Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

SI-10 enforces validation of information inputs, directly preventing the improper neutralization of malicious payloads in the WP Event Aggregator plugin that enables reflected XSS.

SI-15 Information Output Filtering good match

prevent

SI-15 requires filtering of information outputs, mitigating the reflection of unsanitized user input into web pages during generation in the vulnerable plugin.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates identification and timely remediation of system flaws, such as patching the WP Event Aggregator plugin versions through 1.8.2 affected by this XSS vulnerability.

Deeper analysisAI

CVE-2025-24700 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the WP Event Aggregator WordPress plugin from Xylus Themes. This issue impacts all versions of the plugin from n/a through 1.8.2.

The vulnerability carries 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), meaning it is exploitable remotely over the network with low attack complexity, no required privileges, but necessitating user interaction such as clicking a malicious link. An unauthenticated attacker can craft a URL containing a malicious payload that the plugin reflects unsanitized into the web page, enabling arbitrary JavaScript execution in the context of the victim's browser and potentially leading to low-level impacts on confidentiality, integrity, and availability across a changed scope.
