Not enough EPSS history yet.
The Jakarta Security OpenID Connect authentication mechanism generates the state and nonce values with a non-cryptographic random number generator and insufficient entropy. A remote attacker who predicts these values can forge an authentication callback that logs a victim into the attacker's account, and the replay protection for ID tokens is weakened. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

CVE-2026-111259——
——0The embedded server generates HTTP session identifiers with a non-cryptographic random number generator by default. A remote attacker who observes a session identifier can predict the identifiers issued to other users and hijack their sessions, if the application relies on HTTP sessions for authentication. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.14hCVE-2026-1253623.1 LOW17.6%
——5Seahub through 14.0.10 contains a weak randomness vulnerability in MultiShareLinksBatch.post() that generates batch share link passwords using Python's non-cryptographic random.choices(). Authenticated users permitted to create share links can request many generated passwords via the multi-share-links batch endpoint, recover the Mersenne Twister state, and predict other users' share link passwords.1dCVE-2026-173935.1 MED2.9%
——1IBM API Connect 10.0.8.0 through 10.0.8.12 could allow a local attacker to obtain sensitive information due to the use of a cryptographically weak pseudo-random number generator.3dCVE-2026-173868.1 HIG41.8%
——13IBM API Connect 10.0.8.0 through 10.0.8.12 could allow a remote attacker to gain full administrative control due to the use of a cryptographically weak pseudo-random number generator.1dCVE-2026-1215534.8 MED29.5%
——9Cotonti through 1.0.0 generates registration and email-change validation tokens with md5(microtime()), allowing attackers to bypass email-ownership verification by predicting tokens. Attackers can derive the generation time from the HTTP Date header and compute candidate tokens offline. They then submit these tokens to the users.register.php validate handler to activate accounts or confirm email addresses they do not control.4dCVE-2026-1189867.5 HIG25.0%
——8CallBackery versions before 0.62.0 for Perl allow session cookie forgery via a signing secret generated with rand().
The secret that signs session cookies is built from two calls to the built-in rand(), which is seeded with 32 bits. The secret therefore has at most 2**32 possible values, and one signed cookie is enough to test each candidate offline.
An attacker who obtains a single session cookie can recover the secret and sign cookies for any user, including an administrator.5d
