Description Ganesh 2026-09-29 06:14:52 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

The client-side field level encryption support in the MongoDB Python Driver can treat a key management endpoint value ending in ".sock" as a local Unix domain socket path rather than a remote host. A user with write access to the encryption key metadata stored in the database can cause an application using the driver to open connections to local sockets on the application host. Data sent over these connections is limited to the start of a TLS handshake, so no chosen content is transmitted.
Comment 1 Ben Beasley 2026-09-29 06:52:53 UTC 
The python-pdfminer package contains only pymongo code derived from pymongo/saslprep.py, so it won’t be affected by flaws in key management for field level encryption.
