CVE-2026-2439 1 Bva 2 Concierge::sessions, Concierge\ 2026-04-17 9.8 Critical
Concierge::Sessions versions from 0.8.1 before 0.8.5 for Perl generate insecure session ids. The generate_session_id function in Concierge::Sessions::Base defaults to using the uuidgen command to generate a UUID, with a fallback to using Perl's built-in rand function. Neither of these methods are secure, and attackers are able to guess session_ids that can grant them access to systems. Specifically, * There is no warning when uuidgen fails. The software can be quietly using the fallback rand() function with no warnings if the command fails for any reason. * The uuidgen command will generate a time-based UUID if the system does not have a high-quality random number source, because the call does not explicitly specify the --random option. Note that the system time is shared in HTTP responses. * UUIDs are identifiers whose mere possession grants access, as per RFC 9562. * The output of the built-in rand() function is predictable and unsuitable for security applications.
CVE-2026-5088 1 Jdeguest 1 Apache::api::password 2026-04-17 7.5 High
Apache::API::Password versions through v0.5.2 for Perl can generate insecure random values for salts. The _make_salt and _make_salt_bcrypt methods will attept to load Crypt::URandom and then Bytes::Random::Secure to generate random bytes for the salt. If those modules are unavailable, it will simply return 16 bytes generated with Perl's built-in rand function. The rand function is unsuitable for cryptographic use. These salts are used for password hashing.
CVE-2026-3255 1 Tokuhirom 2 Http::session2, Http\ 2026-04-17 6.5 Medium
HTTP::Session2 versions before 1.12 for Perl for Perl may generate weak session ids using the rand() function. The HTTP::Session2 session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand() function is unsuitable for cryptographic usage. HTTP::Session2 after version 1.02 will attempt to use the /dev/urandom device to generate a session id, but if the device is unavailable (for example, under Windows), then it will revert to the insecure method described above.
CVE-2025-21617 2026-04-15 N/A
Guzzle OAuth Subscriber signs Guzzle requests using OAuth 1.0. Prior to 0.8.1, Nonce generation does not use sufficient entropy nor a cryptographically secure pseudorandom source. This can leave servers vulnerable to replay attacks when TLS is not used. This vulnerability is fixed in 0.8.1.
CVE-2025-1805 2026-04-15 5.3 Medium
Crypt::Salt for Perl version 0.01 uses insecure rand() function when generating salts for cryptographic purposes.
CVE-2002-20002 2026-04-15 5.4 Medium
The Net::EasyTCP package before 0.15 for Perl always uses Perl's builtin rand(), which is not a strong random number generator, for cryptographic keys.
CVE-2025-26379 1 Johnsoncontrols 5 Iq Panels2, Iq Panels2+, Iqhub and 2 more 2026-04-15 N/A
Use of a weak pseudo-random number generator, which may allow an attacker to read or inject encrypted PowerG packets.
CVE-2024-34538 1 Mateso 1 Passwordsafe 2026-04-15 7.5 High
Mateso PasswordSafe through 8.13.9.26689 has Weak Cryptography.
CVE-2025-27552 2026-04-15 4 Medium
DBIx::Class::EncodedColumn use the rand() function, which is not cryptographically secure to salt password hashes. This vulnerability is associated with program files Crypt/Eksblowfish/Bcrypt.pm. This issue affects DBIx::Class::EncodedColumn until 0.00032.
CVE-2023-31305 2026-04-15 1.9 Low
Generation of weak and predictable Initialization Vector (IV) in PMFW (Power Management Firmware) may allow an attacker with privileges to reuse IV values to reverse-engineer debug data, potentially resulting in information disclosure.
CVE-2025-1860 2026-04-15 7.7 High
Data::Entropy for Perl 0.007 and earlier use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
CVE-2023-50059 2026-04-15 5.3 Medium
An issue ingalxe.com Galxe platform 1.0 allows a remote attacker to obtain sensitive information via the Web3 authentication process of Galxe, the signed message lacks a nonce (random number)
CVE-2024-45751 2026-04-15 5.9 Medium
tgt (aka Linux target framework) before 1.0.93 attempts to achieve entropy by calling rand without srand. The PRNG seed is always 1, and thus the sequence of challenges is always identical.
CVE-2025-40925 1 Starch 1 Starch 2026-04-15 9.1 Critical
Starch versions 0.14 and earlier generate session ids insecurely. The default session id generator returns a SHA-1 hash seeded with a counter, the epoch time, the built-in rand function, the PID, and internal Perl reference addresses. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems.
CVE-2024-56370 2026-04-15 6.5 Medium
Net::Xero 0.044 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically Net::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
CVE-2025-22376 2026-04-15 5.3 Medium
In Net::OAuth::Client in the Net::OAuth package before 0.29 for Perl, the default nonce is a 32-bit integer generated from the built-in rand() function, which is not cryptographically strong.
CVE-2025-2814 2026-04-15 4 Medium
Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. This issue affects operating systems where "/dev/urandom'" is unavailable.  In that case, Crypt::CBC will fallback to use the insecure rand() function.
CVE-2018-25107 2026-04-15 7.5 High
The Crypt::Random::Source package before 0.13 for Perl has a fallback to the built-in rand() function, which is not a secure source of random bits.
CVE-2024-56830 2026-04-15 5.4 Medium
The Net::EasyTCP package 0.15 through 0.26 for Perl uses Perl's builtin rand() if no strong randomization module is present.
CVE-2025-40933 2026-04-15 7.5 High
Apache::AuthAny::Cookie v0.201 or earlier for Perl generates session ids insecurely. Session ids are generated using an MD5 hash of the epoch time and a call to the built-in rand function. The epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems.
