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. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to be running the axiomthemes 69 Clothing WordPress theme at version 1.2.11.1 or earlier, with the theme active so its unauthenticated deserialization endpoint is reachable over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All available signals point to high real-world risk: the CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H describes network-reachable, low-complexity, unauthenticated exploitation with full confidentiality, integrity, and availability impact, yielding a 9.8 critical score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends a crafted HTTP request to the vulnerable 69 Clothing theme endpoint containing a malicious PHP serialized object designed to trigger a POP gadget chain present on the target site. When the theme calls unserialize() on this input, the object's magic methods execute, allowing the attacker to write or delete files, tamper with the database, or achieve code execution depending on available gadgets. … |
| Remediation | 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. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
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. …
