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-2025-12390 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-2025-24502 1 Broadcom 1 Symantec Privileged Access Management 2026-04-15 N/A
An improper session validation allows an unauthenticated attacker to cause certain request notifications to be executed in the context of an incorrect user by spoofing the client IP address.
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-2025-27587 1 Openssl 1 Openssl 2026-04-15 5.3 Medium
OpenSSL 3.0.0 through 3.3.2 on the PowerPC architecture is vulnerable to a Minerva attack, exploitable by measuring the time of signing of random messages using the EVP_DigestSign API, and then using the private key to extract the K value (nonce) from the signatures. Next, based on the bit size of the extracted nonce, one can compare the signing time of full-sized nonces to signatures that used smaller nonces, via statistical tests. There is a side-channel in the P-364 curve that allows private key extraction (also, there is a dependency between the bit size of K and the size of the side channel). NOTE: This CVE is disputed because the OpenSSL security policy explicitly notes that any side channels which require same physical system to be detected are outside of the threat model for the software. The timing signal is so small that it is infeasible to be detected without having the attacking process running on the same physical system.
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-2025-52689 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-2025-64100 1 Ckan 1 Ckan 2026-04-15 6.1 Medium
CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.9 and 2.11.4, session ids could be fixed by an attacker if the site is configured with server-side session storage (CKAN uses cookie-based session storage by default). The attacker would need to either set a cookie on the victim's browser or steal the victim's currently valid session. Session identifiers are now regenerated after each login. This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4
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.
CVE-2026-33492 1 Wwbn 1 Avideo 2026-03-25 7.3 High
WWBN AVideo is an open source video platform. In versions up to and including 26.0, AVideo's `_session_start()` function accepts arbitrary session IDs via the `PHPSESSID` GET parameter and sets them as the active PHP session. A session regeneration bypass exists for specific blacklisted endpoints when the request originates from the same domain. Combined with the explicitly disabled session regeneration in `User::login()`, this allows a classic session fixation attack where an attacker can fix a victim's session ID before authentication and then hijack the authenticated session. Commit 5647a94d79bf69a972a86653fe02144079948785 contains a patch.
CVE-2024-0914 2 Opencryptoki Project, Redhat 3 Opencryptoki, Enterprise Linux, Rhel Eus 2026-03-24 5.9 Medium
A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS#1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key.
