CVE-2025-25079: Medium Vulnerability in Garrett Grimm Simple Select All Text Box

CVE-2025-25079 is a medium-severity vulnerability affecting the Garrett Grimm Simple Select All Text Box plugin, specifically versions from n/a through 3.2. This vulnerability allows for improper neutralization of input during web page generation, resulting in a stored cross-site scripting (XSS) vulnerability. Attackers may leverage this vulnerability to execute arbitrary scripts in the context of the user's browser, potentially leading to data theft, session hijacking, or other malicious activities.

The CVSS score for this vulnerability is 6.5, indicating a medium level of severity. This score reflects the potential impact on confidentiality, integrity, and availability, which are all rated as low. Given the nature of the vulnerability and its potential impact, organizations should prioritize addressing this issue in their patching cycles.

Currently, there is no public exploit confirmed for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the risk to organizations includes the potential for attackers to exploit this vulnerability if left unpatched, emphasizing the need for vigilance and timely remediation.

Organizations should prioritize patching immediately, especially if they are using affected versions of the Simple Select All Text Box plugin. Ensuring that all software components are up to date will help mitigate the risk of exploitation and enhance overall security posture.

Vulnerability Details

The official description of CVE-2025-25079 states that it is an 'Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Garrett Grimm Simple Select All Text Box simple-select-all-text-box allows Stored XSS. This issue affects Simple Select All Text Box: from n/a through <= 3.2.' The vulnerability is classified under CWE-79.

The attack vector is classified as NETWORK, with a low attack complexity. The privileges required are low, and user interaction is required for the exploitation to succeed. The scope of the attack is considered changed, resulting in low impacts on confidentiality, integrity, and availability.

Technical Analysis

The root cause of this vulnerability lies in the improper handling of user input within the Simple Select All Text Box plugin. This lack of adequate sanitization allows attackers to inject malicious scripts that are subsequently stored and executed in the context of the user's session. This vulnerability can be exploited through a variety of attack vectors, primarily involving the manipulation of input fields that are not properly validated.

Given the low attack complexity and the requirement for user interaction, attackers may craft phishing messages or other social engineering techniques to lure users into triggering the exploit. The consequences of successful exploitation may include unauthorized access to sensitive user data, which can lead to severe reputational damage and potential legal liabilities.

Risk & Impact Analysis

The real-world risk associated with CVE-2025-25079 is significant due to the potential for stored XSS attacks. Organizations utilizing the vulnerable Simple Select All Text Box plugin risk exposing their users to crafted malicious content that can hijack sessions, steal cookies, or redirect users to harmful sites. The blast radius of this vulnerability is broad, as it can affect any user of the plugin without requiring deep system access.

Organizations should assess the urgency based on the CVSS score and the potential impacts of exploitation. With a score of 6.5, this vulnerability should be addressed in the priority patch cycle, particularly for those who maintain user-facing applications that utilize this plugin.

Exploitation Status

Affected Versions
