CVE-2026-57116: PraisonAI: AgentOS remains unauthenticated after incomplete fix version and allows remote agent invocation
PraisonAI: AgentOS remains unauthenticated after incomplete fix version and allows remote agent invocation
CVSS 9.8 Critical
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- No confirmed exploitation. It is not in CISA’s KEV catalog. That can change quickly after a public write-up; re-check if you are affected.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
praisonai(PyPI) >= 4.2.1, <= 4.6.57, fixed in 4.6.59. Check your lockfile, including transitive dependencies.
What it is
From the GitHub advisory
AgentOS remains unauthenticated after GHSA-pm96 patched version and allows remote agent invocation
Summary
PraisonAI's AgentOS FastAPI deployment surface remains unauthenticated in current main and in releases after the published patched version for GHSA-pm96-6xpr-978x / CVE-2026-40151.
The public AgentOS advisory is published as an instruction-disclosure issue with affected versions
This is broader than passive metadata disclosure. In any deployment where AgentOS wraps agents with tools, private context, memory, API integrations, or cost-bearing model calls, an unauthenticated reachable client can drive those agents.
Weakness type: CWE-200, CWE-306, CWE-862.
