| CVE-2025-40925 | 2026-04-15 | 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-2025-40931 | 1 Chorny | 1 Apache\ | 2026-04-12 | 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-2025-13044 | 1 Ibm | 1 Concert | 2026-04-07 | N/A | 6.2 MEDIUM |
| IBM Concert 1.0.0 through 2.2.0 creates temporary files with predictable names, which allows local users to overwrite arbitrary files via a symlink attack. | |||||
| CVE-2026-3256 | 1 Ktat | 1 Http\ | 2026-04-01 | N/A | 9.8 CRITICAL |
| HTTP::Session versions through 0.53 for Perl defaults to using insecurely generated session ids. HTTP::Session defaults to using HTTP::Session::ID::SHA1 to generate session ids using a SHA-1 hash seeded with the built-in rand function, the high resolution 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. The distribution includes HTTP::session::ID::MD5 which contains a similar flaw, but uses the MD5 hash instead. | |||||
| CVE-2025-15604 | 1 Tokuhirom | 1 Amon2 | 2026-04-01 | N/A | 9.8 CRITICAL |
| Amon2 versions before 6.17 for Perl use an insecure random_string implementation for security functions. In versions 6.06 through 6.16, the random_string function will attempt to read bytes from the /dev/urandom device, but if that is unavailable then it generates bytes by concatenating a SHA-1 hash seeded with the built-in rand() function, the PID, and the high resolution epoch time. 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. Before version 6.06, there was no fallback when /dev/urandom was not available. Before version 6.04, the random_string function used the built-in rand() function to generate a mixed-case alphanumeric string. This function may be used for generating session ids, generating secrets for signing or encrypting cookie session data and generating tokens used for Cross Site Request Forgery (CSRF) protection. | |||||
| CVE-2025-40926 | 1 Kazeburo | 1 Plack\ | 2026-03-12 | 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-2026-2439 | 1 Bva | 1 Concierge\ | 2026-03-10 | N/A | 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-2026-3255 | 1 Tokuhirom | 1 Http\ | 2026-03-04 | N/A | 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-2025-40932 | 1 Grichter | 1 Apache\ | 2026-03-03 | 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-2025-58424 | 1 F5 | 21 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Advanced Web Application Firewall and 18 more | 2026-02-04 | N/A | 5.3 MEDIUM |
| On BIG-IP systems, undisclosed traffic can cause data corruption and unauthorized data modification in protocols which do not have message integrity protection. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | |||||
| CVE-2025-68701 | 1 Samrocketman | 1 Jervis | 2026-01-20 | N/A | 7.5 HIGH |
| Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, Jervis uses deterministic AES IV derivation from a passphrase. This vulnerability is fixed in 2.2. | |||||
| CVE-2025-69286 | 1 Infiniflow | 1 Ragflow | 2026-01-06 | N/A | 9.8 CRITICAL |
| RAGFlow is an open-source RAG (Retrieval-Augmented Generation) engine. In versions prior to 0.22.0, the use of an insecure key generation algorithm in the API key and beta (assistant/agent share auth) token generation process allows these tokens to be mutually derivable. Specifically, both tokens are generated using the same `URLSafeTimedSerializer` with predictable inputs, enabling an unauthorized user who obtains the shared assistant/agent URL to derive the personal API key. This grants them full control over the assistant/agent owner's account. Version 0.22.0 fixes the issue. | |||||
| CVE-2025-62294 | 1 Soplanning | 1 Soplanning | 2025-11-24 | N/A | 7.5 HIGH |
| SOPlanning is vulnerable to Predictable Generation of Password Recovery Token. Due to weak mechanism of generating recovery tokens, a malicious attacker is able to brute-force all possible values and takeover any account in reasonable amount of time. This issue was fixed in version 1.55. | |||||
| CVE-2024-47945 | 1 Rittal | 4 Cmc Iii Processing Units, Cmc Iii Processing Units Firmware, Iot Interface and 1 more | 2025-11-03 | N/A | 9.8 CRITICAL |
| The devices are vulnerable to session hijacking due to insufficient entropy in its session ID generation algorithm. The session IDs are predictable, with only 32,768 possible values per user, which allows attackers to pre-generate valid session IDs, leading to unauthorized access to user sessions. This is not only due to the use of an (insecure) rand() function call but also because of missing initialization via srand(). As a result only the PIDs are effectively used as seed. | |||||
| CVE-2025-0218 | 1 Pgadmin | 1 Pgagent | 2025-11-03 | N/A | 5.5 MEDIUM |
| When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator is used when generating the directory name, leading to the possibility for a local attacker to pre-create the directory and thus prevent pgAgent from executing jobs, disrupting scheduled tasks. | |||||
| CVE-2024-7558 | 1 Canonical | 1 Juju | 2025-08-26 | N/A | 8.7 HIGH |
| JUJU_CONTEXT_ID is a predictable authentication secret. On a Juju machine (non-Kubernetes) or Juju charm container (on Kubernetes), an unprivileged user in the same network namespace can connect to an abstract domain socket and guess the JUJU_CONTEXT_ID value. This gives the unprivileged user access to the same information and tools as the Juju charm. | |||||
| CVE-2024-10603 | 1 Google | 1 Gvisor | 2025-07-29 | N/A | 5.3 MEDIUM |
| Weaknesses in the generation of TCP/UDP source ports and some other header values in Google's gVisor allowed them to be predicted by an external attacker in some circumstances. | |||||
| CVE-2024-28957 | 1 Nxtech | 6 Cente Ipv6, Cente Ipv6 Snmpv2, Cente Ipv6 Snmpv3 and 3 more | 2025-06-30 | N/A | 5.3 MEDIUM |
| Generation of predictable identifiers issue exists in Cente middleware TCP/IP Network Series. If this vulnerability is exploited, a remote unauthenticated attacker may interfere communications by predicting some packet header IDs of the device. | |||||
