CVE-2024-26362 is an HTML injection vulnerability identified in Enpass Password Manager Desktop Client version 6.9.2 for Windows and Linux platforms. This vulnerability arises from insufficient sanitization of user-supplied input within the note creation feature, allowing an attacker to embed arbitrary HTML code. When a crafted note is viewed or processed by the application, the injected HTML can execute within the context of the Enpass client, potentially enabling malicious actions such as stealing stored credentials, executing scripts, or manipulating the application's interface. The vulnerability is classified under CWE-94, indicating improper control of code injection. The CVSS v3.1 base score is 8.8, with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, meaning it is remotely exploitable over the network without privileges but requires user interaction (e.g., opening a malicious note). The scope remains unchanged, but the impact on confidentiality, integrity, and availability is high. No patches or exploit code are currently publicly available, but the risk remains significant due to the sensitive nature of password managers and the potential for credential compromise. The vulnerability was reserved in February 2024 and published in April 2024, indicating recent discovery and disclosure.

The impact of CVE-2024-26362 is substantial for organizations globally, especially those relying on Enpass Password Manager for secure credential storage. Successful exploitation can lead to unauthorized disclosure of sensitive passwords and secrets, undermining user trust and potentially enabling further attacks such as account takeovers or lateral movement within networks. The integrity of stored data can be compromised by injecting malicious content, and availability may be affected if the application crashes or behaves unpredictably due to injected code. Since password managers are critical security tools, their compromise can have cascading effects on organizational security posture. The requirement for user interaction limits automated exploitation but does not eliminate risk, as social engineering or phishing can induce users to open crafted notes. The lack of patches increases exposure time, and the cross-platform nature (Windows and Linux) broadens the affected user base. Organizations in sectors with high security requirements, such as finance, healthcare, and government, face heightened risks due to the sensitivity of stored credentials.

To mitigate CVE-2024-26362, organizations should first monitor Enpass official channels for patches or updates addressing this vulnerability and apply them promptly once available. Until a patch is released, users should avoid opening notes from untrusted or unknown sources within the Enpass client. Implement strict policies restricting the import or creation of notes containing HTML or script content. Employ endpoint security solutions capable of detecting anomalous behavior or script execution within applications. Conduct user awareness training to recognize and avoid social engineering attempts that could lead to opening malicious notes. Consider isolating password manager usage to dedicated, hardened environments with limited network access to reduce exploitation risk. Regularly back up password vaults securely to enable recovery in case of compromise. Additionally, organizations may evaluate alternative password management solutions with stronger input sanitization controls as a temporary measure. Finally, enable multi-factor authentication on accounts protected by Enpass to reduce the impact of credential theft.
