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-2025-28238 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-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-2025-59432 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-2025-29780 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-2025-52689 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-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-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-2024-45368 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-2025-0126 1 Paloaltonetworks 1 Pan-os 2026-04-15 N/A
When configured using SAML, a session fixation vulnerability in the GlobalProtect™ login enables an attacker to impersonate a legitimate authorized user and perform actions as that GlobalProtect user. This requires the legitimate user to first click on a malicious link provided by the attacker. The SAML login for the PAN-OS® management interface is not affected. Additionally, this issue does not affect Cloud NGFW and all Prisma® Access instances are proactively patched.
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-2024-28144 2026-04-15 5.5 Medium
An attacker who can spoof the IP address and the User-Agent of a logged-in user can takeover the session because of flaws in the self-developed session management. If two users access the web interface from the same IP they are logged in as the other user.
CVE-2023-30307 2026-04-15 5.3 Medium
An issue discovered in TP-LINK TL-R473GP-AC, TP-LINK XDR6020, TP-LINK TL-R479GP-AC, TP-LINK TL-R4239G, TP-LINK TL-WAR1200L, and TP-LINK TL-R476G routers allows attackers to hijack TCP sessions which could lead to a denial of service.
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-2024-13176 1 Openssl 1 Openssl 2026-04-15 4.1 Medium
Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations could allow recovering the private key by an attacker. However, measuring the timing would require either local access to the signing application or a very fast network connection with low latency. There is a timing signal of around 300 nanoseconds when the top word of the inverted ECDSA nonce value is zero. This can happen with significant probability only for some of the supported elliptic curves. In particular the NIST P-521 curve is affected. To be able to measure this leak, the attacker process must either be located in the same physical computer or must have a very fast network connection with low latency. For that reason the severity of this vulnerability is Low. The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are affected by this issue.
CVE-2025-26658 2026-04-15 6.8 Medium
The Service Layer in SAP Business One, allows attackers to potentially gain unauthorized access and impersonate other users in the application to perform unauthorized actions. Due to the improper session management, the attackers can elevate themselves to higher privilege and can read, modify and/or write new data. To gain authenticated sessions of other users, the attacker must invest considerable time and effort. This vulnerability has a high impact on the confidentiality and integrity of the application with no effect on the availability of the application.
