CVE-2025-26561 is a Stored Cross-site Scripting (XSS) vulnerability in Elfsight Yottie Lite, a popular WordPress plugin. This vulnerability allows attackers to inject malicious scripts into web pages viewed by users, potentially leading to unauthorized actions or data exposure. The issue affects versions of Elfsight Yottie Lite from n/a through version 1.3.3.
The vulnerability has a CVSS score of 5.9, classified as medium severity. This score indicates a moderate risk where exploitation is feasible but requires specific conditions to succeed. Given the nature of XSS vulnerabilities, organizations must take proactive measures to mitigate risks associated with this flaw.
Risk to organizations includes potential data theft, unauthorized actions performed on behalf of users, and damage to user trust. As such, organizations utilizing the affected plugin should prioritize addressing this vulnerability to maintain the integrity and security of their web applications.
Currently, there is no public exploit confirmed for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) database. However, the medium severity and the nature of the vulnerability necessitate that organizations remain vigilant and prepare to implement remediation measures.
Vulnerability Details
The official description states that this vulnerability allows for improper neutralization of input during web page generation, leading to Stored XSS. The affected product is Elfsight Yottie Lite, specifically versions from n/a through 1.3.3. The CVSS 3.1 score is 5.9, indicating medium severity, with an attack vector of NETWORK, low attack complexity, high privileges required, user interaction needed, and low impacts on confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user input by the Elfsight Yottie Lite plugin during web page generation. This lack of input sanitization allows attackers to store malicious scripts that can be executed when users access the affected web pages.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely, without needing physical access to the system. The attack complexity is low, making it easier for potential attackers to execute their malicious scripts.
High privileges are required to exploit this vulnerability, and user interaction is necessary, as the malicious script must be executed within the context of a user's session. The confidentiality, integrity, and availability impacts are low, suggesting that while the vulnerability is serious, it does not directly compromise sensitive data or disrupt services.
Risk & Impact Analysis
Organizations using Elfsight Yottie Lite should understand the real-world risks associated with this vulnerability. The potential for Stored XSS means that attackers can hijack user sessions, steal cookies, or perform actions on behalf of users without their consent. This could lead to significant trust issues from users and potential data breaches.
The urgency for remediation is moderate, given the medium severity and lack of active exploitation. Organizations should schedule remediation during their priority patch cycles to mitigate this vulnerability and protect their users.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
This vulnerability affects all versions of Elfsight Yottie Lite up to and including version 1.3.3. Organizations should ensure they are using a patched version to avoid potential exploitation.
Mitigation & Remediation
Organizations should prioritize patching Elfsight Yottie Lite to the latest version. If immediate patching is not feasible, consider implementing web application firewalls (WAFs) to filter out potential XSS payloads. Additionally, conducting regular security assessments, such as application security assessments can help identify and mitigate vulnerabilities like this.
Detection Guidance
Organizations should monitor logs for unusual behaviors indicative of XSS attacks, such as unexpected script execution or anomalous user actions. Implementing network signatures to detect such activity can also aid in early detection.
AppSecure Threat Intelligence Insight
