PT-2026-56548

Name of the Vulnerable Software and Affected Versions httplib2 versions prior to 0.32.0 Description An issue exists where the library performs unbounded decompression of HTTP response bodies encoded with Content-Encoding: gzip or deflate within the decompressContent function in httplib2/init.py. ...

CVE-2026-58472

GNU Wget up to 1.25.0 contains a heap buffer overflow in html_quote_string() (src/convert.c) triggered by a server-supplied HTML attribute with extensive entity encoding. The root cause is a signed integer counter overflow during output size accumulation, leading to an undersized heap allocation ...

CVE-2026-58472 GNU Wget 1.25.0 Heap Buffer Overflow via HTML Attribute Encoding

GNU Wget through 1.25.0, fixed in commit dd692d9, contains a heap buffer overflow vulnerability in the htmlquotestring function in src/convert.c that allows a remote attacker to trigger memory corruption by supplying a crafted HTML attribute with a large number of characters requiring entity...

PYSEC-2026-1996 Decompression-bomb safeguards bypassed when following HTTP redirects (streaming API)

Impact urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header e.g., gzip,...

PYSEC-2026-1998 urllib3 allows an unbounded number of links in the decompression chain

Impact urllib3 supports chained HTTP encoding algorithms for response content according to RFC 9110 e.g., Content-Encoding: gzip, zstd. However, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps...

PYSEC-2026-1846 python-ldap is Vulnerable to Improper Encoding or Escaping of Output and Improper Null Termination

Summary ldap.dn.escapednchars escapes \x00 incorrectly by emitting a backslash followed by a literal NUL byte instead of the RFC-4514 hex form \00. Any application that uses this helper to construct DNs from untrusted input can be made to consistently fail before a request is sent to the LDAP...

PYSEC-2026-1854 python-socketio vulnerable to arbitrary Python code execution (RCE) through malicious pickle deserialization in certain multi-server deployments

Summary 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...

PYSEC-2026-1104 AIOHTTP is vulnerable to HTTP Request/Response Smuggling through incorrect parsing of chunked trailer sections

Summary The Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. Impact If a pure Python version of aiohttp is installed i.e. without the usual C extensions or AIOHTTPNOEXTENSIONS is enabled, then an attacker may be able to execu...

PYSEC-2026-1433 Gunicorn HTTP Request/Response Smuggling vulnerability

Gunicorn version 21.2.0 does not properly validate the value of the 'Transfer-Encoding' header as specified in the RFC standards, which leads to the default fallback method of 'Content-Length,' making it vulnerable to TE.CL request smuggling. This vulnerability can lead to cache poisoning, data...

PYSEC-2026-1779 PheonixAppAPI has visible Encoding Maps

Impact This is a kind of moderate issue. The impact is not big for normal users but can be for users who want to secure their code/files/etc. The issue is that the map of encoding/decoding languages are visible in code. Patches The Problem was patched in 0.2.5, so you should try to upgrade to the...

freerdp: FreeRDP: Out-of-bounds write in planar bitmap decoder allows arbitrary code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The planar bitmap decoder contains an out-of-bounds heap write vulnerability when processing RLE planar data. A remote attacker could exploit this by providing specially crafted RLE planar data, leading to an...

PYSEC-2026-1645 Undefined Behavior in mlflow

A vulnerability in mlflow/mlflow version 2.11.1 allows attackers to create multiple models with the same name by exploiting URL encoding. This flaw can lead to Denial of Service DoS as an authenticated user might not be able to use the intended model, as it will open a different model each time...

PYSEC-2026-1434 Request smuggling leading to endpoint restriction bypass in Gunicorn

Gunicorn fails to properly validate Transfer-Encoding headers, leading to HTTP Request Smuggling HRS vulnerabilities. By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn's handli...
