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.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2021-02-10T00:40:45.000000Z"}, {"uuid": "9bfe10c7-ee24-43f7-a647-29526d09ac88", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2020-14343", "type": "published-proof-of-concept", "source": "https://t.me/CyberSecurityTechnologies/4338", "content": "#exploit\nExperimenting with the CVE-2020-14343 PyYAML vulnerability\nhttps://github.com/raul23/pyyaml-CVE-2020-14343", "creation_timestamp": "2021-09-20T11:03:01.000000Z"}, {"uuid": "5617d59d-08a3-4cd9-8e57-0199f9b3b558", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2020-14343", "type": "seen", "source": "https://t.me/STUFFuckthesystem/1167", "content": "\u26a0\ufe0f Graphql Exploitation \u26a0\ufe0f\n\nUnderstanding Graphql & Enumeration of Graphql Schema\n\nhttps://payatu.com/blog/manmeet/graphql-exploitation-part-1\n\nUnauthorized Execution of Queries\n\nhttps://payatu.com/blog/manmeet/graphql-exploitation-part-2\n\nInjection attacks and XSS attacks\n\nhttps://payatu.com/blog/manmeet/graphql-exploitation-part-3\n\nResource Exhaustion (DOS)\n\nhttps://payatu.com/blog/manmeet/graphql-exploitation-part-4\n\nOffensive security\n\n1.
