Which versions of 69 Clothing are affected by EUVD-2026-53989?

The 69 Clothing WordPress theme (versions ≤1.2.11.1) contains a critical unauthenticated object injection vulnerability (CVSS 9.8) enabling remote code execution on any affected site without a valid…

How to fix or mitigate EUVD-2026-53989?

Within 24 hours, audit all WordPress installations to identify those running 69 Clothing theme version 1.2.11.1 or earlier and confirm their internet-facing status; immediately deactivate the theme and switch to an alternative (WooCommerce default theme or equivalent) to remove the attack surface. Within 7 days, complete theme migration on all production sites and configure WAF rules blocking PHP-serialized payloads as interim protection. Within 30 days, verify all sites are on alternative themes, apply the vendor patch if released, and monitor Patchstack advisory EUVD-2026-53989 for remediation updates.

DescriptionCVE.org

Unauthenticated PHP Object Injection in 69 Clothing <= 1.2.11.1 versions.

AnalysisAI

Unauthenticated PHP Object Injection in the 69 Clothing WordPress theme (versions up to and including 1.2.11.1) lets remote attackers submit crafted serialized data that is unsafely deserialized, potentially triggering property-oriented programming (POP) gadget chains for code execution, data theft, or file manipulation. Reported by Patchstack and tracked as EUVD-2026-53989, it carries a critical CVSS 9.8 with no authentication required. There is no public exploit identified at time of analysis, but the network-reachable, unauthenticated nature makes it a high-priority patching target for any WordPress site running this theme.

Technical ContextAI

The vulnerability is a CWE-502 Deserialization of Untrusted Data flaw affecting the axiomthemes '69 Clothing' commercial WordPress theme (CPE cpe:2.3:a:axiomthemes:69_clothing). PHP Object Injection occurs when attacker-controlled input reaches PHP's unserialize() function; the attacker can instantiate arbitrary PHP objects whose magic methods (__wakeup, __destruct, __toString) fire automatically. When a suitable POP gadget chain exists in the theme, its bundled plugins, or the broader WordPress core/plugin ecosystem loaded alongside it, this can escalate to arbitrary file writes/deletes, SQL injection, or remote code execution. The 'Deserialization/PHP' tags confirm the mechanism, and the unauthenticated vector implies the vulnerable unserialize sink is reachable through a public request handler (e.g., an AJAX action or unauthenticated form/import endpoint) exposed by the theme.

RemediationAI

The input does not include a confirmed fixed version, so no vendor-released patch version can be cited - no vendor-released patch identified at time of analysis; monitor the Patchstack advisory (https://patchstack.com/database/wordpress/theme/clothing69/vulnerability/wordpress-69-clothing-theme-1-2-11-1-php-object-injection-vulnerability) and the axiomthemes/ThemeForest changelog for a release above 1.2.11.1 and upgrade as soon as it is available. Until a patched version ships, apply compensating controls: deploy a WAF/virtual patch (Patchstack offers one) to block requests containing PHP serialized-object payloads (patterns like 'O:' and 'a:' in POST bodies) reaching the theme's endpoints; identify and restrict or disable the unauthenticated theme endpoint that performs deserialization (for example the specific admin-ajax action or import/form handler), accepting that this may break the associated theme feature; and consider temporarily switching to a different theme on high-value sites, understanding this changes site appearance. Also audit installed plugins to reduce available POP gadget chains, since removing gadget sources lowers exploitability even before a patch.
