Summary
CVE-2025-11755 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Wordpress (inferred from references). Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 44.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
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.
Advisories, including Wordfence's threat intelligence report at https://www.wordfence.com/threat-intel/vulnerabilities/id/603210ca-7231-4c91-8258-fe3cd6e37425?source=cve, provide further details on the issue. The vulnerable code in the REST import controller is visible in the WordPress plugin trac at https://plugins.trac.wordpress.org/browser/delicious-recipes/trunk/src/api/inc/endpoints/class-delicious-recipes-rest-import-recipe-terms-controller.php.

Mitigating Controls (NIST 800-53 r5) AI
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.
Information input validation ensures files fetched from remote URLs during recipe imports are checked for dangerous types like PHP, blocking unrestricted uploads.
Malicious code protection mechanisms scan and quarantine uploaded PHP files containing exploits or webshells before they enable RCE.
