CVE-2025-46653 1 Node-formidable 1 Formidable 2026-06-17 N/A 3.1 LOW
Formidable (aka node-formidable) 2.1.0 through 3.x before 3.5.3 relies on hexoid to prevent guessing of filenames for untrusted executable content; however, hexoid is documented as not "cryptographically secure." (Also, there is a scenario in which only the last two characters of a hexoid string need to be guessed, but this is not often relevant.) NOTE: this does not imply that, in a typical use case, attackers will be able to exploit any hexoid behavior to upload and execute their own content.
CVE-2025-40932 1 Grichter 1 Apache\ 2026-06-17 N/A 8.2 HIGH
Apache::SessionX versions through 2.01 for Perl create insecure session id. Apache::SessionX generates session ids insecurely. The default session id generator in Apache::SessionX::Generate::MD5 returns a MD5 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. Predicable session ids could allow an attacker to gain access to systems.
CVE-2025-40931 1 Chorny 1 Apache\ 2026-06-17 N/A 9.1 CRITICAL
Apache::Session::Generate::MD5 versions through 1.94 for Perl create insecure session id. Apache::Session::Generate::MD5 generates session ids insecurely. The default session id generator returns a MD5 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. Predicable session ids could allow an attacker to gain access to systems. Note that the libapache-session-perl package in some Debian-based Linux distributions may be patched to use Crypt::URandom.
CVE-2025-40926 1 Kazeburo 1 Plack\ 2026-06-17 N/A 9.8 CRITICAL
Plack::Middleware::Session::Simple versions before 0.05 for Perl generates session ids insecurely. The default 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. Predictable session ids could allow an attacker to gain access to systems. Plack::Middleware::Session::Simple is intended to be compatible with Plack::Middleware::Session, which had a similar security issue CVE-2025-40923.
CVE-2025-40925 2026-06-17 N/A 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-2025-40924 2026-06-17 N/A 6.5 MEDIUM
Catalyst::Plugin::Session before version 0.44 for Perl generates session ids insecurely. The session id is generated from a (usually SHA-1) hash of a simple counter, the epoch time, the built-in rand function, the PID and the current Catalyst context. This information is of low entropy. 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-2025-40923 2026-06-17 N/A 7.3 HIGH
Plack-Middleware-Session before version 0.35 for Perl generates session ids insecurely. The default 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. Predicable session ids could allow an attacker to gain access to systems.
CVE-2025-40920 2026-06-17 N/A 8.6 HIGH
Catalyst::Authentication::Credential::HTTP versions 1.018 and earlier for Perl generate nonces using the Perl Data::UUID library. * Data::UUID does not use a strong cryptographic source for generating UUIDs. * Data::UUID returns v3 UUIDs, which are generated from known information and are unsuitable for security, as per RFC 9562. * The nonces should be generated from a strong cryptographic source, as per RFC 7616.
CVE-2025-40919 2026-06-17 N/A 6.5 MEDIUM
Authen::DigestMD5 versions 0.01 through 0.02 for Perl generate the cnonce insecurely. The cnonce (client nonce) is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. 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. According to RFC 2831, "The cnonce-value is an opaque quoted string value provided by the client and used by both client and server to avoid chosen plaintext attacks, and to provide mutual authentication. The security of the implementation depends on a good choice. It is RECOMMENDED that it contain at least 64 bits of entropy."
CVE-2025-40918 2026-06-17 N/A 6.5 MEDIUM
Authen::SASL::Perl::DIGEST_MD5 versions 2.04 through 2.1800 for Perl generates the cnonce insecurely. The cnonce (client nonce) is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. 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. According to RFC 2831, The cnonce-value is an opaque quoted string value provided by the client and used by both client and server to avoid chosen plaintext attacks, and to provide mutual authentication. The security of the implementation depends on a good choice. It is RECOMMENDED that it contain at least 64 bits of entropy.
CVE-2025-40916 2026-06-17 N/A 9.1 CRITICAL
Mojolicious::Plugin::CaptchaPNG version 1.05 for Perl uses a weak random number source for generating the captcha. That version uses the built-in rand() function for generating the captcha text as well as image noise, which is insecure.
CVE-2025-40915 2026-06-17 N/A 7.0 HIGH
Mojolicious::Plugin::CSRF 1.03 for Perl uses a weak random number source for generating CSRF tokens. That version of the module generates tokens as an MD5 of the process id, the current time, and a single call to the built-in rand() function.
CVE-2025-40905 1 Dbook 1 Www\ 2026-06-17 N/A 7.3 HIGH
WWW::OAuth 1.000 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
CVE-2025-3495 2026-06-17 N/A 9.8 CRITICAL
Delta Electronics COMMGR v1 and v2 uses insufficiently randomized values to generate session IDs (CWE-338). An attacker could easily brute force a session ID and load and execute arbitrary code.
CVE-2025-32755 1 Jenkins 1 Ssh-slave 2026-06-17 N/A 9.1 CRITICAL
In jenkins/ssh-slave Docker images based on Debian, SSH host keys are generated on image creation for images based on Debian, causing all containers based on images of the same version use the same SSH host keys, allowing attackers able to insert themselves into the network path between the SSH client (typically the Jenkins controller) and SSH build agent to impersonate the latter.
CVE-2025-32754 1 Jenkins 1 Ssh-agent 2026-06-17 N/A 9.1 CRITICAL
In jenkins/ssh-agent Docker images 6.11.1 and earlier, SSH host keys are generated on image creation for images based on Debian, causing all containers based on images of the same version use the same SSH host keys, allowing attackers able to insert themselves into the network path between the SSH client (typically the Jenkins controller) and SSH build agent to impersonate the latter.
CVE-2025-2814 2026-06-17 N/A 4.0 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-2025-27552 2026-06-17 N/A 4.0 MEDIUM
