CVE-2025-26562 is a high-severity vulnerability identified in the Shambhu Patnaik RSS Filter plugin, specifically affecting versions from n/a up to 1.2. This vulnerability allows for Cross-Site Request Forgery (CSRF), which can subsequently exploit stored Cross-Site Scripting (XSS). The CVSS score for this vulnerability is 7.1, indicating a significant risk to affected systems.
The vulnerability's impact is classified as high due to its ability to allow attackers to perform actions on behalf of authenticated users without their consent. Given that this vulnerability remains deferred in status, it is crucial for organizations utilizing this plugin to assess their exposure and take necessary actions.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability, particularly as it involves user interaction to exploit. Understanding the attack vector, which is network-based, is essential for implementing effective defenses.
Defenders should remain vigilant, as the exploitation status indicates that no public exploits have been confirmed. However, the potential for malicious actors to develop such exploits is always a risk, which emphasizes the need for timely remediation.
Vulnerability Details
The official description states that this vulnerability allows for CSRF, enabling stored XSS in the Shambhu Patnaik RSS Filter plugin. The weakness is classified under CWE-352, indicating a direct relationship with CSRF vulnerabilities. Published on February 13, 2025, it has since been recognized for its potential impact on systems utilizing affected versions of the plugin.
Technical Analysis
The root cause stems from inadequate validation of user requests, allowing attackers to send unauthorized commands through CSRF. The attack vector is network-based, with a low complexity requirement for execution. Importantly, no privileges are needed to initiate the attack, although user interaction is required for successful exploitation.
The impacts of this vulnerability are categorized as low for confidentiality, integrity, and availability, but the ability to execute scripts in the context of a user session poses a significant risk of data theft or manipulation.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized actions performed by attackers on behalf of legitimate users, leading to data exposure or alteration. This vulnerability highlights the importance of implementing robust CSRF protections, especially in applications that handle sensitive user data.
The urgency for organizations is high, given the potential consequences of exploitation. Organizations should address this vulnerability in their priority patch cycle to reduce the risk of exploitation and safeguard user data.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
Affected product versions include all releases prior to version 1.2 of the RSS Filter. Organizations using these versions should take immediate steps to upgrade to the latest version to mitigate the risk.
Mitigation & Remediation
Organizations should implement the following mitigation strategies: ensure to apply the latest patches provided by the vendor, and consider enhancing CSRF token implementations to prevent unauthorized actions. Additionally, organizations may utilize penetration testing to validate the effectiveness of security measures and identify potential vulnerabilities in their applications.
Detection Guidance
Monitoring for unusual user behavior and tracking log indicators such as unexpected requests or user actions can aid in the detection of potential exploitation attempts. Behavioral anomalies and changes in user activity should be scrutinized as part of a comprehensive security strategy.
