fwknop

fwknop - 单包授权 Single Packet Authorization 简介 fwknop 实现了一种称为单包授权 SPA 的授权方案，用于强大的服务隐藏。SPA 只要求一个数据包，该数据包经过加密、不可重放，并通过 HMAC 进行身份验证，以便向隐藏在默认丢弃过滤规则的防火墙后面的服务传达所需的访问权限。SPA 的主要应用是使用防火墙丢弃所有尝试连接到 SSH 等服务的行为，从而使利用漏洞（包括 0-day 和未打补丁的代码）更加困难。由于没有开放端口，任何通过 SPA 隐藏的服务自然无法被 Nmap 扫描到。fwknop 项目支持四种不同的防火墙：Linux 上的...

CVE-2026-100834

The http4k library's Digest authentication module (org.http4k:http4k-security-digest ) is vulnerable in versions before 6.48.0.0 , 5.42.0.0 , and 4.51.0.0 . The root cause is that the nonceVerifier parameter in ServerFilters.DigestAuth and DigestAuthProvider defaults to { true }, meaning every no...

CVE-2026-100834 http4k before 6.48.0.0 Digest Authentication Replay Protection Bypass

http4k's Digest authentication module org.http4k:http4k-security-digest before versions 6.48.0.0, 5.42.0.0 and 4.51.0.0 defaults the nonceVerifier parameter of ServerFilters.DigestAuth and DigestAuthProvider to true , so every nonce is accepted regardless of its value, age, or prior use...

CVE-2026-90997

Keycloak deployments in stateless mode with MySQL or MariaDB are affected by a replay protection bypass caused by a mismatch in row-count semantics between the database driver and Keycloak's application logic. An attacker who intercepts single-use security artifacts—such as JWT client assertions ...

CVE-2026-90997 Keycloak-services: keycloak: replay protection bypass leads to unauthorized access via database driver semantics mismatch

A flaw was found in Keycloak. When deployed in stateless mode with MySQL or MariaDB, a mismatch in row-count semantics between the database driver and Keycloak's application logic allows an attacker to bypass replay protection. This vulnerability enables an attacker who intercepts single-use...

EUVD-2026-79236

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, DigestAuth replay protection records lastNc plus one instead of the highest nonce-count value it has accepted. When a legitimate client sends noncontiguous nc values because of parallel or retried requests, the stored...

CVE-2026-12704

When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and ga...

PT-2026-76559

Name of the Vulnerable Software and Affected Versions Nimiq versions prior to 1.5.1 Description The validity store uses a strict lower-bound comparison that expires stored transactions too early relative to the Transaction::is valid at function. This occurs because the store treats a transaction...

Insufficient Verification of Data Authenticity

Overview org.apache.cxf:cxf-rt-rs-security-oauth2 is a services framework. Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the JwtRequestCodeFilter process. An attacker can override security-sensitive parameters such as codechallenge,...

CVE-2026-63687

A security bypass vulnerability exists in Apache CXF within the cxf-rt-rs-security-oauth2 component. The JwtRequestCodeFilter fails to exclude security-sensitive parameters when copying claims from a signed request JWT into the authorization parameter map. An attacker who possesses or compromises...
