CVE-2025-22766 identifies a critical vulnerability in the Zarinpal Paid Download plugin developed by Masoud Amini. This high-severity vulnerability allows for reflected cross-site scripting (XSS), which poses significant risks to organizations utilizing this plugin. With a CVSS score of 7.1, the issue highlights an urgent need for remediation efforts to prevent potential exploitation.
Organizations using the affected versions of Zarinpal Paid Download, specifically versions from n/a up to and including 2.3, are at risk. The vulnerability remains in a deferred status, yet the potential for exploitation underscores the importance of addressing this vulnerability promptly. Risk to organizations includes unauthorized data access and manipulation.
Currently, there are no known exploits for this vulnerability, which is a relief, but it does not negate the necessity for immediate action. Organizations should prioritize patching as part of their vulnerability management program to mitigate any future risks.
Urgency for defenders is high; organizations must address this vulnerability in their upcoming patch cycles to safeguard against potential attacks that exploit reflected XSS vulnerabilities.
Vulnerability Details
The vulnerability is classified as an improper neutralization of input during web page generation ('Cross-site Scripting'). It allows attackers to execute arbitrary scripts in the context of the user’s browser, which could lead to data theft or manipulation. The CVSS vector indicates that this vulnerability has a low attack complexity and does not require any privileges for successful exploitation, although user interaction is needed.
This vulnerability affects the Zarinpal Paid Download plugin across all versions not patched or those specifically identified as version 2.3 and below. The CVSS base score of 7.1 denotes this vulnerability as high severity, emphasizing its potential impact on confidentiality, integrity, and availability.
The vulnerability was published on January 15, 2025, and is classified under CWE-79, which concerns improper neutralization of input. Organizations must remain vigilant and conduct regular security assessments to identify and mitigate risks associated with such vulnerabilities.
Technical Analysis
The root cause of CVE-2025-22766 lies in the improper handling of user input during the generation of web pages, allowing the injection of malicious scripts. Attackers can exploit this vulnerability through a network attack, as it requires user interaction to trigger the XSS payload. The low attack complexity means that a successful attack could occur with minimal effort.
Given that no privileges are required for exploitation, the vulnerability can be triggered by any user, increasing the risk exposure. User interaction is a prerequisite, as the attack typically involves a crafted URL that the user must click on, leading to the execution of the attacker's script in the victim's browser.
The impact on confidentiality, integrity, and availability is rated as low, indicating that while the potential exists for sensitive data exposure or manipulation, the overall effect on the system's functionality is limited. However, the implications of a successful XSS attack can lead to severe repercussions for organizations, including reputational damage and loss of user trust.
Risk & Impact Analysis
The real-world deployment risk for CVE-2025-22766 is significant, especially for organizations that rely on the Zarinpal Paid Download plugin for e-commerce or digital content distribution. The potential for reflected XSS could allow attackers to exploit unsuspecting users and execute arbitrary scripts that could compromise their data.
This vulnerability matters to organizations as it can lead to unauthorized access to sensitive information, manipulation of content, and a potential breach of customer trust. The blast radius is particularly concerning in environments where sensitive transactions occur, as the exploitation could cascade into larger security incidents.
Given the CVSS score of 7.1 and the fact that it is not currently included in the Known Exploited Vulnerabilities (KEV) database, organizations should still prioritize remediation efforts. The EPSS score of 0.00206 indicates a low likelihood of exploitation, but this should not be a reason to neglect the vulnerability, as the potential impact remains high.
