Deeper analysisAI
CVE-2025-67927 is an improper neutralization of input during web page generation vulnerability, enabling reflected cross-site scripting (XSS) as defined by CWE-79. It affects the Link Whisper Free WordPress plugin (slug: link-whisper) developed by Spencer Haws, impacting all versions from an unspecified initial release through 0.8.8. Published on 2026-01-08, the issue 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 high severity due to network accessibility, low attack complexity, and changed scope.
Unauthenticated attackers (PR:N) can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) by crafting a malicious URL containing an XSS payload. Exploitation requires user interaction (UI:R), such as a site administrator or authenticated user clicking a phishing link or visiting a tainted page, causing the payload to reflect and execute in the victim's browser. Successful attacks enable low-impact effects on confidentiality (e.g., limited data exposure like session tokens), integrity (e.g., minor script injection), and availability (e.g., brief denial via resource consumption), amplified by the changed scope (S:C) to affect the site's context.
The Patchstack advisory documents this vulnerability in the WordPress Link Whisper Free plugin 0.8.8 at https://patchstack.com/database/Wordpress/Plugin/link-whisper/vulnerability/wordpress-link-whisper-free-plugin-0-8-8-cross-site-scripting-xss-vulnerability?_s_id=cve, providing details for security practitioners to assess mitigation, such as plugin updates or input sanitization.
