CVE-2026-44338: PraisonAI ships and generates a legacy API server with authentication disabled by default, allowing unauthenticated workflow execution

Noroxi assessment

Priority: Monitor (action score 39/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 32.5% (FIRST EPSS); higher than 98.3% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: MervinPraison PraisonAI 4.6.34.

Low priority for now. Upgrade to MervinPraison PraisonAI 4.6.34 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

PraisonAI is a multi-agent teams system. From version 2.5.6 to before version 4.6.34, PraisonAI ships a legacy Flask API server with authentication disabled by default. When that server is used, any caller that can reach it can access /agents and trigger the configured agents.yaml workflow through /chat without providing a token. This issue has been patched in version 4.6.34.
