Dancer2 versions through 2.1.0 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...

CVE-2026-16235 Crypt::Password versions through 0.28 for Perl generate insecure random values for salts

Crypt::Password versions through 0.28 for Perl generate insecure random values for salts. These versions use the built-in rand function, which is predictable and unsuitable for cryptography...

CVE-2026-16235

CVE-2026-16235 affects Crypt::Password for Perl up to version 0.28. The root cause is generation of insecure random values for salts by using the built-in rand function, which is predictable and unsuitable for cryptography. This leads to high-severity impact (confidentiality, integrity, availabil...

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...

CVE-2026-13082 GD::SecurityImage versions through 1.75 for Perl use rand to generate secrets

GD::SecurityImage versions through 1.75 for Perl use rand to generate secrets. The random method creates the challenge text used for the CAPTCHA by sampling characters from an array using Perl's built-in rand function, and generates a by default six-character string. The built-in rand function is...

CVE-2026-47085

CVE-2026-47085 affects Cyrus IMAPD (up to 3.12.2). The flaw: URLAUTH token forgery via a missing mboxkey, allowing an attacker who knows a folder name the user never authorized to forge a valid URLAUTH by computing an HMAC-SHA1 with a predictable key, granting read access to the mailbox. Impact i...

DEBIAN-CVE-2026-62294

Flameshot is powerful yet simple to use screenshot software. Prior to 14.0.0, the Open With feature wrote screenshots to a predictable temporary path and followed symlinks, creating a time-of-check to time-of-use race that allowed a local unprivileged attacker on the same machine to pre-plant a...

In the OpenSSL compatibility layer implementation, the function RANDpoll was not behaving as expected and leading to the potential for predictable values returned from RANDbytes after fork is called. This can lead to weak or predictable random numbers generated in applications that are both using...

JLSEC-2026-676 If a TLS 1.3 client gets neither a PSK (pre shared key) extension nor a KSE (key share extension)...

If a TLS 1.3 client gets neither a PSK pre shared key extension nor a KSE key share extension when connecting to a malicious server, a default predictable buffer gets used for the IKM Input Keying Material value when generating the session master secret. Using a potentially known IKM value when...

CVE-2026-62239

FlashAttention through 2.8.3.post1, fixed in commit 0816ef1, contains a symlink attack vulnerability in the downloadandcopy function within hopper/setup.py that extracts NVIDIA toolchain archives without validating symlinks or filtering tar members. A local attacker can pre-plant a symlink in the...

CVE-2026-61500 Rejetto HFS < 3.2.1 Session Forgery via Predictable Signing Key

Rejetto HFS 3.0.0 through 3.2.0 derives its session-cookie signing key from the non-cryptographic Math.random generator and discloses outputs of the same generator to unauthenticated clients during login. A remote attacker can collect a small number of login responses, reconstruct the generator's...

CVE-2026-59930

A flaw was found in Mistune, a Python Markdown parser. The table of contents toc plugin and TableOfContents directive generate heading identifiers IDs as predictable values e.g., tocN without properly processing the heading text. This allows an attacker to control content with a colliding ID, whi...
