CVE-2025-22275·Python vulnerability

iTerm2 3.5.6 through 3.5.10 before 3.5.11 sometimes allows remote attackers to obtain sensitive information from terminal commands by reading the /tmp/framer.txt file. This can occur for certain it2ssh and SSH Integration configurations, during remote logins to hosts that have a common Python installation.

How to fix this CVE

Update Python to version 3.5.11 or later to patch the temporary file information disclosure vulnerability. Organizations using iTerm2 with SSH integration should prioritize this update to prevent unauthorized access to sensitive terminal command data stored in world-readable temporary files. Ensure all systems with Python installed apply this patch as soon as possible.

sudo dnf update python3

Defensia detects this vulnerability

How to check if you are affected

  1. Step 1: Check installed Python version with 'python3 --version' and verify it is 3.5.11 or newer
  2. Step 2: Examine iTerm2 SSH integration configuration files typically located in ~/.ssh/config and look for it2ssh or SSH Integration directives
  3. Step 3: Search system logs and audit trails for unauthorized access attempts to /tmp/framer.txt using 'grep -r framer.txt /var/log/'
  4. Step 4: Run 'python3 --version' again post-update to confirm the patched version is active, then restart any SSH sessions

FAQ

What is CVE-2025-22275?

CVE-2025-22275 is a critical information disclosure vulnerability in Python versions 3.5.6 through 3.5.10 that allows remote attackers to access sensitive terminal command data through an insufficiently protected temporary file during SSH integration operations. The vulnerability affects systems using iTerm2 with SSH forwarding enabled.

Is CVE-2025-22275 being actively exploited?

No, CVE-2025-22275 is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog and no public exploits are available. However, the vulnerability has a critical CVSS score of 9.3 and should be treated with high priority.

What versions of Python are affected by CVE-2025-22275?

Python versions 3.5.6 through 3.5.10 are vulnerable. The vulnerability was patched in Python 3.5.11 and later releases.

How do I check if my server is vulnerable to CVE-2025-22275?

Run 'python3 --version' to check your installed version. If the output shows version 3.5.6 through 3.5.10, your system is vulnerable and requires immediate patching to 3.5.11 or newer.

Does Defensia detect CVE-2025-22275?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Python is installed on a monitored server, CVE-2025-22275 will appear in your dashboard with remediation steps.

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-2026-33054CVSS 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-2026-25632CVSS 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-2026-8481CVSS 9.9IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the code validation API endpoint. The POST /api/v1/validate/code endpoint accepts user-supplied Python code and executes it directly using Python's built-in exec() function without sandboxing, input validation, or privilege restrictions, enabling any authenticated user to execute arbitrary system commands with the full privileges of the Langflow server process.
