Summary
This Pull Request proposes correcting the Attack Complexity rating for CVE-2023-26031 / GHSA-94jh-j374-9r3j to align with the CVSS v4 specification. Currently rated as Attack Complexity = Low, this assignment does not accurately reflect the conditions necessary for successful exploitation—particularly in remote scenarios, which lead to Attack Complexity = High.
Rationale
Below is the detailed rationale for updating the rating to Attack Complexity = High:
The vulnerability under discussion requires an attacker to possess target-specific login credentials to authenticate with the YARN cluster in remote exploitation scenarios according to the description excerpts:
This requirement aligns with the CVSS v4 definition of Attack Complexity = High, which states:
In this case, obtaining valid login credentials constitutes an example of such a target-specific secret, as it requires additional steps beyond typical reconnaissance methods. These credentials are essential to initiating the attack and introduce significant barriers, increasing the complexity of the exploit.
