tomcat: Apache Tomcat: Improper Authentication due to principal lookup failure

A flaw was found in Apache Tomcat. This improper authentication vulnerability allows a remote attacker to be authenticated even if their user account does not exist in the DataSourceRealm, under specific circumstances such as CLIENT-CERT or SPNEGO authentication. This can lead to unauthorized...

tomcat: Apache Tomcat: Authentication bypass via limited replay attack in DIGEST authenticator

A flaw was found in Apache Tomcat. This vulnerability, an authentication bypass by capture-replay, affects the DIGEST authenticator. A remote attacker can exploit this by making a specially crafted DIGEST authenticated request with a nonceCount at the upper boundary of the replay window. This...

tomcat: Apache Tomcat: Unauthorized resource access via FORM authentication bypass

A flaw was found in Apache Tomcat. This incorrect authorization vulnerability occurs within the FORM authentication process, allowing a user to bypass security constraints. This bypass enables unauthorized access to resources via a GET request, even when those resources are intended to be...

httpd: httpd: Authentication state corruption via concurrent Digest authentication requests

A flaw was found in httpd's modauthdigest module. A use-after-free vulnerability allows an unauthenticated remote attacker to corrupt the server's authentication state by submitting concurrent Digest authentication requests. This issue occurs when specific configuration settings, such as nonce...

httpd: mod_auth_digest: timing attack allows a bypass of digest authentication

A flaw was found in the modauthdigest module of httpd. A remote unauthenticated attacker can bypass digest authentication by measuring timing discrepancies of requests. This issue leads to unauthorized access to resources protected by digest authentication...

httpd: httpd: Authentication bypass via credential replay in mod_auth_digest

A flaw was found in the modauthdigest module of the Apache HTTP Server. This vulnerability allows an attacker positioned on the network to bypass authentication by replaying previously intercepted user credentials. When the server is configured with a nonce a single-use security token lifetime of...

CVE-2026-119278

Versions 3.0.0 through 3.3.7 and 3.4.5 of MariaDB Connector/J are vulnerable to a denial-of-service condition during caching_sha2_password authentication. The root cause is the improper handling of the authentication-more-data response, where the driver treats it as a length-encoded byte array an...

CVE-2026-119278 MariaDB Connector/J: Rogue server can crash the client during caching_sha2_password authentication

MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From 3.0.0 until 3.3.7 and 3.4.5, during cachingsha2password authentication, the authentication-more-data response was treated as a length-encoded byte array, memory was allocated from the...
