In Ubuntu, Subiquity version 24.04.4 could leak sensitive user credentials during crash reporting. Upon installation failure, if a user submitted a bug report to Launchpad, Subiquity could include certain user credentials, such as the user's plaintext Wi-Fi password, in the attached logs. This vulnerability is classified as low severity with a CVSS score of 2.7, indicating a low risk to organizations. However, the potential exposure of sensitive data necessitates prompt action.
Risk to organizations includes the unintended disclosure of user information, which could lead to unauthorized access to accounts or networks. Although the attack vector is network-based and the attack complexity is low, the lack of required privileges or user interaction indicates that this vulnerability could be exploited relatively easily.
Currently, there are no known public exploits for this vulnerability, and it has not been reported in the Known Exploited Vulnerabilities (KEV) catalog. Despite its low severity, organizations should prioritize patching immediately to mitigate any potential risks.
As this vulnerability has been analyzed and disclosed, it is crucial for organizations using Ubuntu Subiquity to be aware of the potential risks and to take proactive steps to secure their systems.
Vulnerability Details
The official description states that Subiquity could leak sensitive user credentials during crash reporting. The CVSS score of 2.7 indicates a low severity rating, which reflects the potential impact of this vulnerability on confidentiality. The affected product is Ubuntu Subiquity version 24.04.4, published on April 9, 2026.
Technical Analysis
The root cause of this vulnerability lies in the crash reporting mechanism of Subiquity. When an installation fails and a user submits a bug report to Launchpad, the logs generated can inadvertently contain sensitive information, including plaintext Wi-Fi passwords. The attack vector is network-based, and the complexity is low, meaning that no special conditions are required for exploitation. Importantly, no user interaction is required, and confidentiality is impacted while integrity and availability remain unaffected.
Risk & Impact Analysis
Organizations using Ubuntu Subiquity are at risk of exposing sensitive user credentials through crash reports. Although the CVSS score suggests a low severity, the potential for credential leakage poses a significant risk to user accounts and data integrity. As such, organizations should schedule remediation and implement necessary patches to prevent unauthorized access.
