CVE-2025-11263: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in linkwhspr Link Whisper Free
The Link Whisper Free plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the type parameter in all versions up to, and including, 0.8.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
AI Analysis
Technical Summary
CVE-2025-11263 is a reflected cross-site scripting vulnerability in the Link Whisper Free WordPress plugin (up to version 0.8.8). The issue stems from improper neutralization of input in the 'type' parameter, enabling unauthenticated attackers to inject malicious scripts that execute when a user clicks a crafted link. This vulnerability can lead to partial confidentiality and integrity impacts but does not affect availability. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary scripts in the context of the victim's browser session when the victim interacts with a malicious link. This can lead to partial disclosure of information and modification of data accessible to the user. There is no impact on system availability. The vulnerability affects confidentiality and integrity to a limited extent.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted links involving the Link Whisper Free plugin and consider disabling or removing the plugin if possible. Monitor vendor channels for updates regarding patches or official mitigations.
