CVE-2025-60230
CRITICAL
Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Network-reachable and unauthenticated (AV:N/PR:N/UI:N), but reliable RCE depends on a usable POP gadget chain being present in the WordPress process, raising attack complexity to AC:H; full CIA impact retained.
Primary rating from Vendor (Patchstack).

Deserialization of Untrusted Data vulnerability in Themeton The Barber Shop allows Object Injection.
This issue affects The Barber Shop: from n/a through 1.9.
AnalysisAI
Unauthenticated PHP object injection in the Themeton 'The Barber Shop' WordPress theme (versions up to and including 1.9) allows remote attackers to deserialize attacker-controlled data, potentially leading to arbitrary code execution, file manipulation, or full site compromise when a usable POP gadget chain is present. The flaw was disclosed via Patchstack and carries a CVSS 3.1 score of 9.8, though no public exploit identified at time of analysis and EPSS data was not provided. The vulnerability is rooted in CWE-502 (Deserialization of Untrusted Data), a class historically abused for RCE in WordPress plugin/theme ecosystems.
Technical ContextAI
The Barber Shop is a commercial WordPress theme distributed by Themeton (CPE cpe:2.3:a:themeton:the_barber_shop). CWE-502 indicates the theme passes untrusted input (likely via a POST/GET parameter, cookie, or option value) into PHP's unserialize() without validation. In WordPress, this pattern is dangerous because the broader plugin/theme ecosystem loaded into the same PHP process frequently provides 'POP gadget' chains (objects with magic methods like __wakeup, __destruct, or __toString) that can be chained to achieve file writes, SQL execution, or arbitrary code execution. The 'Object Injection' label in the Patchstack advisory confirms this is the classic PHP unserialize sink rather than a JSON or XML deserialization issue.
RemediationAI
No vendor-released patch identified at time of analysis - the Patchstack entry describes the flaw as affecting versions up to 1.9 with no fixed version confirmed in the supplied data, so administrators should monitor the Themeton vendor page and the Patchstack advisory at https://patchstack.com/database/wordpress/theme/nrgbarbershop/vulnerability/wordpress-the-barber-shop-theme-1-9-php-object-injection-vulnerability for a 1.9.1+ release. Until a patched release is published, the most effective compensating control is to switch to a different theme (trade-off: significant visual/site rebuild work); alternatives include placing a WAF such as Patchstack, Wordfence, or ModSecurity in front of the site with rules to block serialized PHP objects (strings containing 'O:' or 'a:' followed by length:'Class':) in request parameters (trade-off: may break legitimate serialized inputs and requires tuning), restricting access to the theme's exploitable endpoint(s) once identified from the advisory, and disabling the theme entirely if it is not actively serving the production site. Generic WordPress hardening - keeping core and all other plugins/themes patched - reduces the availability of POP gadget chains needed to weaponize the bug.
