Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-15 mandates information output filtering, directly addressing the improper neutralization of input during web page generation that enables reflected XSS in the ePermissions plugin.
SI-10 requires validation of information inputs, preventing malicious XSS payloads from being accepted and reflected unsanitized in the vulnerable WordPress plugin.
SI-2 ensures timely flaw remediation, such as patching the ePermissions plugin versions <=1.2 to eliminate the reflected XSS vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Reflected XSS vulnerability explicitly requires user interaction via clicking a malicious link to deliver and execute arbitrary JavaScript scripts in the victim's browser context.

Deeper analysisAI
CVE-2025-23635 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the ePermissions WordPress plugin developed by mobde3net. The issue affects ePermissions versions from n/a through 1.2 inclusive, allowing malicious input to be reflected without proper sanitization during web page generation.
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), the vulnerability can be exploited remotely over the network with low attack complexity and no required privileges, though it needs user interaction such as clicking a malicious link. Attackers can deliver reflected XSS payloads via crafted inputs, executing arbitrary scripts in the context of a victim's browser when accessing the affected site, potentially leading to low impacts on confidentiality, integrity, and availability, such as limited data exposure or site defacement.
