Description

This security bulletin contains information about 1 security vulnerability.


1) Inclusion of Functionality from Untrusted Control Sphere (CVE-ID: CVE-2025-27607)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to between 30 December 2024 and 4 March 2025 Python JSON Logger was vulnerable to RCE through a missing dependency. This occurred because msgspec-python313-pre was deleted by the owner leaving the name open to being claimed by a third party. If the package was claimed, it would allow them RCE on any Python JSON Logger user who installed the development dependencies on Python 3.13 (e.g. pip install python-json-logger[dev]). A remote attacker can trick the victim into opening a specially crafted data, trigger the vulnerability and execute arbitrary code on the target system.
