The NotificationX plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'regenerate' and 'reset' REST API endpoints in all versions up to, and including, 3.1.11. This vulnerability allows authenticated attackers, with Contributor-level access and above, to reset analytics for any NotificationX campaign, regardless of ownership. This poses a significant risk to organizations using the plugin.
The CVSS score for this vulnerability is 4.3, classifying it as medium severity. Organizations should recognize that the lack of appropriate access controls can lead to unauthorized data manipulation, potentially impacting data integrity and analytics accuracy. As the vulnerability is currently marked as deferred, it highlights the need for immediate attention from security teams.
Risk to organizations includes the potential for data integrity issues, where unauthorized users can modify campaign analytics, leading to misleading performance metrics. Organizations should prioritize patching this vulnerability to prevent exploitation by malicious actors. The urgency for defenders is high, given that the attack vector is over the network with low complexity.
Organizations using the NotificationX plugin should assess their current configurations and user roles to mitigate risks associated with this vulnerability. It is crucial to implement proper access controls and review user permissions to prevent unauthorized actions.
Vulnerability Details
The NotificationX plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'regenerate' and 'reset' REST API endpoints in all versions up to, and including, 3.1.11. This vulnerability allows authenticated attackers, with Contributor-level access and above, to reset analytics for any NotificationX campaign, regardless of ownership.
The CVSS score for this vulnerability is 4.3, which indicates medium severity. The attack vector is NETWORK, and the attack complexity is low, meaning that the prerequisite for exploiting this vulnerability is minimal. Privileges required are low, and no user interaction is necessary for the attack.
The integrity impact is rated as low, which means that while unauthorized modifications can occur, they do not threaten system availability or confidentiality. The vulnerability is categorized under CWE-862, which pertains to lack of authorization.
Technical Analysis
The root cause of this vulnerability stems from insufficient capability checks on REST API endpoints, which allow authenticated users to perform actions that should be restricted based on their user role. The attack vector is through the network, indicating that no physical access is required to exploit this issue.
Attack complexity is low, meaning that attackers do not need advanced skills to exploit this vulnerability. Privileges required are low, as attackers only need Contributor-level access. User interaction is not required, allowing attackers to exploit the vulnerability without any additional steps from the user.
The vulnerability impacts integrity, as unauthorized users can modify analytics data, which can lead to inaccurate reporting and decision-making. However, there is no confidentiality impact, and the availability of the system remains unaffected.
Risk & Impact Analysis
Real-world deployment risk includes the possibility of malicious actors resetting analytics for campaigns, leading to confusion and potentially financial losses. Organizations using this plugin should be aware that the blast radius could affect multiple campaigns, especially if multiple users have Contributor-level access.
This vulnerability matters to organizations as it undermines the integrity of their analytics, which are crucial for making informed decisions. Organizations should assess their deployment to understand the potential impact and take steps to mitigate risks associated with this vulnerability.
Urgency assessment based on CVSS indicates that organizations should address this vulnerability in their priority patch cycle. As the vulnerability has a medium CVSS score, it should not be ignored, and timely remediation is essential.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of the NotificationX plugin for WordPress prior to 3.1.11 are affected by this vulnerability. Organizations should ensure they update to the latest version as a priority to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching immediately. It is recommended to update the NotificationX plugin to the latest version to eliminate the vulnerability. In cases where immediate patching is not possible, organizations should review their user roles and permissions to limit access for Contributor-level users.
Additionally, organizations can implement configuration hardening by ensuring that proper capability checks are in place for REST API endpoints. Regular audits of user access and permissions can further reduce the risk of unauthorized actions.
For further guidance on security practices, organizations may consider engaging in penetration testing to identify similar weaknesses.
Detection Guidance
Organizations should monitor logs for any unauthorized attempts to access the 'regenerate' and 'reset' REST API endpoints. Behavioral anomalies from authenticated users, especially those with Contributor-level access, should be flagged for further investigation.
Network signatures targeting these endpoints can also be implemented to detect potential exploitation attempts. Regular reviews of access permissions and user roles can help ensure that only authorized individuals have the necessary access.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability lies in its demonstration of the importance of robust access controls in plugins and applications. This incident highlights the necessity of continuous security assessments and the implementation of best practices to safeguard against unauthorized access.
Security teams must recognize patterns from vulnerabilities like CVE-2026-0554 to strengthen defenses. By understanding the attack vectors and potential impacts, organizations can prepare better to mitigate similar risks in the future.
Strategic defensive takeaways include adopting a proactive security posture, ensuring regular updates of plugins and software, and utilizing services such as application security assessments to identify and remediate vulnerabilities promptly.
