CVE-2024-45368 1 Automationdirect 1 H2-dm1e Firmware 2026-04-15 8.8 High
The H2-DM1E PLC's authentication protocol appears to utilize either a custom encoding scheme or a challenge-response protocol. However, there's an observed anomaly in the H2-DM1E PLC's protocol execution, namely its acceptance of multiple distinct packets as valid authentication responses. This behavior deviates from standard security practices where a single, specific response or encoding pattern is expected for successful authentication.
CVE-2025-42602 2026-04-15 N/A
This vulnerability exists in Meon KYC solutions due to improper handling of access and refresh tokens in certain API endpoints of authentication process. A remote attacker could exploit this vulnerability by intercepting and manipulating the responses through API request body leading to unauthorized access of other user accounts.
CVE-2025-29780 2026-04-15 N/A
Post-Quantum Secure Feldman's Verifiable Secret Sharing provides a Python implementation of Feldman's Verifiable Secret Sharing (VSS) scheme. In versions 0.8.0b2 and prior, the `feldman_vss` library contains timing side-channel vulnerabilities in its matrix operations, specifically within the `_find_secure_pivot` function and potentially other parts of `_secure_matrix_solve`. These vulnerabilities are due to Python's execution model, which does not guarantee constant-time execution. An attacker with the ability to measure the execution time of these functions (e.g., through repeated calls with carefully crafted inputs) could potentially recover secret information used in the Verifiable Secret Sharing (VSS) scheme. The `_find_secure_pivot` function, used during Gaussian elimination in `_secure_matrix_solve`, attempts to find a non-zero pivot element. However, the conditional statement `if matrix[row][col] != 0 and row_random < min_value:` has execution time that depends on the value of `matrix[row][col]`. This timing difference can be exploited by an attacker. The `constant_time_compare` function in this file also does not provide a constant-time guarantee. The Python implementation of matrix operations in the _find_secure_pivot and _secure_matrix_solve functions cannot guarantee constant-time execution, potentially leaking information about secret polynomial coefficients. An attacker with the ability to make precise timing measurements of these operations could potentially extract secret information through statistical analysis of execution times, though practical exploitation would require significant expertise and controlled execution environments. Successful exploitation of these timing side-channels could allow an attacker to recover secret keys or other sensitive information protected by the VSS scheme. This could lead to a complete compromise of the shared secret. As of time of publication, no patched versions of Post-Quantum Secure Feldman's Verifiable Secret Sharing exist, but other mitigations are available. As acknowledged in the library's documentation, these vulnerabilities cannot be adequately addressed in pure Python. In the short term, consider using this library only in environments where timing measurements by attackers are infeasible. In the medium term, implement your own wrappers around critical operations using constant-time libraries in languages like Rust, Go, or C. In the long term, wait for the planned Rust implementation mentioned in the library documentation that will properly address these issues.
CVE-2025-22216 2026-04-15 5.4 Medium
A UAA configured with multiple identity zones, does not properly validate session information across those zones. A User authenticated against a corporate IDP can re-use their jsessionid to access other zones.
CVE-2025-4644 1 Payloadcms 1 Payload 2026-04-15 N/A
A Session Fixation vulnerability existed in Payload's SQLite adapter due to identifier reuse during account creation. A malicious attacker could create a new account, save its JSON Web Token (JWT), and then delete the account, which did not invalidate the JWT. As a result, the next newly created user would receive the same identifier, allowing the attacker to reuse the JWT to authenticate and perform actions as that user. This issue has been fixed in version 3.44.0 of Payload.
CVE-2025-59432 1 Ongres 1 Scram 2026-04-15 6.8 Medium
SCRAM (Salted Challenge Response Authentication Mechanism) is part of the family of Simple Authentication and Security Layer (SASL, RFC 4422) authentication mechanisms. Prior to version 3.2, a timing attack vulnerability exists in the SCRAM Java implementation. The issue arises because Arrays.equals was used to compare secret values such as client proofs and server signatures. Since Arrays.equals performs a short-circuit comparison, the execution time varies depending on how many leading bytes match. This behavior could allow an attacker to perform a timing side-channel attack and potentially infer sensitive authentication material. All users relying on SCRAM authentication are impacted. This vulnerability has been patched in version 3.1 by replacing Arrays.equals with MessageDigest.isEqual, which ensures constant-time comparison.

CVE-2025-24503 2026-04-15 N/A
A malicious actor can fix the session of a PAM user by tricking the user to click on a specially crafted link to the PAM server.
CVE-2025-52689 2026-04-15 9.8 Critical
Successful exploitation of the vulnerability could allow an unauthenticated attacker to obtain a valid session ID with administrator privileges by spoofing the login request, potentially allowing the attacker to modify the behaviour of the access point.
CVE-2024-39920 1 Ietf 1 Tcp 2026-04-15 4.3 Medium
The TCP protocol in RFC 9293 has a timing side channel that makes it easier for remote attackers to infer the content of one TCP connection from a client system (to any server), when that client system is concurrently obtaining TCP data at a slow rate from an attacker-controlled server, aka the "SnailLoad" issue. For example, the attack can begin by measuring RTTs via the TCP segments whose role is to provide an ACK control bit and an Acknowledgment Number.
CVE-2025-70973 1 Scadabr 1 Scadabr 2026-04-07 4.8 Medium
ScadaBR 1.12.4 is vulnerable to Session Fixation. The application assigns a JSESSIONID session cookie to unauthenticated users and does not regenerate the session identifier after successful authentication. As a result, a session created prior to login becomes authenticated once the victim logs in, allowing an attacker who knows the session ID to hijack an authenticated session.

In Mbed TLS through 4.0.0, there is a compiler-induced timing side channel (in RSA and CBC/ECB decryption) that only occurs with LLVM's select-optimize feature. TF-PSA-Crypto through 1.0.0 is also affected.
CVE-2026-25101 1 Bludit 1 Bludit 2026-04-03 9.8 Critical
Bludit allows user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behavior enables an attacker to fix a session ID for a victim and later hijack the authenticated session. This issue was fixed in version 3.17.2.
CVE-2026-33946 2 Lfprojects, Modelcontextprotocol 2 Mcp Ruby Sdk, Ruby-sdk 2026-04-02 5.9 Medium
MCP Ruby SDK is the official Ruby SDK for Model Context Protocol servers and clients. Prior to version 0.9.2, the Ruby SDK's streamable_http_transport.rb implementation contains a session hijacking vulnerability. An attacker who obtains a valid session ID can completely hijack the victim's Server-Sent Events (SSE) stream and intercept all real-time data. Version 0.9.2 contains a patch.
CVE-2024-7341 1 Redhat 8 Build Keycloak, Build Of Keycloak, Enterprise Linux and 5 more 2026-04-01 7.1 High
A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
CVE-2026-33757 1 Openbao 1 Openbao 2026-04-01 9.6 Critical
OpenBao is an open source identity-based secrets management system. Prior to version 2.5.2, OpenBao does not prompt for user confirmation when logging in via JWT/OIDC and a role with `callback_mode` set to `direct`. This allows an attacker to start an authentication request and perform "remote phishing" by having the victim visit the URL and automatically log-in to the session of the attacker. Despite being based on the authorization code flow, the `direct` mode calls back directly to the API and allows an attacker to poll for an OpenBao token until it is issued. Version 2.5.2 includes an additional confirmation screen for `direct` type logins that requires manual user interaction in order to finish the authentication. This issue can be worked around either by removing any roles with `callback_mode=direct` or enforcing confirmation for every session on the token issuer side for the Client ID used by OpenBao.
