CVE-2026-54466

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, the frame format in draft versions of the WebSocket protocol includes a length header that allows an arbitrarily large integer to be encoded as a sequence of bytes with the high bit set. By sending an indefinite...

Security Bulletin: IBM Cloud Pak for Data System (CPDS 1.0) is affected by a Denial of Service vulnerability due to pyasn1

Summary pyasn1 is used by IBM Cloud Pak for Data System 1.0 as a generic ASN.1 encoding and decoding library for Python applications. CVE-2026-30922 affects pyasn1's ASN.1 decoder, where processing of crafted payloads containing deeply nested SEQUENCE or SET tags with indefinite length markers...

Astra Linux – Vulnerability in pyasn1

pyasn1 is a generic ASN.1 library for Python. Prior to version 0.6.3, the pyasn1 library was vulnerable to a Denial of Service DoS attack caused by uncontrolled recursion during the decoding of ASN.1 data with deeply nested structures. An attacker could provide a crafted payload containing...
