It published in pypi as \"tenable-jira-cloud\". In tenable-jira-cloud before version 1.1.21, it is possible to run arbitrary commands through the yaml.load() method. This could allow an attacker with local access to the host to run arbitrary code by running the application with a specially crafted YAML configuration file. This is fixed in version 1.1.21 by using yaml.safe_load() instead of yaml.load().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":8.6},"cwes":["CWE-502"],"references":["https://github.com/tenable/integration-jira-cloud/commit/f8c2095fd529e664e7fa25403a0a4a85bb3907d0","https://github.com/tenable/integration-jira-cloud/security/advisories/GHSA-8278-88vv-x98r","https://pypi.org/project/tenable-jira-cloud/","https://pyyaml.docsforge.com/master/documentation/#loading-yaml","https://github.com/tenable/integration-jira-cloud/commit/f8c2095fd529e664e7fa25403a0a4a85bb3907d0"],"products":["tenable:jira_cloud"],"source":"nvd","synced_at":"2026-10-19T21:15:50.279857260+00:00"},"epss":{"cve":"CVE-2021-21371","score":0.00452,"percentile":0.39286,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-8278-88vv-x98r","url":"https://osv.dev/vulnerability/GHSA-8278-88vv-x98r","summary":"Execution of untrusted code through config file","modified":"2026-09-10T03:49:26.585735497Z","packages":[{"ecosystem":"PyPI","name":"tenable-jira-cloud","purl":"pkg:pypi/tenable-jira-cloud","ranges":["<1.1.21"],"fixed":["1.1.21"]}]},{"id":"PYSEC-2021-60","url":"https://osv.dev/vulnerability/PYSEC-2021-60","summary":"","modified":"2023-11-08T04:04:43.605874Z","packages":[{"ecosystem":"PyPI","name":"tenable-jira-cloud","purl":"pkg:pypi/tenable-jira-cloud","ranges":["<1.1.22"],"fixed":["1.1.22"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
