CVE-2023-47640 is a high-severity vulnerability affecting DataHub, an open-source metadata platform. The vulnerability stems from the use of a weak SHA-1 HMAC with a short key length for signing session cookies, making them susceptible to brute-force attacks. An authenticated attacker could exploit this to crack the signing key and gain escalated privileges by forging privileged session cookies. With a CVSS score of 8.8 (High), the attack vector is network-based with low complexity, leading to high confidentiality, integrity, and availability impacts. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
