Threat actors began probing internet-exposed PraisonAI instances within 3 hours and 44 minutes of public disclosure of CVE-2026-44338, a missing-authentication flaw in the product’s legacy Flask API server. The vulnerability, tracked in GitHub advisory GHSA-6rmh-7xcm-cpxj, affects versions 2.5.6 through 4.6.33 and was fixed in 4.6.34. Sysdig said the issue stems from authentication being disabled by default in the legacy api_server.py, allowing unauthenticated access to protected endpoints including GET /agents and POST /chat.
Sysdig observed scanning from 146.190.133[.]49 using the User-Agent CVE-Detector/1.0, with activity focused on validating exploitability rather than full hands-on abuse, as no POST /chat requests were seen. Even so, exposed deployments could allow attackers to view agent configurations, trigger workflows defined in agents.yaml, exhaust model or API quotas, expose data, or execute downstream actions through connected tools. Defenders were urged to upgrade to PraisonAI 4.6.34 or later, retire the legacy API server, restrict exposure of port 8080, monitor for unauthenticated requests to /agents and /chat, and review credentials and billing tied to configured agents.

4 events from the most recent confirmed update back to the earliest known activity.
On 2026-05-12, Sysdig published research documenting the near-immediate scanning for CVE-2026-44338 and warning that exposed workflows could enable quota exhaustion, tool execution, data exposure, and downstream abuse. The company recommended upgrading to 4.6.34 or later, restricting exposure of port 8080, and monitoring for unauthenticated GET /agents and POST /chat requests.
Sysdig observed probing of internet-exposed PraisonAI instances 3 hours and 44 minutes after the public advisory, including requests from 146.190.133.49 using the User-Agent "CVE-Detector/1.0." The activity appeared aimed at validating exploitability of the vulnerable endpoint rather than fully weaponizing the flaw.
PraisonAI addressed the authentication bypass vulnerability in release 4.6.34. The fix remediated the legacy API server issue that had shipped with authentication disabled by default.
On 2026-05-11, GitHub published advisory GHSA-6rmh-7xcm-cpxj for CVE-2026-44338, a missing-authentication flaw in PraisonAI's legacy Flask API server. The issue affects versions 2.5.6 through 4.6.33 and can expose protected endpoints such as /agents and /chat to unauthenticated access.

PraisonAI, a multi-agent teams platform, disclosed two high-severity vulnerabilities affecting versions before **4.5.97** and **4.5.90**. The more severe issue, tracked as `CVE-2026-34953`, stems from `OAuthManager.validate_token()` returning `True` for tokens missing from its internal store, which is empty by default. That logic flaw lets attackers present arbitrary Bearer tokens to authenticate to the MCP server and gain full access to registered tools and agent capabilities. The vulnerability was classified as **CWE-863** with a CVSS v3.1 vector of `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N`. A second flaw, `CVE-2026-34934`, exposed PraisonAI to second-order SQL injection through `get_all_user_threads`. In affected versions before **4.5.90**, the function constructed raw SQL queries with Python f-strings using unescaped thread IDs previously stored in the database, allowing an attacker to plant a malicious thread ID via `update_thread` and trigger injection when thread lists were loaded. The bug could lead to full database compromise and was classified as **CWE-89** with a CVSS v3.1 vector of `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`; both issues were addressed in patched releases published through GitHub Security Advisories.

PraisonAI versions before **4.6.78** are affected by **CVE-2026-61435**, an authentication bypass in the Call API agent invocation functionality. The flaw appears when `PRAISONAI_CALL_AUTH=disabled` is configured: the application tries to restrict unauthenticated access to localhost, but determines the request origin from the client-controlled HTTP `Host` header via `request.url.hostname`, allowing an attacker to spoof `127.0.0.1` and appear local. A remote unauthenticated attacker who can reach the service can exploit the issue to access agent-related endpoints without logging in, including `GET /api/v1/agents` to enumerate registered agents and `POST /api/v1/agents/{agent_id}/invoke` to invoke them. The vulnerable logic is reported in `src/praisonai/praisonai/api/agent_invoke.py`; the issue is classified as **CWE-287** and carries a **CVSS v3.1** score vector of `AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N`, indicating low-complexity network exploitation with high integrity impact.

A critical remote code execution flaw, **`CVE-2026-61447`**, was disclosed in the PraisonAI AI agent framework, affecting versions before **`1.6.78`**. The vulnerability lies in **`CodeAgent._execute_python()`**, which executes LLM-generated Python without AST validation, import restrictions, or sandbox enforcement, allowing attackers to use prompt injection to make the agent run arbitrary code on the host. The issue received the maximum severity rating of **CVSS 10.0** under both v3.1 and v4.0. Successful exploitation can result in full host compromise and theft of sensitive data, including API keys, cloud credentials, database passwords, and other environment secrets, with potential pivoting into connected services. PraisonAI **`1.6.78`** fixes the issue, and defenders are being urged to upgrade immediately, reduce network exposure, rotate potentially exposed secrets, and monitor for anomalous outbound connections; no confirmed in-the-wild exploitation had been reported at disclosure time.
