| CVE-2026-26158 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Hummingbird | 2026-04-03 | 7 High |
| A flaw was found in BusyBox. This vulnerability allows an attacker to modify files outside of the intended extraction directory by crafting a malicious tar archive containing unvalidated hardlink or symlink entries. If the tar archive is extracted with elevated privileges, this flaw can lead to privilege escalation, enabling an attacker to gain unauthorized access to critical system files. | ||||
| CVE-2026-26157 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Hummingbird | 2026-04-03 | 7 High |
| A flaw was found in BusyBox. Incomplete path sanitization in its archive extraction utilities allows an attacker to craft malicious archives that when extracted, and under specific conditions, may write to files outside the intended directory. This can lead to arbitrary file overwrite, potentially enabling code execution through the modification of sensitive system files. | ||||
| CVE-2026-34820 | 1 Endian | 1 Firewall | 2026-04-03 | 6.4 Medium |
| Endian Firewall version 3.3.25 and prior allow stored cross-site scripting (XSS) via the remark parameter to /manage/ipsec/. An authenticated attacker can inject arbitrary JavaScript that is stored and executed when other users view the affected page. | ||||
| CVE-2026-33544 | 1 Steveiliop56 | 1 Tinyauth | 2026-04-03 | 7.7 High |
| Tinyauth is an authentication and authorization server. Prior to version 5.0.5, all three OAuth service implementations (GenericOAuthService, GithubOAuthService, GoogleOAuthService) store PKCE verifiers and access tokens as mutable struct fields on singleton instances shared across all concurrent requests. When two users initiate OAuth login for the same provider concurrently, a race condition between VerifyCode() and Userinfo() causes one user to receive a session with the other user's identity. This issue has been patched in version 5.0.5. | ||||
| CVE-2026-34826 | 1 Rack | 1 Rack | 2026-04-03 | 5.3 Medium |
| Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Utils.get_byte_ranges parses the HTTP Range header without limiting the number of individual byte ranges. Although the existing fix for CVE-2024-26141 rejects ranges whose total byte coverage exceeds the file size, it does not restrict the count of ranges. An attacker can supply many small overlapping ranges such as 0-0,0-0,0-0,... to trigger disproportionate CPU, memory, I/O, and bandwidth consumption per request. This results in a denial of service condition in Rack file-serving paths that process multipart byte range responses. This issue has been patched in versions 2.2.23, 3.1.21, and 3.2.6. | ||||
| CVE-2026-34827 | 1 Rack | 1 Rack | 2026-04-03 | 7.5 High |
| Rack is a modular Ruby web server interface. From versions 3.0.0.beta1 to before 3.1.21, and 3.2.0 to before 3.2.6, Rack::Multipart::Parser#handle_mime_head parses quoted multipart parameters such as Content-Disposition: form-data; name="..." using repeated String#index searches combined with String#slice! prefix deletion. For escape-heavy quoted values, this causes super-linear processing. An unauthenticated attacker can send a crafted multipart/form-data request containing many parts with long backslash-escaped parameter values to trigger excessive CPU usage during multipart parsing. This results in a denial of service condition in Rack applications that accept multipart form data. This issue has been patched in versions 3.1.21 and 3.2.6. | ||||
| CVE-2026-26962 | 1 Rack | 1 Rack | 2026-04-03 | 4.8 Medium |
| Rack is a modular Ruby web server interface. From version 3.2.0 to before version 3.2.6, Rack::Multipart::Parser unfolds folded multipart part headers incorrectly. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values such as filename or name instead of removing the folded line break during unfolding. As a result, applications that later reuse those parsed values in HTTP response headers may be vulnerable to downstream header injection or response splitting. This issue has been patched in version 3.2.6. | ||||
| CVE-2026-5370 | 1 Krayin | 1 Laravel-crm | 2026-04-03 | 3.5 Low |
| A vulnerability was identified in krayin laravel-crm up to 2.2. Impacted is the function composeMail of the file packages/Webkul/Admin/tests/e2e-pw/tests/mail/inbox.spec.ts of the component Activities Module/Notes Module. The manipulation leads to cross site scripting. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. The identifier of the patch is 73ed28d466bf14787fdb86a120c656a4af270153. To fix this issue, it is recommended to deploy a patch. | ||||
| CVE-2026-34834 | 1 Bulwarkmail | 1 Webmail | 2026-04-03 | N/A |
| Bulwark Webmail is a self-hosted webmail client for Stalwart Mail Server. Prior to version 1.4.10, the verifyIdentity() function contained logic that returned true if no session cookies were present. This allowed unauthenticated attackers to bypass security checks and access/modify user settings via the /api/settings endpoint by providing arbitrary headers. This issue has been patched in version 1.4.10. | ||||
| CVE-2026-34831 | 1 Rack | 1 Rack | 2026-04-03 | 4.8 Medium |
| Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Files#fail sets the Content-Length response header using String#size instead of String#bytesize. When the response body contains multibyte UTF-8 characters, the declared Content-Length is smaller than the number of bytes actually sent on the wire. Because Rack::Files reflects the requested path in 404 responses, an attacker can trigger this mismatch by requesting a non-existent path containing percent-encoded UTF-8 characters. This results in incorrect HTTP response framing and may cause response desynchronization in deployments that rely on the incorrect Content-Length value. This issue has been patched in versions 2.2.23, 3.1.21, and 3.2.6. | ||||
| CVE-2026-34828 | 1 Nadh | 1 Listmonk | 2026-04-03 | 7.1 High |
| listmonk is a standalone, self-hosted, newsletter and mailing list manager. From version 4.1.0 to before version 6.1.0, a session management vulnerability allows previously issued authenticated sessions to remain valid after sensitive account security changes, specifically password reset and password change. As a result, an attacker who has already obtained a valid session cookie can retain access to the account even after the victim changes or resets their password. This weakens account recovery and session security guarantees. This issue has been patched in version 6.1.0. | ||||
| CVE-2026-34610 | 1 Smuellerdd | 1 Leancrypto | 2026-04-03 | 5.9 Medium |
| The leancrypto library is a cryptographic library that exclusively contains only PQC-resistant cryptographic algorithms. Prior to version 1.7.1, lc_x509_extract_name_segment() casts size_t vlen to uint8_t when storing the Common Name (CN) length. An attacker who crafts a certificate with CN = victim's CN + 256 bytes padding gets cn_size = (uint8_t)(256 + N) = N, where N is the victim's CN length. The first N bytes of the attacker's CN are the victim's identity. After parsing, the attacker's certificate has an identical CN to the victim's — enabling identity impersonation in PKCS#7 verification, certificate chain matching, and code signing. This issue has been patched in version 1.7.1. | ||||
| CVE-2026-4634 | 1 Redhat | 1 Build Keycloak | 2026-04-03 | 7.5 High |
| A flaw was found in Keycloak. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted POST request with an excessively long scope parameter to the OpenID Connect (OIDC) token endpoint. This leads to high resource consumption and prolonged processing times, ultimately resulting in a Denial of Service (DoS) for the Keycloak server. | ||||
| CVE-2026-33617 | 1 Mbconnectline | 2 Mbconnect24, Mymbconnect24 | 2026-04-03 | 5.3 Medium |
| An unauthenticated remote attacker can access a configuration file containing database credentials. This can result in a some loss of confidentiality, but there is no endpoint exposed to use these credentials. | ||||
| CVE-2024-42040 | 1 Denx | 1 U-boot | 2026-04-03 | 8.1 High |
| Buffer Overflow vulnerability in the net/bootp.c in DENEX U-Boot from its initial commit in 2002 (3861aa5) up to today on any platform allows an attacker on the local network to leak memory from four up to 32 bytes of memory stored behind the packet to the network depending on the later use of DHCP-provided parameters via crafted DHCP responses. | ||||
| CVE-2026-34400 | 1 Alerta | 1 Alerta | 2026-04-03 | 9.8 Critical |
| Alerta is a monitoring tool. Prior to version 9.1.0, the Query string search API (q=) was vulnerable to SQL injection via the Postgres query parser, which built WHERE clauses by interpolating user-supplied search terms directly into SQL strings via f-strings. This issue has been patched in version 9.1.0. | ||||
| CVE-2026-34215 | 2 Parse Community, Parseplatform | 2 Parse Server, Parse-server | 2026-04-03 | 6.5 Medium |
| Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.63 and 9.7.0-alpha.7, the verify password endpoint returns unsanitized authentication data, including MFA TOTP secrets, recovery codes, and OAuth access tokens. An attacker who knows a user's password can extract the MFA secret to generate valid MFA codes, defeating multi-factor authentication protection. This issue has been patched in versions 8.6.63 and 9.7.0-alpha.7. | ||||
| CVE-2026-33415 | 1 Discourse | 1 Discourse | 2026-04-03 | 4.3 Medium |
| Discourse is an open-source discussion platform. From versions 2026.1.0-latest to before 2026.1.3, 2026.2.0-latest to before 2026.2.2, and 2026.3.0-latest to before 2026.3.0, an authenticated moderator-level user could retrieve post content, topic titles, and usernames from categories they were not authorized to view. Insufficient access controls on a sentiment analytics endpoint allowed category permission boundaries to be bypassed. This issue has been patched in versions 2026.1.3, 2026.2.2, and 2026.3.0. | ||||
