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-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-2024-2236 1 Redhat 2 Enterprise Linux, Rhel Eus 2026-04-15 5.9 Medium
A timing-based side-channel flaw was found in libgcrypt's RSA implementation. This issue may allow a remote attacker to initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts.
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-2024-2639 2026-04-15 4.3 Medium
A vulnerability was found in Bdtask Wholesale Inventory Management System up to 20240311. It has been declared as problematic. Affected by this vulnerability is an unknown functionality. The manipulation leads to session fixiation. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-257245 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-12390 1 Redhat 1 Build Keycloak 2026-04-15 6 Medium
A flaw was found in Keycloak. In Keycloak where a user can accidentally get access to another user's session if both use the same device and browser. This happens because Keycloak sometimes reuses session identifiers and doesn’t clean up properly during logout when browser cookies are missing. As a result, one user may receive tokens that belong to another user.
CVE-2023-52268 1 Freescout Helpdesk 1 Freescout 2026-04-15 9.1 Critical
The End-User Portal module before 1.0.65 for FreeScout sometimes allows an attacker to authenticate as an arbitrary user because a session token can be sent to the /auth endpoint. NOTE: this module is not part of freescout-helpdesk/freescout on GitHub.
CVE-2020-36913 1 All-dynamics 1 Digital Signage System 2026-04-15 5.3 Medium
All-Dynamics Software enlogic:show 2.0.2 contains a session fixation vulnerability that allows attackers to set a predefined PHP session identifier during the login process. Attackers can forge HTTP GET requests to welcome.php with a manipulated session token to bypass authentication and potentially execute cross-site request forgery attacks.
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-2025-70973 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.
CVE-2023-53776 1 Dbbroadcast 3 Sft Dab 600\/c, Sft Dab 600\/c Firmware, Sft Dab Series 2026-04-07 8.8 High
Screen SFT DAB 1.9.3 contains an authentication bypass vulnerability that allows attackers to exploit weak session management by reusing IP-bound session identifiers. Attackers can issue unauthorized requests to the device management API by leveraging the session binding mechanism to perform critical operations on the transmitter.
CVE-2023-53775 1 Dbbroadcast 3 Sft Dab 600\/c, Sft Dab 600\/c Firmware, Sft Dab Series 2026-04-07 6.5 Medium
Screen SFT DAB 1.9.3 contains an authentication bypass vulnerability that allows attackers to change user passwords by exploiting weak session management controls. Attackers can reuse IP-bound session identifiers to issue unauthorized requests to the userManager API and modify user credentials without proper authentication.
CVE-2023-53741 1 Dbbroadcast 11 Sft Dab 015\/c, Sft Dab 015\/c Firmware, Sft Dab 050\/c and 8 more 2026-04-07 8.1 High
Screen SFT DAB 1.9.3 contains a weak session management vulnerability that allows attackers to bypass authentication controls by reusing IP address-bound session identifiers. Attackers can exploit the vulnerable API by intercepting and reusing established sessions to remove user accounts without proper authorization.
CVE-2025-66442 2 Arm, Mbed-tls 4 Mbed Tls, Tf-psa-crypto, Mbedtls and 1 more 2026-04-07 5.1 Medium
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.
CVE-2025-55266 2 Hcl, Hcltech 2 Aftermarket Dpc, Aftermarket Cloud 2026-03-27 5.9 Medium
HCL Aftermarket DPC is affected by Session Fixation which allows attacker to takeover the user's session and use it carry out unauthorized transaction behalf of the user.
