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-2024-56733 2026-04-15 5.7 Medium
Password Pusher is an open source application to communicate sensitive information over the web. A vulnerability has been reported in versions 1.50.3 and prior where an attacker can copy the session cookie before a user logs out, potentially allowing session hijacking. Although the session token is replaced and invalidated upon logout, if an attacker manages to capture the session cookie before this process, they can use the token to gain unauthorized access to the user's session until the token expires or is manually cleared. This vulnerability hinges on the attacker's ability to access the session cookie during an active session, either through a man-in-the-middle attack, by exploiting another vulnerability like XSS, or via direct access to the victim's device. Although there is no direct resolution to this vulnerability, it is recommended to always use the latest version of Password Pusher to best mitigate risk. If self-hosting, ensure Password Pusher is hosted exclusively over SSL connections to encrypt traffic and prevent session cookies from being intercepted in transit. Additionally, implement best practices in local security to safeguard user systems, browsers, and data against unauthorized access.
CVE-2025-28238 2026-04-15 9.8 Critical
Improper session management in Elber REBLE310 Firmware v5.5.1.R , Equipment Model: REBLE310/RX10/4ASI allows attackers to execute a session hijacking attack.
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-2025-59432 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-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-2025-28242 2026-04-15 9.8 Critical
Improper session management in the /login_ok.htm endpoint of DAEnetIP4 METO v1.25 allows attackers to execute a session hijacking attack.
CVE-2024-13967 2026-04-15 8.8 High
This vulnerability allows the successful attacker to gain unauthorized access to a configuration web page delivered by the integrated web Server of EIBPORT. This issue affects EIBPORT V3 KNX: through 3.9.8; EIBPORT V3 KNX GSM: through 3.9.8.
CVE-2024-25977 2026-04-15 7.3 High
The application does not change the session token when using the login or logout functionality. An attacker can set a session token in the victim's browser (e.g. via XSS) and prompt the victim to log in (e.g. via a redirect to the login page). This results in the victim's account being taken over.
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-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.
