Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Remediating the arbitrary file upload flaw in WP Delicious plugin versions up to 1.9.0 by applying vendor patches directly prevents exploitation via malicious PHP uploads during CSV recipe imports.

SI-10 Information Input Validation good match

prevent

Information input validation ensures files fetched from remote URLs during recipe imports are checked for dangerous types like PHP, blocking unrestricted uploads.

SI-3 Malicious Code Protection good match

preventdetect

Malicious code protection mechanisms scan and quarantine uploaded PHP files containing exploits or webshells before they enable RCE.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

T1505.003 Web Shell Persistence

Adversaries may backdoor web servers with web shells to establish persistent access to systems.

Why these techniques?

The vulnerability enables exploitation of a public-facing WordPress plugin (T1190), allows low-privileged users (Contributor) to achieve RCE implying privilege escalation (T1068), and facilitates uploading PHP web shells (T1505.003).

NVD Description

The WP Delicious – Recipe Plugin for Food Bloggers (formerly Delicious Recipes) plugin for WordPress is vulnerable to arbitrary file uploads when importing recipes via CSV in all versions up to, and including, 1.9.0. This flaw allows an attacker with…

at least Contributor-level permissions to upload a malicious PHP file by providing a remote URL during a recipe import process, leading to Remote Code Execution (RCE).

Deeper analysisAI

CVE-2025-11755 is an arbitrary file upload vulnerability in the WP Delicious – Recipe Plugin for Food Bloggers (formerly Delicious Recipes) plugin for WordPress, affecting all versions up to and including 1.9.0. The flaw occurs during CSV-based recipe imports, where the plugin fails to properly validate files fetched from remote URLs, allowing malicious PHP files to be uploaded. Published on 2025-11-01, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-434 (Unrestricted Upload of File with Dangerous Type).

Attackers with at least Contributor-level permissions can exploit this vulnerability by supplying a remote URL pointing to a malicious PHP file during the recipe import process via the plugin's REST API endpoint. Successful exploitation leads to remote code execution (RCE) on the targeted WordPress site, potentially granting full server compromise depending on the uploaded payload and server configuration.
