CVE-2025-69226: Aiohttp Remote Code Execution Vulnerability
LOWCVE-2025-69226 is a LOW remote code execution vulnerability (CWE-202: Exposure of Sensitive Information Through Data Queries) affecting Aiohttp libraries in the PyPI ecosystem. The issue involves aiohttp vulnerable to brute-force leak of internal static file path components. Remediation is available by upgrading affected packages to version 3.13.3.
CVE-2025-69226 at a Glance
How to Fix CVE-2025-69226
To remediate this vulnerability, upgrade all affected Aiohttp dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install aiohttp>=3.13.3
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show aiohttp
How to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2025-69226, inspect your installed packages using pip:
pip show aiohttp
Analyze the terminal output to locate any version of Aiohttp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.13.3), your application is affected.
Note: The pip show aiohttp command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-202: Exposure of Sensitive Information Through Data Queries, where when trying to keep information confidential, an attacker can often infer some of the information by using statistics.
