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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/EvoScientist/EvoScientist/blob/ac58caab7bdd1706f3fee55891f611cd175d05b0/EvoScientist/subagents/_factory.py#L116","tags":[]},{"url":"https://github.com/EvoScientist/EvoScientist/commit/d249e320bd856a7d31d859cfbb2bf75bab6c8686","tags":[]},{"url":"https://github.com/EvoScientist/EvoScientist/issues/387","tags":[]},{"url":"https://github.com/EvoScientist/EvoScientist/releases/tag/v0.2.5","tags":[]},{"url":"https://www.lasso.security/vulnerability-database/cve-2026-77930","tags":[]},{"url":"https://www.vulncheck.com/advisories/evoscientist-0.1.0-before-0.2.5-human-approval-bypass-via-async-sub-agents","tags":[]}],"exploitRefs":[{"url":"https://github.com/EvoScientist/EvoScientist/blob/ac58caab7bdd1706f3fee55891f611cd175d05b0/EvoScientist/subagents/_factory.py#L116","tags":[]},{"url":"https://github.com/EvoScientist/EvoScientist/commit/d249e320bd856a7d31d859cfbb2bf75bab6c8686","tags":[]},{"url":"https://github.com/EvoScientist/EvoScientist/issues/387","tags":[]},{"url":"https://github.com/EvoScientist/EvoScientist/releases/tag/v0.2.5","tags":[]}],"hasPoc":true,"ai":null}
