Memory disclosure and denial of service in MongoDB Server's server-side JavaScript engine allow an authenticated user with read privileges and JavaScript execution rights to read freed heap memory or crash the mongod process. The flaw is triggered during BSON-to-JavaScript array conversion when operators such as $where or $function are evaluated. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it was self-reported by MongoDB.

Information disclosure in MongoDB Server allows authenticated users holding the read role to obtain small amounts of uninitialized stack memory by submitting specially-crafted filemd5 commands. The flaw stems from CWE-457 (Use of Uninitialized Variable) in the filemd5 command handler, and while no public exploit has been identified at time of analysis, the low attack complexity and network reachability make it a credible insider/credential-theft risk against MongoDB databases.
