CVE-2026-31940 1 Chamilo 1 Chamilo Lms 2026-04-17 7.5 High
Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, in main/lp/aicc_hacp.php, user-controlled request parameters are directly used to set the PHP session ID before loading global bootstrap. This leads to session fixation. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.
CVE-2020-1968 5 Canonical, Debian, Fujitsu and 2 more 25 Ubuntu Linux, Debian Linux, M10-1 and 22 more 2026-04-16 3.7 Low
The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL 1.1.1 is not vulnerable to this issue. Fixed in OpenSSL 1.0.2w (Affected 1.0.2-1.0.2v).
CVE-2026-20006 1 Cisco 1 Secure Firewall Threat Defense 2026-04-16 5.8 Medium
A vulnerability in the TLS cryptography functionality of the Snort 3 Detection Engine of Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the Snort 3 Detection Engine to unexpectedly restart, resulting in a denial of service (DoS) condition. This vulnerability is due to improper implementation of the TLS protocol. An attacker could exploit this vulnerability by sending a crafted TLS packet to an affected system. A successful exploit could allow the attacker to cause a device that is running Cisco Secure FTD Software to drop network traffic, resulting in a DoS condition.  Note: TLS 1.3 is not affected by this vulnerability.
CVE-2026-30224 1 Olivetin 1 Olivetin 2026-04-16 5.4 Medium
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, OliveTin does not revoke server-side sessions when a user logs out. Although the browser cookie is cleared, the corresponding session remains valid in server storage until expiry (default ≈ 1 year). An attacker with a previously stolen or captured session cookie can continue authenticating after logout, resulting in a post-logout authentication bypass. This is a session management flaw that violates expected logout semantics. This issue has been patched in version 3000.11.1.
CVE-1999-0428 1 Openssl 1 Openssl 2026-04-16 6.5 Medium
OpenSSL and SSLeay allow remote attackers to reuse SSL sessions and bypass access controls.
CVE-2001-1534 1 Apache 1 Http Server 2026-04-16 N/A
mod_usertrack in Apache 1.3.11 through 1.3.20 generates session ID's using predictable information including host IP address, system time and server process ID, which allows local users to obtain session ID's and bypass authentication when these session ID's are used for authentication.
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-2024-39920 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-2024-2236 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-2024-56529 1 Mailcow 1 Mailcow 2026-04-15 7.1 High
Mailcow through 2024-11b has a session fixation vulnerability in the web panel. It allows remote attackers to set a session identifier when HSTS is disabled on a victim's browser. After a user logs in, they are authenticated and the session identifier is valid. Then, a remote attacker can access the victim's web panel with the same session identifier.
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-2024-22250 2026-04-15 7.8 High
Session Hijack vulnerability in Deprecated VMware Enhanced Authentication Plug-in could allow a malicious actor with unprivileged local access to a windows operating system can hijack a privileged EAP session when initiated by a privileged domain user on the same system.
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-2025-64100 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-2024-11862 2026-04-15 N/A
Non constant time cryptographic operation in Devolutions.XTS.NET 2024.11.19 and earlier allows an attacker to render half of the encryption key obsolete via a timing attacks
CVE-2023-46809 2 Nodejs, Redhat 3 Nodejs, Enterprise Linux, Rhel Eus 2026-04-15 7.4 High
Node.js versions which bundle an unpatched version of OpenSSL or run against a dynamically linked version of OpenSSL which are unpatched are vulnerable to the Marvin Attack - https://people.redhat.com/~hkario/marvin/, if PCKS #1 v1.5 padding is allowed when performing RSA descryption using a private key.
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-2025-71057 1 D-link 1 Wireless N 300 Adsl2+ Modem Router 2026-04-15 8.2 High
Improper session management in D-Link Wireless N 300 ADSL2+ Modem Router DSL-124 ME_1.00 allows attackers to execute a session hijacking attack via spoofing the IP address of an authenticated 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.
