CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:HSummary
CVE-2026-39305 is a critical-severity Path Traversal (CWE-22) vulnerability in Praison Praisonai. Its CVSS base score is 9.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-39305 is a Path Traversal vulnerability (CWE-22) in the Action Orchestrator feature of PraisonAI, a multi-agent teams system, affecting versions prior to 1.5.113. Published on 2026-04-07, it enables writing to arbitrary files outside the configured workspace directory by supplying relative path segments such as ../ in the target path. The issue carries a CVSS v3.1 base score of 9.0 (AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H).
Local attackers or compromised agents can exploit this vulnerability with low complexity and no privileges or user interaction required. Exploitation allows overwriting sensitive system files or dropping executable payloads on the host, leading to high impacts on integrity and availability due to the changed scope.
The vulnerability is fixed in PraisonAI version 1.5.113. Additional details are available in the GitHub security advisory at https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-jfxc-v5g9-38xr.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes special path elements before pathname construction occurs.
Least privilege reduces the impact of any unauthorized file access obtained via traversal.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
