AI-suggested
Until a fix is available, organizations should consider mitigating the risk by configuring web servers or proxies to include the X-Content-Type-Options header with the value 'nosniff' to prevent MIME type sniffing.
Description
IBM Db2 Genius Hub versions 1.1.2 through 1.1.5 have a security vulnerability where the absence of the X-Content-Type-Options header allows MIME type sniffing. This can enable a remote authenticated attacker to bypass security restrictions. The vulnerability is classified under CWE-693 (Protection Mechanism Failure) and has a medium severity rating with a CVSS score of 5.4.
