❌ PyYAML-3.12.tar.gz (Vulnerable Library)
Vulnerability Details
A vulnerability was discovered in the PyYAML library in all versions, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. .load() defaults to using FullLoader and FullLoader is still vulnerable to RCE when run on untrusted input. Applications that use the library to process untrusted input may be vulnerable to this flaw. An attacker could use this flaw to execute arbitrary code on the system by abusing the python/object/new constructor.
The fix for CVE-2020-1747 was not enough to fix this issue.
