CVE-2024-13410: Loftocean Cozystay - Hotel Booking WordPress Theme

Critical severity, CVSS 9.8. EPSS: 0.8% chance of exploitation in the next 30 days.

The CozyStay and TinySalt plugins for WordPress are vulnerable to PHP Object Injection in all versions up to, and including, 1.7.0, and in all versions up to, and including 3.9.0, respectively, via deserialization of untrusted input in the 'ajax_handler' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

Affected products

• Loftocean Cozystay - Hotel Booking WordPress Theme: up to and including 1.7.0
• Loftocean Tinysalt - Personal Food Blog WordPress Theme: up to and including 3.9.0
