Security Summary

CVE-2025-23874 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the WP Block Pack plugin (wp-block-pack) developed by FalconTheme Team.

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), indicating network accessibility, low attack complexity, no privileges required, and user interaction needed, with a changed scope leading to low impacts on confidentiality, integrity, and availability. Remote attackers can exploit it by crafting malicious input that reflects unsanitized on a web page, tricking authenticated or unauthenticated users into interacting with it, such as via a phishing link, to execute arbitrary scripts in the victim's browser context.
