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 | Exploitation requires a site running the ThemeRex Good Homes theme at version 1.3.13 or earlier, reachable over the network. The flaw is unauthenticated (PR:N) with no user interaction, so no login is needed against affected installs. The practical limiting factor is that PHP Object Injection only produces meaningful impact when a usable POP gadget chain is present in the theme, a plugin, or WordPress core - the available sources do not confirm such a chain, nor do they name the specific vulnerable input/parameter that reaches unserialize(); the trigger is not described in the available sources. |
| Impact | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) describes a network-reachable, low-complexity, unauthenticated flaw with high impact to confidentiality, integrity, and availability, yielding the 9.8 base score. The vuln.today decision label is act_now and the report originates from Patchstack, a credible WordPress-focused source. However, several escalation signals are MISSING: there is no EPSS probability in the input, and KEV status is not indicated (treat as not listed), so this is not confirmed as actively exploited. No verified working exploit code is supplied - only a Patchstack database reference. A key mechanistic caveat: PHP Object Injection (CWE-502) only reaches the CVSS-rated C:H/I:H/A:H when a usable POP gadget chain is present in the theme or a loaded plugin/core; the available sources do not state whether such a chain exists here, so the full 9.8 impact is the rated ceiling rather than a confirmed outcome. Net: this is a credible high-priority item given act_now and unauthenticated network reach, but the real-world weaponization depends on gadget availability that the evidence does not confirm. |
| Exploit ScenarioDerived | A remote, unauthenticated attacker submits a crafted serialized PHP payload to an input on a site running the Good Homes theme (<= 1.3.13) that is passed to unserialize(). If a suitable POP gadget chain is reachable, deserialization triggers it, potentially leading to code execution, file operations, or data manipulation. A public PoC reference exists (Patchstack database entry); it is not verified as working exploit code in the available sources. |

Alert meAnalysisAIv1 – Oct 29, 2026
Unauthenticated PHP object injection in the ThemeRex Good Homes WordPress theme through version 1.3.13 can allow remote attackers to supply serialized data that may cause high confidentiality, integrity, and availability impact if a usable POP gadget chain exists in the theme, an installed plugin, or WordPress core. The CVSS 3.1 score is 9.8 with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, and vuln.today assigns an act_now priority. The provided data does not identify public exploit code or confirm CISA KEV active exploitation, and it does not confirm that a usable gadget chain or the specific vulnerable input is present.
RemediationAI
No vendor-released patch or exact fixed version is identified in the provided data, so verify the Patchstack advisory at https://patchstack.com/database/wordpress/theme/good-homes/vulnerability/wordpress-good-homes-theme-1-3-13-php-object-injection-vulnerability?_s_id=cve and apply an updated Good Homes release from ThemeRex if one is published. If no patched release is available, reduce exposure by temporarily switching the site to a maintained theme, with the side effect of layout and functionality changes, or by placing the site behind an IP allowlist or authentication layer, which breaks public access. A WAF rule that blocks requests containing PHP serialized-object markers can reduce attempts to reach a deserialization sink, but it may produce false positives on legitimate serialized data and cannot guarantee protection against bypass.

Technical ContextAI · show details
The affected product is the ThemeRex Good Homes WordPress theme, identified by CPE cpe:2.3:a:themerex:good_homes:*:*:*:*:*:*:*:*; the wildcard version field aligns with the reported affected range through 1.3.13. CWE-502 describes deserialization of untrusted data, which in PHP commonly involves passing attacker-influenced serialized input to an unsafe deserialization path such as unserialize(). Exploitation does not by itself guarantee code execution or data compromise: PHP object injection produces meaningful impact only when a usable POP gadget chain is available in the theme, another installed plugin, or WordPress core, and the available sources do not confirm such a chain. The sources also do not identify the specific request parameter or code path that reaches the deserialization sink, so the trigger is not described in the available data. The assessed CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, consistent with a network-reachable, low-complexity, unauthenticated issue with high potential impact.

DescriptionCVE.org
Unauthenticated PHP Object Injection in Good Homes <= 1.3.13 versions.
Executive ViewAI
CVE-2026-62017 presents a critical risk to our WordPress environment through the ThemeRex Good Homes theme (versions up to 1.3.13). This unauthenticated PHP object injection vulnerability could allow an attacker to compromise the confidentiality, integrity, and availability of our website and potentially back-end systems. Leadership should prioritize remediation because exploitation could lead to data breaches, service disruption, and reputational damage, and no vendor patch is currently available.
No vendor patch available. Interim mitigations: disable or remove the vulnerable theme; deploy WAF rules to detect/block PHP object injection attempts; restrict file permissions and user roles; monitor logs for suspicious serialized data; conduct regular security scans.
