Unauthenticated PHP Object Injection in Nifty <= 1.4.1 versions.
Articles & Coverage 1
AnalysisAI
Unauthenticated PHP Object Injection in BoldThemes Nifty WordPress theme versions 1.4.1 and earlier allows remote attackers to inject arbitrary PHP objects through unsafe deserialization, potentially leading to remote code execution when a suitable gadget chain exists in the WordPress installation. No public exploit identified at time of analysis, but the unauthenticated network-reachable nature combined with CVSS 9.8 makes this a high-priority issue for any site running the affected theme. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Target site must be running the BoldThemes Nifty WordPress theme at version 1.4.1 or earlier with the vulnerable theme endpoint reachable over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H signals a worst-case profile: network-reachable, low complexity, no authentication, no user interaction, with high impact across confidentiality, integrity, and availability - consistent with unauthenticated PHP Object Injection. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends an HTTP request to a public Nifty theme endpoint with a crafted serialized PHP payload in a parameter, cookie, or header that the theme passes to unserialize(). The deserialization instantiates objects chosen from a POP gadget chain present in WordPress core or other installed plugins, triggering magic methods that write a PHP webshell to the uploads directory or execute arbitrary code, giving the attacker full control of the WordPress site. |
| Remediation | No vendor-released patch identified at time of analysis; the EUVD entry lists the affected range as '≤1.4.1' without naming a fixed version, so administrators should monitor the BoldThemes vendor channel and the Patchstack advisory at https://patchstack.com/database/wordpress/theme/nifty/vulnerability/wordpress-nifty-theme-1-4-1-php-object-injection-vulnerability for a fixed release and upgrade as soon as one is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all WordPress instances using BoldThemes Nifty v1.4.1 or earlier; immediately disable and remove the theme; restore from clean backup if available. …
