CVE-2021-44150

CVE-2021-44150 is a high-severity vulnerability affecting tusdotnet versions through 2.5.0, where the client's reliance on SHA-1 for file content spoofing prevention is insufficient. This allows an unauthenticated attacker to achieve high integrity impact with low attack complexity over the network, as SHA-1 is cryptographically weak. While the CVSS score is 7.5, there is currently no evidence of active exploitation, public exploit code, or significant community discussion, suggesting a low immediate threat despite the inherent weakness.
