CVE-2025-25080 represents a medium-severity vulnerability classified as a Cross-Site Scripting (XSS) issue within the gubbigubbi Kona Gallery Block plugin, specifically affecting the kona-instagram-feed-for-gutenberg. The vulnerability allows for stored XSS, which can be particularly dangerous as it enables attackers to inject malicious scripts that can be executed in the context of a user’s session, potentially leading to unauthorized actions or data exposure.
This vulnerability is scored 6.5 on the CVSS scale, indicating medium severity. The implications for organizations using this plugin are significant, given that it could allow attackers to exploit the vulnerability through network access with low attack complexity and minimal privileges required. The urgency for defenders is high, as attackers may leverage this vulnerability to compromise user sessions.
Organizations should prioritize patching immediately, especially those utilizing the affected version of the Kona Gallery Block plugin, to mitigate the risks associated with this vulnerability. The details surrounding the exploitation status indicate that there are currently no known exploits, but vigilance is necessary.
Given the nature of XSS vulnerabilities, the potential for real-world exploitation exists, and organizations should remain alert for any signs of unauthorized access or exploitation attempts.
Vulnerability Details
The official CVE description states, "Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in gubbigubbi Kona Gallery Block kona-instagram-feed-for-gutenberg allows Stored XSS. This issue affects Kona Gallery Block: from n/a through <= 1.7." This vulnerability is categorized under CWE-79, which relates to improper neutralization of input during web page generation.
The CVSS score of 6.5 indicates a medium severity level, with an attack vector categorized as NETWORK, low attack complexity, and low privileges required. User interaction is necessary for the exploitation, but the potential impacts on confidentiality, integrity, and availability are also marked as low.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input, which allows for the injection of malicious scripts during the generation of web pages. Attackers can exploit this by sending crafted input that the server does not properly sanitize, leading to stored XSS.
The attack vector is primarily network-based, meaning that an attacker can exploit the vulnerability remotely. The complexity of the attack is low, making it accessible to a wide range of attackers. The level of privileges required is low, and user interaction is necessary to trigger the XSS payload. This vulnerability has low impacts on confidentiality, integrity, and availability.
Risk & Impact Analysis
The deployment risk associated with this vulnerability is significant, as organizations using the affected versions of the Kona Gallery Block may expose their users to malicious scripts. This can lead to unauthorized actions being performed on behalf of users, potentially compromising sensitive information or account integrity.
The blast radius for this vulnerability is potentially wide, as it can affect any user interacting with the compromised plugin. Organizations must understand the implications of such vulnerabilities, particularly in environments where user-generated content is prevalent.
The urgency assessment is high, given the CVSS score and the potential for exploitation, even though no known exploits currently exist. Organizations should ensure that they are proactive in addressing this vulnerability to prevent any potential exploitation.
