CVE-2026-77970 ash-project CVE debrief

Who should care

Developers and administrators using ash_paper_trail, especially those handling sensitive data, should be aware of this vulnerability and take steps to mitigate it. This includes reviewing their version resources and embedded sensitive data, and applying vendor remediation when available. Organizations should inventory and assess version resources for potential sensitive data exposure and implement compensating controls to monitor and protect sensitive information. Security teams should prioritize patching or mitigating this vulnerability to prevent potential data breaches. Additionally, operators and platform administrators should be aware of the potential impact on their systems and take appropriate measures to secure sensitive data. Vulnerability management teams should also review and update their processes to address this type of vulnerability in the future. Those responsible for asset inventory and change management should verify that affected systems are identified and remediated. Monitoring and incident response teams should be prepared to detect and respond to potential exploitation of this vulnerability. Overall, a coordinated effort across development, operations, and security teams is necessary to address this vulnerability effectively. The CVE-2026-77970 issue highlights the importance of secure storage and handling of sensitive information in versioning and change tracking mechanisms. By taking proactive steps, organizations can minimize the risk associated with this vulnerability and protect their sensitive data. It is essential to stay informed about the vulnerability status of ash_paper_trail and apply patches or workarounds as soon as they become available. Regular security audits and risk assessments can also help identify and mitigate potential vulnerabilities before they are exploited. In summary, a broad range of stakeholders, including developers, administrators, security professionals, and operators, should be aware of this vulnerability and take appropriate actions to mitigate its impact. Effective communication and collaboration among these groups are crucial to ensuring the secure use of ash_paper_trail and protecting sensitive data. By

Technical summary

The ash_paper_trail library, specifically versions between 0.3.0 and before 0.7.0, contains a Cleartext Storage of Sensitive Information vulnerability. This issue arises because the :redact and :ignore actions in ash_paper_trail only protect top-level attributes of the tracked resource, leaving sensitive data in embedded resources, unions, or lists exposed in cleartext within version resources. The vulnerability affects ash_paper_trail versions from 0.3.0 up to but not including 0.7.0. This means that any application using ash_paper_trail within this version range may have sensitive information stored in cleartext, potentially exposing it to unauthorized access.

Defensive priority

Organizations using ash_paper_trail should review their version resources and embedded sensitive data, and apply vendor remediation when available.

Recommended defensive actions

• Review and update ash_paper_trail to version 0.7.0 or later
• Inventory and assess version resources for potential sensitive data exposure
• Implement compensating controls to monitor and protect sensitive information
• Consider temporarily disabling or restricting access to affected version resources
• Perform a thorough review of asset inventory to identify potentially affected systems
• Establish a rollback plan for affected systems in case of issues with the patch
• Monitor for suspicious activity related to version resources and sensitive data

Evidence notes

The CVE-2026-77970 issue arises from ash_paper_trail's handling of sensitive attributes in version resources. The :redact and :ignore actions only apply to top-level attributes of the tracked resource, not to embedded resources, unions, or lists. Consequently, sensitive data within these nested structures is stored in cleartext. For instance, if an action argument or non-sensitive attribute contains an embedded resource with a sensitive field, that field is written to the version table without encryption. This vulnerability affects ash_paper_trail versions from 0.3.0 up to but not including 0.7.0.
