CVE-2026-13577

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-2026-13082 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...

JLSEC-2026-689 In the OpenSSL compatibility layer implementation, the function `RAND_poll()` was not behaving as...

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...

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-2026-44040 UltraVNC vncauth.c uses time-seeded libc rand() to generate VNC authentication challenge bytes

UltraVNC through 1.8.2.2 uses a cryptographically weak pseudo-random number generator to produce VNC authentication challenge bytes. In rfb/vncauth.c:119-129, the vncRandomBytes function seeds libc rand with time0 + getpid + rand and generates a 16-byte challenge. The combined seed space is...

GeoVision LPC2011/LPC2211 Web Interface guessable session cookie vulnerability

Summary A guessable session cookie vulnerability exists in the Web Interface functionality of LPC2011/LPC2211 versions: 1.10. A specially crafted series of HTTP requests can lead to an authentication bypas. An attacker can bruteforce session cookies to trigger this vulnerability. Confirmed...

Insecure Randomness

Overview Affected versions of this package are vulnerable to Insecure Randomness via the sendAndReceive function when using a fixed reply queue, due to correlation IDs being generated sequentially by an internal counter. An attacker can intercept or inject unauthorized replies by predicting...

Amazon Linux 2023 : perl-Crypt-PasswdMD5 (ALAS2023-2026-1796)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1796 advisory. Crypt::PasswdMD5 versions through 1.42 for Perl generates insecure random values for salts. The built-in rand function is predictable, and unsuitable for cryptography. CVE-2026-6659 Tenable has extract...
