3 known CVE vulnerabilities in AIOHTTP (biblioteka asynchronicznego klienta/serwera HTTP dla Pythona), translated and rated.
- CVE-2026-54275High
In the AIOHTTP library before version 3.14.1, a vulnerability was found that allows bypassing the TLS SNI check for the server_hostname parameter when reusing an existing connection. If an application makes multiple requests to the same domain but with different server_hostname values, later calls may incorrectly reuse the previous connection instead of being rejected.
- CVE-2026-54273High
In the AIOHTTP library before version 3.14.1, there was no limit on the number of pipelined requests that could be queued. An attacker can exploit this to cause excessive memory usage, potentially leading to a DoS attack.
- CVE-2026-50269High
In the AIOHTTP library before version 3.14.0, a vulnerability allows HTTP header injection through attacker-controlled input included in multipart/payload headers. If an application passes user-controlled strings into `MultipartWriter.append(headers=...)` or `Payload.headers`, an attacker may modify the request to inject headers or change its contents.
