Answer in brief
CVE-2026-87874 records a High severity (CVSS 8.1) vulnerability in Community.general: community.general: memcached cache plugin deserializes untrusted pickle data from memcached, enabling cache-poisoning remote code execution on the ansible controller. The current sources do not mark it as known exploited. The current feed maps Red Hat/ansible-collection-community-general (generic). Check affected ranges and fixed versions before updating.

A flaw was found in the memcached cache plugin of the community.general Ansible collection. Although its documentation states that records are stored in JSON format, the plugin performs no explicit serialization and relies on python-memcached, which pickles values on write and unpickles them on read. Because memcached is unauthenticated and cache keys are predictable, an attacker able to reach a network-exposed or shared memcached instance can write a crafted pickle payload that is deserialized and executed on the Ansible controller when the poisoned fact cache is next read, leading to remote code execution.
