Published: 11 March 2026
Summary
CVE-2026-2466 is a high-severity Cross-site Scripting (CWE-79) vulnerability. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 14.4th percentile by exploit likelihood (below the median); 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-15 (Information Output Filtering).
Deeper analysis
CVE-2026-2466 is a reflected cross-site scripting (XSS) vulnerability in the DukaPress WordPress plugin for versions through 3.2.4. The flaw arises because the plugin fails to sanitize and escape a parameter before outputting it back in the page, allowing malicious scripts to be injected and executed in a user's browser. It is classified under CWE-79 (Cross-Site Scripting) with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating high severity due to its network accessibility, low complexity, lack of required privileges, user interaction requirement, and changed scope.
Unauthenticated attackers can exploit this vulnerability by crafting a malicious URL containing a reflected XSS payload and tricking a targeted high-privilege user, such as an administrator, into interacting with it, for example by clicking a phishing link. Successful exploitation executes arbitrary JavaScript in the victim's browser context with the site's privileges, potentially enabling session hijacking, theft of sensitive data like admin credentials, or further actions like modifying site content or installing additional malware.
The WPScan advisory at https://wpscan.com/vulnerability/2843e8fe-0c02-48ee-ada3-f1c3d1ee73eb/ details the vulnerability and serves as the primary reference for affected installations. Security practitioners should review it for specific detection and remediation guidance, including updating to a patched version of the DukaPress plugin beyond 3.2.4 where available.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of untrusted input parameters before use, which would have blocked the unsanitized reflected XSS payload in the DukaPress plugin.
Requires filtering or encoding of information prior to output, directly mitigating the failure to escape the parameter that enables reflected XSS execution.
Provides mechanisms to detect and block malicious code/scripts delivered via web requests, offering secondary protection against the crafted malicious URL used in this reflected XSS attack.
