If an attacker can control the content of the YAML configuration file passed to the --run_config parameter, arbitrary code can be executed during deserialization. This can lead to full system compromise. The vulnerability is triggered when a malicious YAML file is loaded, allowing the execution of arbitrary Python commands such as os.system(). It is recommended to upgrade PyYAML to version 5.4 or higher, and to use yaml.safe_load() to mitigate the issue.","cwes":[],"vendors":[{"vendor":"cloudflare","status":"blocks","basis":"claimed","firstOn":"2025-08-18","firstIsNew":true,"daysToRule":17,"daysAtMost":null,"freePlan":false,"claims":[{"id":"d37401431cc1bf37e1285516713f017854b56faa9ea1f87bb78f9c38b8bd933a","cve_id":"CVE-2025-50460","vendor":"cloudflare","product":"Cloudflare Managed Ruleset","rule_id":"69f4f161dec04aca8a73a3231e6fefdb","rule_name":"Ms-Swift Project - Remote Code Execution - CVE:CVE-2025-50460","change":"new","default_action":"Block","published_on":"2025-08-18","source_url":"https://developers.cloudflare.com/changelog/post/2025-08-18-waf-release/","source_title":"WAF Release - 2025-08-18","excerpt":"Ms-Swift Project - Remote Code Execution - CVE:CVE-2025-50460.
