What is CVE-2026-64773?

An attacker with access to a container's exposed TCP port may exploit a flaw that allows for an unbounded accumulation of data in the host's memory during backend container interactions. This may lead to excessive memory usage without limits and extended wait times for data processing, posing risks to system stability and performance. To mitigate this risk, users should upgrade to Container version 1.2.0 or later.
