With a CVSS score of 9.8 (Critical) and an EPSS score indicating high exploitability, this vulnerability poses a significant risk due to its network-based attack vector and low attack complexity, leading to full compromise of confidentiality, integrity, and availability. Exploit code is publicly available, including a Metasploit module, though there is no evidence of active exploitation in the wild or significant community discussion.
