urwid: Urwid: Predictable session IDs lead to remote code execution and information disclosure

A flaw was found in the urwid web display backend. This vulnerability arises from the use of a cryptographically insecure pseudo-random number generator PRNG for web session identifiers, making them predictable. An attacker could either observe enough session IDs to reconstruct the PRNG state or,...

RHEL 8 : python-urwid (RHSA-2026:57637)

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2026:57637 advisory. Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic da...

SUSE CVE-2026-9323

The urwid web display backend urwid/display/web.py generates web session identifiers urwidid in Screen.start by concatenating two random.randrange109 calls that use Python's Mersenne Twister PRNG, which is not cryptographically secure. Each call consumes approximately 30 bits of PRNG state, and t...

Amazon Linux 2 : perl-CGI-Session, --advisory ALAS2-2026-3805 (ALAS-2026-3805)

The version of perl-CGI-Session installed on the remote host is prior to 4.35-16. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3805 advisory. CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources. The...

CVE-2026-13577

Dancer2 versions before 2.2.0 for Perl generate insecure session ids when required CSPRNG modules are unavailable. Dancer2::Core::Role::SessionFactory::generateid silently falls back to a built-in rand-derived session id unless both Math::Random::ISAAC::XS and Crypt::URandom are available. The...

Linux Distros Unpatched Vulnerability : CVE-2026-38968

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking. HTTP session identifiers in src/HTTPserver.cpp use weak...

AZL-92103 CVE-2026-38968 affecting package ntopng 5.2.1-6

ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking. HTTP session identifiers in src/HTTPserver.cpp use weak time-seeded pseudo-randomness during session creation. As a result, fresh authenticated logins can receive deterministic or colliding...
