CVE-2025-23839 is a high-severity vulnerability classified as an improper neutralization of input during web page generation, specifically a Cross-site Scripting (XSS) vulnerability. This vulnerability allows stored XSS, which could potentially be exploited by attackers to craft malicious scripts that are stored and executed in the web application.
The CVSS score assigned to this vulnerability is 7.1, indicating a high level of risk. This score reflects the potential impact on confidentiality, integrity, and availability, which are all classified as low in this case. However, the presence of this vulnerability in a widely used plugin could have significant real-world consequences if exploited.
Organizations utilizing the Asif Shakeel Sticky Button plugin, specifically versions up to 1.0, should be particularly vigilant, as this vulnerability affects all versions up to and including this release. The urgency for defenders is high due to the nature of the vulnerability and its potential to be exploited in the wild.
Currently, there are no known exploits or proof of concept publicly available, but the risk to organizations includes potential data theft, session hijacking, or other malicious activities facilitated by the execution of arbitrary scripts.
Given the high severity of this vulnerability, organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability.
Vulnerability Details
The vulnerability described in CVE-2025-23839 is categorized under CWE-79, which indicates improper neutralization of input. Specifically, this vulnerability allows stored XSS within the Asif Shakeel Sticky Button plugin. Affected versions include all versions up to and including 1.0.
The CVSS score of 7.1 highlights the need for immediate attention, as it reflects a high-risk level for exploitation. The vulnerability was published on January 24, 2025, and has a potential impact on stored content due to its nature.
Technical Analysis
The root cause of this vulnerability stems from insufficient input validation, allowing attackers to inject malicious scripts into the input fields of the web application. This vulnerability can be exploited via a network attack vector, requiring low attack complexity and no privileges. User interaction is required, as the victim must trigger the stored script, but the risk remains significant.
The confidentiality, integrity, and availability impacts are all classified as low, yet the potential for exploitation in a real-world scenario could lead to serious consequences for affected organizations.
Risk & Impact Analysis
The deployment risk associated with CVE-2025-23839 is considerable, as it affects a popular WordPress plugin that could be utilized across numerous websites. If exploited, attackers may be able to execute scripts that could steal sensitive user data or manipulate web application behavior.
Organizations should understand that the blast radius for this vulnerability could extend beyond the immediate environment, potentially affecting user trust and leading to reputational damage.
Given the CVSS score and the active exploitation status, organizations should address this vulnerability in their priority patch cycle. The urgency to remediate is high, and failure to act could result in significant security incidents.
