CVE-2019-3822 [CRITICAL] CWE-121 CVE-2019-3822: libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The f libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting ov

CVE-2026-28368 [CRITICAL] CWE-444 CVE-2026-28368: A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially cra A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially crafted requests where header names are parsed differently by Undertow compared to upstream proxies. This discrepancy in header interpretation can be exploited to launch request smuggling attacks, potentially bypassing security controls and accessing u

CVE-2026-28369 [CRITICAL] CWE-444 CVE-2026-28369: A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line sta A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attack

CVE-2020-27846 [CRITICAL] CWE-115 CVE-2020-27846: A signature verification vulnerability exists in crewjam/saml. This flaw allows an attacker to bypas A signature verification vulnerability exists in crewjam/saml. This flaw allows an attacker to bypass SAML Authentication. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

CVE-2019-3816 [HIGH] CWE-22 CVE-2019-3816: Openwsman, versions up to and including 2.6.9, are vulnerable to arbitrary file disclosure because t Openwsman, versions up to and including 2.6.9, are vulnerable to arbitrary file disclosure because the working directory of openwsmand daemon was set to root directory. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted HTTP request to openwsman server.

CVE-2026-21710 [HIGH] CWE-770 CVE-2026-21710: A flaw in Node.js HTTP request handling causes an uncaught `TypeError` when a request is received wi A flaw in Node.js HTTP request handling causes an uncaught `TypeError` when a request is received with a header named `__proto__` and the application accesses `req.headersDistinct`. When this occurs, `dest["__proto__"]` resolves to `Object.prototype` rather than `undefined`, causing `.push()` to be called on a non-array. This exception is thrown sync

CVE-2018-14618 [CRITICAL] CVE-2018-14618: curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The in curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate outpu

CVE-2016-0639 [CRITICAL] CVE-2016-0639: Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier and 5.7.11 and earlier allows remote at Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier and 5.7.11 and earlier allows remote attackers to affect confidentiality, integrity, and availability via vectors related to Pluggable Authentication.

CVE-2019-10192 [HIGH] CWE-122 CVE-2019-10192: A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By carefully corrupting a hyperloglog using the SETRANGE command, an attacker could trick Redis interpretation of dense HLL encoding to write up to 3 bytes beyond the end of a heap-allocated buffer.
