CVE-2026-40288
CriticalSummary
PraisonAI to system wieloagentowy, który w wersjach poniżej 4.5.139 oraz 1.5.140 jest podatny na wykonanie dowolnych poleceń i kodu poprzez nieufne pliki YAML. Silnik workflow nie weryfikuje ani nie izoluje plików YAML, co pozwala na wykonanie poleceń powłoki, skryptów inline w Pythonie oraz dowolnych skryptów Pythona.
Risk Assessment
Atakujący, który ma możliwość dostarczenia lub wpływania na plik YAML workflow, może uzyskać pełny dostęp do systemu, co prowadzi do kompromitacji maszyny oraz wszelkich dostępnych danych lub poświadczeń. To stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację PraisonAI do wersji 4.5.139 lub nowszej oraz 1.5.140 lub nowszej dla praisonaiagents. Należy również wprowadzić odpowiednie mechanizmy weryfikacji i izolacji plików YAML w środowiskach CI oraz w repozytoriach współdzielonych.

A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
PraisonAI is a multi-agent teams system. In versions below 4.5.139 of PraisonAI and 1.5.140 of praisonaiagents, the workflow engine is vulnerable to arbitrary command and code execution through untrusted YAML files. When praisonai workflow run <file.yaml> loads a YAML file with type: job, the JobWorkflowExecutor in job_workflow.py processes steps that support run: (shell commands via subprocess.run()), script: (inline Python via exec()), and python: (arbitrary Python script execution)—all without any validation, sandboxing, or user confirmation. The affected code paths include action_run() in workflow.py and _exec_shell(), _exec_inline_python(), and _exec_python_script() in job_workflow.py. An attacker who can supply or influence a workflow YAML file (particularly in CI pipelines, shared repositories, or multi-tenant deployment environments) can achieve full arbitrary command execution on the host system, compromising the machine and any accessible data or credentials.
