CVE-2024-11084 1 Perforce 1 Helix Alm 2026-04-15 N/A
Helix ALM prior to 2025.1 returns distinct error responses during authentication, allowing an attacker to determine whether a username exists.
CVE-2024-28885 2026-04-15 5.9 Medium
Observable discrepancy in some Intel(R) QAT Engine for OpenSSL software before version v1.6.1 may allow information disclosure via network access.
CVE-2024-48644 1 Reolink 1 Duo 2 Wifi Camera Firmware 2026-04-15 5.3 Medium
Accounts enumeration vulnerability in the Login Component of Reolink Duo 2 WiFi Camera (Firmware Version v3.0.0.1889_23031701) allows remote attackers to determine valid user accounts via login attempts. This can lead to the enumeration of user accounts and potentially facilitate other attacks, such as brute-forcing of passwords. The vulnerability arises from the application responding differently to login attempts with valid and invalid usernames.
CVE-2025-1468 2026-04-15 7.5 High
An unauthenticated remote attacker can gain access to sensitive information including authentication information when using CODESYS OPC UA Server with the non-default Basic128Rsa15 security policy.
CVE-2021-47664 2026-04-15 5.3 Medium
Due to improper authentication mechanism an unauthenticated remote attacker can enumerate valid usernames.
CVE-2024-54002 1 Dependencytrack 1 Dependency-track 2026-04-15 5.3 Medium
Dependency-Track is a Component Analysis platform that allows organizations to identify and reduce risk in the software supply chain. Performing a login request against the /api/v1/user/login endpoint with a username that exist in the system takes significantly longer than performing the same action with a username that is not known by the system. The observable difference in request duration can be leveraged by actors to enumerate valid names of managed users. LDAP and OpenID Connect users are not affected. The issue has been fixed in Dependency-Track 4.12.2.
CVE-2025-9031 1 Netdatasoft 1 Divvy Drive 2026-04-15 4.3 Medium
Observable Timing Discrepancy vulnerability in DivvyDrive Information Technologies Inc. DivvyDrive Web allows Cross-Domain Search Timing.This issue affects DivvyDrive Web: from 4.8.2.2 before 4.8.2.15.
CVE-2024-41880 1 Veilid 1 Veilid 2026-04-15 5.3 Medium
In veilid-core in Veilid before 0.3.4, the protocol's ping function can be misused in a way that decreases the effectiveness of safety and private routes.
CVE-2023-36325 2026-04-15 3.7 Low
i2p before 2.3.0 (Java) allows de-anonymizing the public IPv4 and IPv6 addresses of i2p hidden services (aka eepsites) via a correlation attack across the IPv4 and IPv6 addresses that occurs when a tunneled, replayed message has a behavior discrepancy (it may be dropped, or may result in a Wrong Destination response). An attack would take days to complete.
CVE-2024-39894 1 Openssh 1 Openssh 2026-04-15 7.5 High
OpenSSH 9.5 through 9.7 before 9.8 sometimes allows timing attacks against echo-off password entry (e.g., for su and Sudo) because of an ObscureKeystrokeTiming logic error. Similarly, other timing attacks against keystroke entry could occur.
CVE-2025-54477 1 Joomla 2 Joomla, Joomla! 2026-04-15 5.3 Medium
Improper handling of authentication requests lead to a user enumeration vector in the passkey authentication method.
CVE-2025-47872 1 Eg4 Electronics 7 Eg4 12000xp, Eg4 12kpv, Eg4 18kpv and 4 more 2026-04-15 5.8 Medium
The public-facing product registration endpoint server responds differently depending on whether the S/N is valid and unregistered, valid but already registered, or does not exist in the database. Combined with the fact that serial numbers are sequentially assigned, this allows an attacker to gain information on the product registration status of different S/Ns.
CVE-2024-40490 1 Sourcebans-pp Project 1 Sourcebans-pp 2026-04-15 7.5 High
An issue in Sourcebans++ before v.1.8.0 allows a remote attacker to obtain sensitive information via a crafted XAJAX call to the Forgot Password function.
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-2025-46804 1 Gnu 1 Screen 2026-04-15 3.3 Low
A minor information leak when running Screen with setuid-root privileges allows unprivileged users to deduce information about a path that would otherwise not be available. Affected are older Screen versions, as well as version 5.0.0.
CVE-2022-50800 1 H3c 1 Ssl Vpn 2026-04-15 7.5 High
H3C SSL VPN contains a user enumeration vulnerability that allows attackers to identify valid usernames through the 'txtUsrName' POST parameter. Attackers can submit different usernames to the login_submit.cgi endpoint and analyze response messages to distinguish between existing and non-existing accounts.
CVE-2025-24391 1 Otrs 1 Otrs 2026-04-15 5.3 Medium
A vulnerability in the External Interface of OTRS allows conclusions to be drawn about the existence of user accounts through different HTTP response codes and messages. This enables an attacker to systematically identify valid email addresses. This issue affects: * OTRS 7.0.X * OTRS 8.0.X * OTRS 2023.X * OTRS 2024.X * OTRS 2025.X
CVE-2024-12663 1 Funnyzpc 1 Mee-admin 2026-04-15 3.7 Low
A vulnerability classified as problematic was found in funnyzpc Mee-Admin up to 1.6. This vulnerability affects unknown code of the file /mee/login of the component Login. The manipulation of the argument username leads to observable response discrepancy. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.
CVE-2020-10369 2026-04-15 5.5 Medium
Certain Cypress (and Broadcom) Wireless Combo chips, when a January 2021 firmware update is not present, allow inferences about memory content via a "Spectra" attack.
CVE-2023-30312 2026-04-15 7.3 High
An issue discovered in OpenWrt 18.06, 19.07, 21.02, 22.03, and beyond allows off-path attackers to hijack TCP sessions, which could lead to a denial of service, impersonating the client to the server (e.g., for access to files over FTP), and impersonating the server to the client (e.g., to deliver false information from a finance website). This occurs because nf_conntrack_tcp_no_window_check is true by default.
