VCID-2wh2-rac2-53ax
Aliases: CVE-2020-14343 GHSA-8q59-q68h-6hv4 PYSEC-2021-142 |
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. |
Affected by 0 other vulnerabilities. |

VCID-5y6u-xqht-n3ft
Aliases: PYSEC-2020-195 |
PyYAML 5.1 through 5.1.2 has insufficient restrictions on the load and load_all functions because of a class deserialization issue, e.g., Popen is a class in the subprocess module. NOTE: this issue exists because of an incomplete fix for CVE-2017-18342. |
Affected by 3 other vulnerabilities. |

| VCID-1d4s-2baq-wuhk | In PyYAML before 5.1, the yaml.load() API could execute arbitrary code if used with untrusted data. The load() function has been deprecated in version 5.1 and the 'UnsafeLoader' has been introduced for backward compatibility with the function. |
