MITRE ATT&CK
2 techniques across 2 tactics: Execution, Initial Access The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Requires the target to be running the ThemeREX 'Nuts' WordPress theme at version 1.12 or earlier, with the vulnerable deserialization code path reachable by an unauthenticated remote request (per AV:N/PR:N/UI:N). The practical impact additionally depends on the presence of a usable PHP POP/gadget chain in the theme or co-installed plugins/core, which the available sources do not describe or confirm. Limiting factors: the affected product is a specific commercial theme rather than ubiquitous software, so exposure is bounded by how many sites run this theme; the exact input/feature that triggers unserialization is not stated in the available data. |
| Impact | Multiple severity signals align toward high priority but real-world risk is tempered by product footprint and thin exploitation data. The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) describes network-reachable, low-complexity, unauthenticated exploitation with high confidentiality, integrity and availability impact (9.8), and the vuln.today decision label is 'act_now', which argues for prompt remediation. CWE-502 (deserialization) combined with the 'PHP Object Injection' description means exploitation outcome typically hinges on available POP/gadget chains in the theme or co-installed plugins; the input does not describe the trigger or confirm a working chain, so the H/H/H impact is a plausible worst case rather than a demonstrated one. No EPSS score is supplied, so exploitation probability cannot be quantified; the vulnerability is NOT in CISA KEV; and the single reference is the Patchstack advisory, not a published proof-of-concept, so there is no confirmed public exploit. Net: a genuinely high-severity, unauthenticated flaw worth patching quickly per the act_now label, but the absence of EPSS, KEV, and any PoC - together with a niche WordPress theme footprint - suggests this is a serious-but-not-yet-widely-weaponized issue rather than a mass-exploitation emergency. Verify fixed version with ThemeREX/Patchstack, as the input lists only affected versions (<= 1.12) and no fix. |
| Exploit ScenarioDerived | A remote attacker sends a crafted request to a WordPress site running the ThemeREX 'Nuts' theme (version 1.12 or earlier) containing a serialized PHP object in an input the theme deserializes, without needing any authentication. If a usable gadget (POP) chain exists in the theme or other installed code, deserialization can escalate to actions such as file operations, data disclosure, or remote code execution. No public exploit code is identified in the provided data, and the exact trigger is not described in the available sources. |

Alert meAnalysisAIv1 – Oct 29, 2026
Unauthenticated PHP object injection in the ThemeREX 'Nuts' WordPress theme (versions up to and including 1.12) lets remote attackers pass crafted serialized data into a PHP unserialize() path without any credentials, rated CVSS 9.8 (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:H) by the reporter. Actual exploitation success is conditional: the practical impact depends on a usable POP/gadget chain being present in the theme or in co-installed plugins or WordPress core, and the available sources do not confirm such a chain or identify the exact request/feature that reaches the deserialization sink. No public exploit code is confirmed and the CVE is not in CISA KEV, although the vuln.today decision label is act_now, so this should be treated as a high-priority patch item for sites running the theme rather than as an actively exploited emergency.
RemediationAI
No vendor-released patch version is identified in the available data, so the first step is to check the ThemeREX customer area and the Patchstack advisory (https://patchstack.com/database/wordpress/theme/nuts/vulnerability/wordpress-nuts-theme-1-12-php-object-injection-vulnerability?_s_id=cve) for a fixed theme build, and upgrade as soon as one is published. Until a fixed build is confirmed, the highest-value action is to remove or deactivate the Nuts theme on any site that does not require it - the trade-off is loss of the site's themed presentation, so a staging copy should be retained - because deactivating the theme removes the vulnerable code path entirely; where the theme must stay live, reducing the gadget surface by removing unused plugins and bundled libraries with known unserialize() magic-method chains limits, but does not eliminate, the chance that object injection converts into code execution, and this is a probabilistic control rather than a fix. No vendor-documented workaround or WAF signature for this specific issue is provided in the supplied references, so any virtual patching rule must be written against the site's own traffic once the vulnerable endpoint is identified.

Technical ContextAI · show details
The flaw is a CWE-502 Deserialization of Untrusted Data case in a PHP-based WordPress theme. WordPress themes routinely accept request parameters and, in vulnerable code paths, feed attacker-influenced values into PHP's unserialize(), which can instantiate arbitrary classes and invoke magic methods (__wakeup, __destruct, __toString). Whether that object injection escalates to file writes, code execution or data disclosure depends entirely on the classes autoloadable in the target installation - i.e., on a POP/gadget chain supplied by the theme itself, a bundled library, another plugin or core. The CPE cpe:2.3:a:themerex:nuts:*:*:*:*:*:*:*:* identifies the affected component as the ThemeREX 'Nuts' theme across all versions, with the advisory scoping the flaw to 1.12 and earlier; because the theme is commercial and distributed outside the wordpress.org repository, the vulnerable unserialize() call site and the triggering request are not described in the available sources, so the precise mechanism by which input reaches the sink is unverified.

Executive ViewAI
Sites running the ThemeREX 'Nuts' WordPress theme (versions up to and including 1.12) carry an unauthenticated critical-severity flaw that allows remote attackers to inject serialized data into a PHP deserialization path. While the vulnerability is rated 9.8 and warrants prompt remediation, no public exploit code is confirmed and it is not known to be actively exploited, so leadership should prioritize scheduled patching rather than emergency response. Any organization hosting WordPress sites with this theme should treat this as a high-priority maintenance item given the unauthenticated attack surface.
No vendor-released patch identified at time of analysis; interim mitigations include deactivating or removing the vulnerable theme, upgrading to a maintained alternative theme, deploying WAF rules to block crafted serialized payloads, minimizing installed plugins to reduce gadget-chain availability, and restricting administrative exposure where possible.
