CVE-2004-0294 1 Yabbforumsoftware 1 Yet Another Bulletin Board 2026-04-16 N/A
YaBB 1 SP 1.3.1 displays different error messages when a user exists or not, which makes it easier for remote attackers to identify valid users and conduct a brute force password guessing attack.
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-2024-12663 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-2024-41335 2026-04-15 7.5 High
Draytek devices Vigor 165/166 prior to v4.2.6 , Vigor 2620/LTE200 prior to v3.9.8.8, Vigor 2860/2925 prior to v3.9.7, Vigor 2862/2926 prior to v3.9.9.4, Vigor 2133/2762/2832 prior to v3.9.8, Vigor 2135/2765/2766 prior to v4.4.5.1, Vigor 2865/2866/2927 prior to v4.4.5.3, Vigor 2962/3910 prior to v4.3.2.7, Vigor 3912 prior to v4.3.5.2, and Vigor 2925 up to v3.9.6 were discovered to utilize insecure versions of the functions strcmp and memcmp, allowing attackers to possibly obtain sensitive information via timing attacks.
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-2024-54454 2026-04-15 5.3 Medium
An issue was discovered in Kurmi Provisioning Suite before 7.9.0.35, 7.10.x through 7.10.0.18, and 7.11.x through 7.11.0.15. An Observable Response Discrepancy vulnerability in the sendPasswordReinitLink action of the unlogged.do page allows remote attackers to test whether a username is valid or not. This allows confirmation of valid usernames.
CVE-2023-37482 2026-04-15 5.3 Medium
The login functionality of the web server in affected devices does not normalize the response times of login attempts. An unauthenticated remote attacker could exploit this side-channel information to distinguish between valid and invalid usernames.
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-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-2025-46804 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-2024-54767 2026-04-15 7.5 High
An access control issue in the component /juis_boxinfo.xml of AVM FRITZ!Box 7530 AX v7.59 allows attackers to obtain sensitive information without authentication. NOTE: this is disputed by the Supplier because it cannot be reproduced, and the issue report focuses on an unintended configuration with direct Internet exposure.
CVE-2025-13912 1 Wolfssl 1 Wolfssl 2026-04-15 N/A
Multiple constant-time implementations in wolfSSL before version 5.8.4 may be transformed into non-constant-time binary by LLVM optimizations, which can potentially result in observable timing discrepancies and lead to information disclosure through timing side-channel attacks.
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-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-2024-3296 1 Redhat 1 Enterprise Linux 2026-04-15 5.9 Medium
A timing-based side-channel flaw exists in the rust-openssl package, which could be sufficient to recover a plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages for decryption. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.
CVE-2025-41252 1 Vmware 3 Cloud Foundation, Nsx, Nsx-t 2026-04-15 7.5 High
Description: VMware NSX contains a username enumeration vulnerability. An unauthenticated malicious actor may exploit this to enumerate valid usernames, potentially leading to unauthorized access attempts. Impact: Username enumeration → facilitates unauthorized access. Attack Vector: Remote, unauthenticated. Severity: Important. CVSSv3: 7.5 (High). Acknowledgments: Reported by the National Security Agency. Affected Products: * VMware NSX 9.x.x.x, 4.2.x, 4.1.x, 4.0.x * NSX-T 3.x * VMware Cloud Foundation (with NSX) 5.x, 4.5.x Fixed Versions:  * NSX 9.0.1.0; 4.2.2.2/4.2.3.1 http://4.2.2.2/4.2.3.1 ; 4.1.2.7; NSX-T 3.2.4.3; CCF async patch (KB88287). Workarounds: None.
CVE-2021-47664 2026-04-15 5.3 Medium
Due to improper authentication mechanism an unauthenticated remote attacker can enumerate valid usernames.
CVE-2024-47057 1 Mautic 1 Mautic 2026-04-15 5.3 Medium
SummaryThis advisory addresses a security vulnerability in Mautic related to the "Forget your password" functionality. This vulnerability could be exploited by unauthenticated users to enumerate valid usernames. User Enumeration via Timing Attack: A user enumeration vulnerability exists in the "Forget your password" functionality. Differences in response times for existing and non-existing users, combined with a lack of request limiting, allow an attacker to determine the existence of usernames through a timing-based attack. MitigationPlease update to a version that addresses this timing vulnerability, where password reset responses are normalized to respond at the same time regardless of user existence.
CVE-2025-6386 1 Parisneo 1 Lollms 2026-04-15 N/A
The parisneo/lollms repository is affected by a timing attack vulnerability in the `authenticate_user` function within the `lollms_authentication.py` file. This vulnerability allows attackers to enumerate valid usernames and guess passwords incrementally by analyzing response time differences. The affected version is the latest, and the issue is resolved in version 20.1. The vulnerability arises from the use of Python's default string equality operator for password comparison, which compares characters sequentially and exits on the first mismatch, leading to variable response times based on the number of matching initial characters.
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.
