplied sources. Avoid assuming active exploitation or specific impact beyond confidentiality exposure.
Mitigation direction
- Inventory WordPress sites for the My Tickets plugin and record installed versions.
- If running <= 2.1.0, check vendor and Patchstack guidance for updates or remediation.
- Disable or remove the plugin where it is not business-critical.
- Limit collection and display of sensitive ticketing data until remediated.
- Review logs and affected workflows for unexpected exposure of customer or attendee data.
Validation and detection
- Confirm whether the My Tickets plugin is installed on each WordPress site.
- Verify the installed plugin version is greater than 2.1.0 or otherwise vendor-remediated.
- Use authorized testing to inspect plugin-generated output for unintended sensitive data.
- Check whether public pages, emails, or API responses include private ticketing information.
- Document affected sites, data types involved, and remediation status.
