CVE-2026-49770Network attack vectorHinoki check available

Object injection via untrusted session deserialization

Published Jun 15, 2026 · Updated Jun 15, 2026

PHP object injection in WP Travel Engine 6.7.12 and earlier allows remote attackers to inject objects through unauthenticated session data. The plugin's session-data handler deserializes attacker-controlled session content without preventing PHP object instantiation. Follow-on file deletion, sensitive-data access, or code execution requires a suitable POP chain from another installed plugin or theme; no chain is known in WP Travel Engine itself.
