Detailsinfo

A vulnerability classified as critical was found in DataDog Agent up to 7.70.x. Affected by this vulnerability is an unknown part of the file opt/datadog-agent/python-scripts/__pycache__. The manipulation with an unknown input leads to a default permission vulnerability. The CWE definition for the vulnerability is CWE-276. During installation, installed file permissions are set to allow anyone to modify those files. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The Datadog Agent collects events and metrics from hosts and sends them to Datadog. A vulnerability within the Datadog Linux Host Agent versions 7.65.0 through 7.70.2 exists due to insufficient permissions being set on the `opt/datadog-agent/python-scripts/__pycache__` directory during installation. Code in this directory is only run by the Agent during Agent install/upgrades. This could allow an attacker with local access to modify files in this directory, which would then subsequently be run when the Agent is upgraded, resulting in local privilege escalation. This issue requires local access to the host and a valid low privilege account to be vulnerable. Note that this vulnerability only impacts the Linux Host Agent. Other variations of the Agent including the container, kubernetes, windows host and other agents are not impacted. Version 7.71.0 contains a patch for the issue.

The advisory is shared at github.com. This vulnerability is known as CVE-2025-61667 since 09/29/2025. The exploitation appears to be easy. An attack has to be approached locally. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1222 for this issue.

Upgrading to version 7.71.0 eliminates this vulnerability.
