CVE-2023-47204
CWE-502Published: November 2, 2023· Updated: Jun 17, 2026
Official Description
Unsafe YAML deserialization in yaml.Loader in transmute-core before 1.13.5 allows attackers to execute arbitrary Python code.
Risk Analysis
Transmute-core before version 1.13.5 is vulnerable to unsafe YAML deserialization, which allows remote attackers to execute arbitrary Python code. This critical vulnerability is highly dangerous as it can lead to full system compromise.
No public exploit is known, and the vulnerability is not in the KEV catalog. It is remotely exploitable with low attack complexity.
Upgrade to transmute-core version 1.13.5 or later to resolve the unsafe deserialization issue.
Technical Analysis
CVE-2023-47204 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
