Missing network timeouts in the Linux builds of Progressive Robot hMailServer 6.3.0 through 6.3.5 allow a remote attacker to hold server threads indefinitely and so stop outbound mail delivery (denial of service). The server set its socket timeouts in the form Windows takes, which Linux refuses, and its HTTPS clients read without a deadline, so a peer that accepts a connection and then sends nothing held the waiting thread for as long as the connection stayed open. The MTA-STS policy fetch, enabled by default, is made during outbound delivery to mta-sts.<recipient domain>, so anyone who can make the server deliver mail to a domain they control - for example as the envelope sender of a message that bounces - can hold delivery threads until outbound delivery stops. The same flaw affects the DANE TLSA query, the OAuth2 token request, the ACME client, and the ManageSieve and metrics listeners, which a silent client stops from serving anyone else. Windows builds are not affected.

CVE-2026-81520 is a vulnerability in the MongoDB BI Connector where an unauthenticated network client can indefinitely hold an authentication session open by starting but not completing a SASL login exchange. This lack of timeout or read deadline allows the session to retain resources such as a worker, client connection slot, and backend database connections until the process is restarted. Repeated exploitation can exhaust connection capacity, blocking legitimate users from establishing new sessions.

CVE-2025-4656 is a low-severity vulnerability in HashiCorp Vault affecting rekey and recovery key operations. It involves synchronous access of a remote resource without a timeout, which can lead to denial of service caused by uncontrolled cancellation by a Vault operator. The vulnerability has been fixed in Vault Community Edition 1.20.0 and several Enterprise versions.

In version 3.23.0 of aimhubio/aim, certain methods that request data from external servers do not have set timeouts, causing the server to wait indefinitely for a response. This can lead to a denial of service, as the tracking server does not respond to other requests while waiting. The issue arises in the client used by the `aim` tracking server to communicate with external resources, specifically in the `_run_read_instructions` method and similar calls without timeouts.
