aiohttp - Directory Traversal

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. When using aiohttp as a web server and configuring static routes, it is necessary to specify the root path for static files. Additionally, the option 'followsymlinks' can be used to determine whether to follow symboli...

BIT-PYTHON-2026-5713 Out-of-bounds read/write during remote profiling and asyncio process introspection when connecting to malicious target

The "profiling.sampling" module Python 3.15+ and "asyncio introspection capabilities" 3.14+, "python -m asyncio ps" and "python -m asyncio pstree" features could be used to read and write addresses in a privileged process if that process connected to a malicious or "infected" Python process via t...

BIT-PYTHON-MIN-2026-3298 Out-of-bounds write in Windows asyncio.ProacterEventLoop.sock_recvfrom_into() when using nbytes

The method "sockrecvfrominto" of "asyncio.ProacterEventLoop" Windows only was missing a boundary check for the data buffer when using nbytes parameter. This allowed for an out-of-bounds buffer write if data was larger than the buffer size. Non-Windows platforms are not affected...

EUVD-2025-210419

picklescan before 0.0.30 fails to detect the asyncio.unixevents.UnixSubprocessTransport.start function in pickle reduce methods, allowing remote code execution. Attackers can craft malicious pickle files embedding this built-in function that evade detection but execute arbitrary commands when...

CVE-2025-71364

CVE-2025-71364 affects picklescan prior to 0.0.30, which fails to detect the builtin function asyncio.unix_events._UnixSubprocessTransport._start inside pickle reduce methods. This allows an attacker to craft malicious pickle payloads that evade detection and execute arbitrary commands upon loadi...

UBUNTU-CVE-2026-54273

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, no limit was present on the number of pipelined requests that could be queued. An attacker may be able to use pipelined requests to use excessive amounts of memory, potentially leading to DoS. This...

UBUNTU-CVE-2026-54276

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, DigestAuthMiddleware can send an authentication response after following a cross-origin redirect. This likely requires an open redirect vulnerability or similar on the target domain for an attacker to...
