Gutentype
Monthly
PHP object injection in the ThemeREX Gutentype WordPress theme (all versions through 2.1.12) allows remote, unauthenticated attackers to inject arbitrary PHP objects through unsafe deserialization of untrusted data, with the potential for full confidentiality, integrity, and availability impact if a usable gadget chain is reachable. The supplied CVSS 3.1 vector scores 9.8 (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:H), but the independent assessment rates attack complexity as High because practical exploitation depends on the presence of a suitable POP gadget chain in the theme, WordPress core, or an installed plugin - without one, real-world impact is likely lower than the base score implies. No public exploit code has been identified at time of analysis, and the flaw is not confirmed as actively exploited (no CISA KEV listing); exploitation is bounded to sites running the Gutentype theme, unpatched, at version 2.1.12 or earlier.
