A remote code execution vulnerability in python-socketio versions prior to 5.14.0 allows attackers to execute arbitrary Python code through malicious pickle deserialization in multi-server deployments on which the attacker previously gained access to the message queue that the servers use for internal communications. When Socket.IO servers are configured to use a message queue backend such as Redis for inter-server communication, messages sent between the servers are encoded using the `pickle` Python module. When a server receives one of these messages through the message queue, it assumes it is trusted and immediately deserializes it. The vulnerability stems from deserialization of messages using Python's `pickle.loads()` function. Having previously obtained access to the message queue, the attacker can send a python-socketio server a crafted pickle payload that executes arbitrary code during deserialization via Python's `__reduce__` method. This vulnerability only affects deployments with a compromised message queue. The attack can lead to the attacker executing random code in the context of, and with the privileges of a Socket.IO server process. Single-server systems that do not use a message queue, and multi-server systems with a secure message queue are not vulnerable. In addition to making sure standard security practices are followed in the deployment of the message queue, users of the python-socketio package can upgrade to version 5.14.0 or newer, which remove the `pickle` module and use the much safer JSON encoding for inter-server messaging.","severity":{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00482,"percentile":0.41884,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":true,"fix_available":true},"cwes":["CWE-502"],"published":"2025-10-06T16:04:22Z","modified":"2026-10-28T02:31:06Z","exploits":[{"source":"pocgithub","id":"locus-x64/CVE-2025-61765_PoC","title":"locus-x64/CVE-2025-61765_PoC","date":"2025-10-17","url":"https://github.com/locus-x64/CVE-2025-61765_PoC"}],"fixes":[{"ecosystem":"PyPI","package":"python-socketio","fixed_in":["5.14.0"],"sources":["ghsa","osv"]},{"ecosystem":"Debian:14","package":"python-socketio","fixed_in":["5.16.0-1"],"sources":["osv"]},{"ecosystem":"SUSE:Linux

The attack can lead to the attacker executing random code in the context of, and with the privileges of a Socket.IO server process. \n\nSingle-server systems that do not use a message queue, and multi-server systems with a secure message queue are not vulnerable.\n\n### Remediation\nIn addition to making sure standard security practices are followed in the deployment of the message queue, users of the python-socketio package can upgrade to version 5.14.0 or newer, which remove the `pickle` module and use the much safer JSON encoding for inter-server messaging.","status":"published","published":"2026-07-07T16:03:06.734448Z","modified":"2026-07-07T17:48:07.999163508Z","cvss":[{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L","level":"medium"}],"updated_at":"2026-11-02T15:52:55.06457Z"},{"id":"UBUNTU-CVE-2025-61765","description":"python-socketio is a Python implementation of the Socket.IO realtime client and server. A remote code execution vulnerability in python-socketio versions prior to 5.14.0 allows attackers to execute arbitrary Python code through malicious pickle deserialization in multi-server deployments on which the attacker previously gained access to the message queue that the servers use for internal communications. When Socket.IO servers are configured to use a message queue backend such as Redis for inter-server communication, messages sent between the servers are encoded using the `pickle` Python module.
