CVE-2026-91973

Vikunja before 2.6.0 is affected by an authentication bypass in its CalDAV BasicAuth endpoints , which lack rate limiting. Remote unauthenticated attackers can issue unbounded credential-guessing requests against the /dav, /.well-known, and /feeds routes, bypassing the instance's anti-brute-force...

CVE-2026-49446

Cosmos provides users the ability self-host a home server by acting as a secure gateway to your application, as well as a server manager. Prior to 0.22.19, tokenMiddleware in src/proxy/routerGen.go can return through the Constellation tunnel bypass before removing x-cosmos-user, x-cosmos-role,...

CVE-2026-55701

The OpenTelemetry Collector Contrib githubreceiver component contains an authentication bypass. Prior to 0.151.0 , the handleReq() function in trace_receiver.go does not enforce the RequiredHeaders configuration on incoming webhook requests—those headers are only validated at startup in config.go...

CVE-2026-55701 OpenTelemetry githubreceiver silently ignores configured required_headers authentication

The OpenTelemetry Collector Contrib repository contains components for the OpenTelemetry Collector. Prior to 0.151.0, the githubreceiver validates the receiver/githubreceiver/config.go RequiredHeaders configuration at startup, but receiver/githubreceiver/tracereceiver.go handleReq does not check...

CVE-2026-49446

Cosmos-Server (a self-hosted secure gateway and server manager by azukaar ) is vulnerable to authentication bypass via forward-auth header smuggling on its Constellation tunnel in versions prior to 0.22.19 . The tokenMiddleware in src/proxy/routerGen.go returns through the Constellation bypass br...

CVE-2026-49446 Cosmos: Authentication bypass via forward-auth header smuggling on Constellation tunnel in Cosmos-Server

Cosmos provides users the ability self-host a home server by acting as a secure gateway to your application, as well as a server manager. Prior to 0.22.19, tokenMiddleware in src/proxy/routerGen.go can return through the Constellation tunnel bypass before removing x-cosmos-user, x-cosmos-role,...

CVE-2026-46495 OpenDJ Pre-Auth RCE via Java Deserialization in JMX RMI

OpenDJ is an LDAPv3 compliant directory service. Prior to 5.1.1, the JMX RMI connector in opendj-server-legacy/src/main/java/org/opends/server/protocols/jmx/RmiConnector.java processes attacker-controlled credential objects before authentication without a restrictive...

EUVD-2026-78573

OpenBMC's IPMI implementation, phosphor-net-ipmid, contains a logic flaw in which an unauthenticated client can force the RAKP Message 1 handler to return before it overwrites the authentication object's constructor defaults. The IPMI service then accepts a RAKP Message 3 whose HMAC is computed...

CVE-2026-16141

OpenBMC's IPMI implementation, phosphor-net-ipmid , contains a logic flaw allowing an unauthenticated client to bypass RAKP authentication. An attacker can force the RAKP Message 1 handler to return before it overwrites the authentication object's constructor defaults, causing the service to acce...

CVE-2026-16140 OpenBMC IPMI Privilege Escalation via Retargeted RAKP 1

OpenBMC's IPMI implementation, phosphor-net-ipmid, is vulnerable to a logic flaw where the authorization context of an existing session can be replaced with a target account while still maintaining the original integrity and encryption keys. Several downstream vendors implement phosphor-net-ipmid...

CVE-2026-92003 MISP Unthrottled Authentication Failure Log Writes Enable Resource Exhaustion

Affected versions of MISP do not consistently apply the existing authentication-failure logging throttle. Two API authentication failure branches wrote directly to the Log model: - API requests with no authentication key; - requests supplying an API key with an incorrect length Unlike other...

CVE-2026-92002

MISP versions ≤2.5.45 use Redis to throttle repeated authentication-failure log entries. The root cause lies in the _shouldLog() method: when User->setupRedis() returns false (i.e., Redis is unreachable), the throttle check suppresses all log writes, effectively silencing authentication-failur...

EUVD-2026-78432

Affected versions of MISP use Redis to throttle repeated authentication-failure log entries. The intent is to avoid excessive duplicate logs while still recording failed authentication activity. However, User-setupRedis returns false when Redis cannot be reached. The vulnerable shouldLog logic on...

CVE-2026-91922

Steedos Platform through 3.0.15-beta.47 contains a reflected cross-site scripting vulnerability in the anonymous /api/page/render endpoint that fails to properly escape query parameters in inline script elements. Attackers can craft malicious links with script-terminating sequences in the schemaA...

CVE-2026-91923

KubeSphere through 4.1.3 contains a server-side request forgery vulnerability in the git credential verification endpoint that accepts unvalidated caller-supplied URLs without allowlist restrictions. Authenticated attackers can supply arbitrary URLs to reach internal services and exfiltrate...

CVE-2026-57134

PraisonAI is a multi-agent teams system. From 1.5.1 until 1.7.2, MCPSecurity.evaluatePolicy in src/praisonai-ts/src/mcp/security.ts invokes the configured credential validator only when AuthMethod is api-key or bearer. Basic and OAuth policies accept any non-empty Authorization header without...
