CVE-2024-47833·Python vulnerability

Taipy is an open-source Python library for easy, end-to-end application development for data scientists and machine learning engineers. In affected versions session cookies are served without Secure and HTTPOnly flags. This issue has been addressed in release version 4.0.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

How likely is exploitation

FIRST's Exploit Prediction Scoring System puts the probability of this CVE being exploited in the next 30 days at 0.25% — higher than 16% of all published CVEs. EPSS is an independent forecast of exploitation, not a severity rating: it says nothing about how much damage a successful attack does, which is what a CVSS score measures.

Affected versions

Until: 4.0.0

Fixed in: 4.0.0

How to fix this CVE

Upgrade Taipy to version 4.0.0 or later to remediate the insecure session cookie configuration. The vulnerability stems from session cookies being transmitted without the Secure and HTTPOnly flags, which could allow attackers to intercept or manipulate session data over unencrypted connections or via client-side script injection. Ensure all instances of the Taipy library are updated across your development and production environments.

pip install --upgrade taipy>=4.0.0

Defensia detects this vulnerability

How to check if you are affected

  1. Check the installed Taipy version: pip show taipy | grep Version
  2. Verify if Taipy is used in your application: grep -r "import taipy" /path/to/app --include='*.py'
  3. Inspect session cookie headers in HTTP responses: curl -I https://your-taipy-app.com 2>&1 | grep -i 'set-cookie' and confirm absence of 'Secure' and 'HttpOnly' flags
  4. After upgrading, re-check session cookies: pip show taipy should display version 4.0.0 or higher, and Set-Cookie headers should now include 'Secure; HttpOnly' flags

FAQ

What is CVE-2024-47833?

This vulnerability affects Taipy, a Python library for data science applications, where session cookies lack the Secure and HTTPOnly security flags. Without these flags, session tokens can be exposed to man-in-the-middle attacks or stolen via JavaScript injection.

Is CVE-2024-47833 being actively exploited?

No, this vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog and no public exploits are available. However, the misconfiguration is straightforward to exploit if discovered.

What versions of Taipy are affected by CVE-2024-47833?

All Taipy versions prior to 4.0.0 are affected. Version 4.0.0 and later contain the remediation.

How do I check if my server is vulnerable to CVE-2024-47833?

Run 'pip show taipy' to check the installed version; if it is below 4.0.0, you are vulnerable. Additionally, inspect HTTP response headers with 'curl -I https://your-app' and look for 'Set-Cookie' headers; if they lack 'Secure' and 'HttpOnly' flags, the vulnerability is present.

Does Defensia detect CVE-2024-47833?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Taipy is installed on a monitored server, CVE-2024-47833 will appear in your dashboard with remediation steps.

Related Python CVEs

CVE-2026-25632CVSS 10EPyT-Flow is a Python package designed for the easy generation of hydraulic and water quality scenario data of water distribution networks. Prior to 0.16.1, EPyT-Flow’s REST API parses attacker-controlled JSON request bodies using a custom deserializer (my_load_from_json) that supports a type field. When type is present, the deserializer dynamically imports an attacker-specified module/class and instantiates it with attacker-supplied arguments. This allows invoking dangerous classes such as subprocess.Popen, which can lead to OS command execution during JSON parsing. This also affects the loading of JSON files. This vulnerability is fixed in 0.16.1.
CVE-2026-34938CVSS 10PraisonAI is a multi-agent teams system. Prior to version 1.5.90, execute_code() in praisonai-agents runs attacker-controlled Python inside a three-layer sandbox that can be fully bypassed by passing a str subclass with an overridden startswith() method to the _safe_getattr wrapper, achieving arbitrary OS command execution on the host. This issue has been patched in version 1.5.90.
CVE-2026-33054CVSS 10Mesop is a Python-based UI framework that allows users to build web applications. Versions 1.2.2 and below contain a Path Traversal vulnerability that allows any user supplying an untrusted state_token through the UI stream payload to arbitrarily target files on the disk under the standard file-based runtime backend. This can result in application denial of service (via crash loops when reading non-msgpack target files as configurations), or arbitrary file manipulation. This vulnerability heavily exposes systems hosted utilizing FileStateSessionBackend. Unauthorized malicious actors could interact with arbitrary payloads overwriting or explicitly removing underlying service resources natively outside the application bounds. This issue has been fixed in version 1.2.3.
CVE-2026-28505CVSS 10Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to version 2.17.0, the str_eval() function in notification_handler.py implements a sandboxed eval() for notification text templates. The sandbox attempts to restrict callable names by inspecting code.co_names of the compiled code object. However, co_names only contains names from the outer code object. When a lambda expression is used, it creates a nested code object whose attribute accesses are stored in code.co_consts, NOT in code.co_names. The sandbox never inspects nested code objects. This issue has been patched in version 2.17.0.
CVE-2026-25115CVSS 9.9n8n is an open source workflow automation platform. Prior to version 2.4.8, a vulnerability in the Python Code node allows authenticated users to break out of the Python sandbox environment and execute code outside the intended security boundary. This issue has been patched in version 2.4.8.
