Security readout for executives and security teams
Plain-English summary
CVE-2026-27095 affects the WordPress “Bus Ticket Booking with Seat Reservation” plugin. The reported flaw can let an unauthenticated remote attacker abuse unsafe data deserialization, with potential full confidentiality, integrity, and availability impact. Treat exposed WordPress sites using affected plugin versions as high-priority until verified patched or removed.
Executive priority
Prioritize within emergency WordPress risk handling for any internet-facing site using this plugin. The severity is critical and unauthenticated remote impact is reported, but active exploitation is not confirmed in the provided sources.
Technical view
The CVE describes CWE-502 deserialization of untrusted data leading to PHP object injection in magepeopleteam Bus Ticket Booking with Seat Reservation through version 5.6.0. CVSS 3.1 is 9.8: network exploitable, low complexity, no privileges, no user interaction, and high CIA impact.
Likely exposure
Public WordPress sites running the plugin at version 5.6.0 or earlier are the likely exposure. The supplied record does not identify specific vulnerable endpoints, required configuration, or a confirmed fixed version.
Exploitation context
The CVSS vector indicates unauthenticated remote exploitability without user interaction. The source bundle does not show CISA KEV listing or cited evidence of active exploitation. No exploit status beyond the vulnerability database entry is confirmed here.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The affected range is stated as through 5.6.0, while the Patchstack URL text references 5.6.2; do not infer a fixed version from the URL alone. No payloads, exploit details, or official remediation text are included in the bundle.
Mitigation direction
- Inventory WordPress sites for the affected plugin and version.
- Prioritize sites running version 5.6.0 or earlier.
- Check vendor and Patchstack guidance for a fixed version or official mitigation.
- If no safe update is available, disable or remove the plugin pending vendor guidance.
- Review backups and monitoring for affected WordPress sites.
Validation and detection
- Confirm installed plugin slug is bus-ticket-booking-with-seat-reservation.
- Record the installed plugin version from WordPress administration or asset inventory.
- Compare the version against the reported affected range through 5.6.0.
- Check logs for unusual unauthenticated requests to plugin-related paths.
- Verify any update or removal on a staging site before production rollout.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
