Attackers can plant instructions in ingested content such as fetched web pages, so the agent calls start_async_task and runs commands with user privileges and environment secrets.","state":0,"publishedAt":"2026-10-20T00:46:10.763+00:00","modifiedAt":"2026-10-22T21:09:21.545+00:00","affected":[{"ecosystem":"https://pypi.org","name":"EvoScientist","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"EvoScientist\",\n                    \"product\": \"EvoScientist\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.1.0\",\n                            \"lessThan\": \"0.2.5\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:pypi/evoscientist\",\n                    \"collectionURL\": \"https://pypi.org\",\n                    \"repo\": \"https://github.com/EvoScientist/EvoScientist\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.lasso.security/vulnerability-database/cve-2026-77930","https://github.com/EvoScientist/EvoScientist/issues/387","https://github.com/EvoScientist/EvoScientist/commit/d249e320bd856a7d31d859cfbb2bf75bab6c8686","https://github.com/EvoScientist/EvoScientist/releases/tag/v0.2.5","https://github.com/EvoScientist/EvoScientist/blob/ac58caab7bdd1706f3fee55891f611cd175d05b0/EvoScientist/subagents/_factory.py#L116","https://www.vulncheck.com/advisories/evoscientist-0.1.0-before-0.2.5-human-approval-bypass-via-async-sub-agents"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77930","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77930","identifiers":["CVE-2026-77930"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
