AZL-109887 CVE-2026-111064 affecting package python-aiohttp 3.6.2-3

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, keepalive timeout handling is absent during the initial portion of a request. An attacker can keep an idle connection open indefinitely before sending any request data, consuming server connection...

DEBIAN-CVE-2026-111748

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, an attacker can send an absolute-form request that causes Request.scheme to use attacker-controlled request-target scheme data instead of the connection protocol. Applications that use Request.scheme...

Mercury: Stored / DOM Cross-Site Scripting (XSS): mr.Markdown renders untrusted content as raw, unsanitized HTML

Summary Mercury turns Jupyter notebooks into shared web apps/dashboards. The mr.Markdown widget converts its input to HTML with python-markdown and no sanitization step. MarkdownWidget is an ipywidgets.HTML widget, whose value is written to the page as raw HTML via innerHTML with no sanitization,...

CVE-2026-111065

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, Max-Age processing can overflow and skip closing a connection. An attacker can consequently exhaust the connection pool temporarily until garbage collection resolves the connections. This issue is fix...

CVE-2026-111064 aiohttp server lacks an initial request/header timeout

CVE-2026-111063

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the Secure attribute for a shared cookie is not enforced. An attacker can consequently cause a shared cookie marked Secure to be sent with an unencrypted request. This issue is fixed in version 3.14.4...

python: python: Arbitrary file deletion via race condition during temporary directory cleanup

A flaw was found in Python. A race condition during the cleanup of temporary directories allows a local attacker with write access to replace a directory with a symbolic link a reference pointing to another location. This can lead to unauthorized deletion or alteration of files outside the...

python: Use-after-free of a server-side SSLContext when sni_callback switches contexts

A flaw was found in Python. A remote, unauthenticated TLS client can cause a use-after-free in a server that uses SSLContext.snicallback to assign a different SSLSocket.context when selecting a certificate per server name, if nothing else keeps the original SSLContext alive. This can crash the...

python: python: Certificate verification bypass via missing server_hostname validation in SSLContext.wrap_bio()

A flaw was found in Python. When establishing secure connections using the SSLContext.wrapbio function with hostname checking enabled, the module fails to validate that a target server hostname is supplied. Because of this missing check, certificate hostname verification is silently skipped rathe...
