CVE-2026-22906 is a critical vulnerability that allows user credentials to be stored using AES‑ECB encryption with a hardcoded key. An unauthenticated remote attacker who is able to obtain the configuration file can decrypt and recover plaintext usernames and passwords. This issue is exacerbated when combined with an authentication bypass, significantly increasing the risk of unauthorized access.
The severity of this vulnerability is classified as critical, with a CVSS score of 9.8. This score reflects the high impact on confidentiality, integrity, and availability. Organizations must prioritize patching immediately to mitigate the associated risks.
The exploitation status of this vulnerability is currently listed as awaiting analysis. However, the potential for exploitation remains high due to the nature of the vulnerability and the ease of access for attackers, making it imperative for organizations to understand and address this security flaw.
Risk to organizations includes unauthorized access to sensitive information, which can lead to further attacks and data breaches. Given the critical nature of this vulnerability, it is essential for security teams to act promptly.
Organizations should assess their systems for this vulnerability and implement necessary mitigations as soon as possible.
Vulnerability Details
The official description states that user credentials are stored using AES‑ECB encryption with a hardcoded key. The vulnerability is classified under CWE-321, which pertains to the use of hard-coded cryptographic keys. The CVSS score of 9.8 indicates a critical severity level, highlighting the potential for significant impacts on confidentiality, integrity, and availability.
The vulnerability affects an unspecified product from an unspecified vendor, and it was published on February 9, 2026. This lack of specific product details necessitates that all organizations review their systems for the potential presence of this vulnerability.
Technical Analysis
The root cause of the vulnerability stems from the improper storage of user credentials. The use of AES‑ECB encryption with a hardcoded key is a significant security flaw, as it does not provide adequate protection against decryption. Attackers can exploit this weakness by obtaining the configuration file, allowing them to access sensitive user data.
The attack vector is network-based, with low complexity and no privileges required, making it highly accessible for potential attackers. There is no user interaction required, further simplifying the exploitation process.
The impact on confidentiality, integrity, and availability is high, as attackers may gain unauthorized access to sensitive user information, leading to further security incidents. Organizations must be vigilant in monitoring for any exploitation attempts related to this vulnerability.
Risk & Impact Analysis
The deployment risk associated with CVE-2026-22906 is significant due to the critical nature of the vulnerability. Organizations are at risk of unauthorized access to sensitive information, which can lead to data breaches and loss of trust among customers. The blast radius potential is extensive, as the exploitation of this vulnerability could affect numerous users and systems.
Given the CVSS score of 9.8, organizations should prioritize remediation efforts immediately. The longer this vulnerability remains unaddressed, the greater the likelihood of exploitation, making it imperative to act swiftly.
