AV:L because exploitation requires controlling local deployment config; PR:L since supplying the config/agents file needs some privilege; full C/I/A impact from arbitrary Python execution in the server process.

DescriptionCVE.org

PraisonAI before 4.6.78 fails to safely encode deployment configuration values when generating Python source code for API servers. Attackers can inject arbitrary Python expressions through the deploy.api.host and agents_file configuration parameters that execute when the generated server starts or handles requests.

AnalysisAI

Code injection in PraisonAI before 4.6.78 lets attackers who control deployment configuration achieve arbitrary Python execution because the API-server deployment generator fails to safely encode the deploy.api.host and agents_file values before emitting them into generated Python source (CWE-94). Injected expressions run when the generated API server starts or handles requests, yielding full code execution in the server process. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to control the value of the deploy.api.host and/or agents_file deployment configuration parameters that feed PraisonAI's API-server code generator; the injected Python only runs after the generated server is started or serves a request (the UI:P / operator-action element). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Signals are mixed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario In a shared or multi-tenant PraisonAI setup, an attacker who can edit the deployment configuration sets deploy.api.host (or the agents_file value) to a crafted Python expression rather than a hostname. When an operator runs the deployment generator and the produced API server module is started or handles its first request, the embedded expression executes with the server's privileges. …
Remediation Upgrade to PraisonAI 4.6.78 or later, which is the first release incorporating the fix; the change is in commit 1620b49f36945d8cc8ee5635b906c960df5097a0 and described in advisory GHSA-79fv-7hq9-w7xg (https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-79fv-7hq9-w7xg). … Detailed patch versions, workarounds, and compensating controls in full report.
