Published Sep 9, 2026CWE-502EPSS 0.72%

Overview

CVE-2026-87874 is a high-severity vulnerability. It was published on September 9, 2026 and has a CVSS 3.1 base score of 8.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
