# CVE-2026-39305: PraisonAI Vulnerable to Arbitrary File Write / Path Traversal in Action Orchestrator

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.4% , percentile 36: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 36% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
- Only applies if your dependency tree includes PraisonAI (PyPI) <= 4.5.112, fixed in 4.5.113 . Check your lockfile, including transitive dependencies.

## What it is

PraisonAI is a multi-agent teams system. Prior to 1.5.113, the Action Orchestrator feature contains a Path Traversal vulnerability that allows an attacker (or compromised agent) to write to arbitrary files outside of the configured workspace directory. By supplying relative path segments (../) in the target path, malicious actions can overwrite sensitive system files or drop executable payloads on the host. This vulnerability is fixed in 1.5.113.

## Affected packages

- PyPI `PraisonAI` <= 4.5.112 → fixed: 4.5.113

## Affected products (CVE record)

- MervinPraison PraisonAI: < 4.5.113

## Severity

- GitHub_M CVSS 3.1: 9 `CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H`
- GitHub CVSS 3.1: 9.0 `CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.43% probability of exploitation activity in the next 30 days; percentile 36.
