Improper Input Validation in PyYAML

CVE-2020-14343 / GHSA-8q59-q68h-6hv4

More information

Details

A vulnerability was discovered in the PyYAML library in versions before 5.4, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. This flaw allows an attacker to execute arbitrary code on the system by abusing the python/object/new constructor. This flaw is due to an incomplete fix for CVE-2020-1747.

PyYAML insecurely deserializes YAML strings leading to arbitrary code execution

CVE-2017-18342 / GHSA-rprw-h62v-c2w7

More information

Details

In PyYAML before 4.1, the yaml.load() API could execute arbitrary code. In other words, yaml.safe_load is not used.
