HIGHPre-NVD 8.78.7
EchelonGraph scoreLOW confidence

This high-severity CVE scores 8.7 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 77% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

PraisonAI is a multi-agent teams system. Prior to version 4.6.40, the fix for GHSA-9mqq-jqxf-grvw / CVE-2026-44336 is incomplete. The original advisory description named four vulnerable handlers in mcp_server/adapters/cli_tools.py. Commit 68cc9427 ("fix(security): harden MCP rules path handling…") added a _resolve_rule_path() helper and applied it to rules.create, rules.show, and rules.delete. workflow.show was left unchanged. Two adjacent handlers in the same file have the same pattern, workflow.validate and deploy.validate. Neither was mentioned in the original advisory. Both remained unchanged. The original advisory also identified the dispatcher (server.py:281-298) as a root cause. It accepts unvalidated **kwargs from params["arguments"] with no enforcement against the tool's declared input_schema. That code is unchanged prior to version 4.6.40. A single unauthenticated MCP tools/call to praisonai.workflow.show returns the contents of any file the host user can read: /etc/passwd, ~/.ssh/id_rsa, ~/.aws/credentials, or any project .env. Version 4.6.40 contains an updated fix.
