authentik is an open-source identity provider. When initialising a oauth2 flow with a `code_challenge` and `code_method` (thus requesting PKCE), the single sign-on provider (authentik) must check if there is a matching and existing `code_verifier` during the token step. Prior to versions 2023.10.4 and 2023.8.5, authentik checks if the contents of `code_verifier` is matching only when it is provided. When it is left out completely, authentik simply accepts the token request with out it; even when the flow was started with a `code_challenge`. authentik 2023.8.5 and 2023.10.4 fix this issue.

After the initial setup process, some steps of setup.php file are reachable not only by super-administrators, but by unauthenticated users as well. Malicious actor can pass step checks and potentially change the configuration of Zabbix Frontend.

RobotsAndPencils go-saml, a SAML client library written in Go, contains an authentication bypass vulnerability in all known versions. This is due to how the `xmlsec1` command line tool is called internally to verify the signature of SAML assertions. When `xmlsec1` is used without defining the enabled key data, the origin of the public key for the signature verification is, unfortunately, not restricted. That means an attacker can sign the SAML assertions themselves and provide the required public key (e.g. an RSA key) directly embedded in the SAML token. Projects still using RobotsAndPencils/go-saml should move to another SAML library or alternatively remove support for SAML from their projects. The vulnerability can likely temporarily be fixed by forking the go-saml project and adding the command line argument `--enabled-key-data` and specifying a value such as `x509` or `raw-x509-cert` when calling the `xmlsec1` binary in the verify function. Please note that this workaround must be carefully tested before it can be used.

CreateWiki is Miraheze's MediaWiki extension for requesting & creating wikis. Without the patch for this issue, anonymous comments can be made using Special:RequestWikiQueue when sent directly via POST. A patch for this issue is available in the `master` branch of CreateWiki's GitHub repository.

In IQrouter through 3.3.1, the Lua function diag_set_password in the web-panel allows remote attackers to change the root password arbitrarily. Note: The vendor claims that this vulnerability can only occur on a brand-new network that, after initiating the forced initial configuration (which has a required step for setting a secure password on the system), makes this CVE invalid. This vulnerability is “true for any unconfigured release of OpenWRT, and true of many other new Linux distros prior to being configured for the first time”

In SonarQube 8.4.2.36762, an external attacker can achieve authentication bypass through SonarScanner. With an empty value for the -D sonar.login option, anonymous authentication is forced. This allows creating and overwriting public and private projects via the /api/ce/submit endpoint.

The wpo365-login plugin before v11.7 for WordPress allows use of a symmetric algorithm to decrypt a JWT token. This leads to authentication bypass.

The affected versions are before version 8.19.1.

The web interface of the 1734-AENTR communication module mishandles authentication for HTTP POST requests. A remote, unauthenticated attacker can send a crafted request that may allow for modification of the configuration settings.

Soft Serve is a self-hostable Git server for the command line. Prior to version 0.6.2, a security vulnerability in Soft Serve could allow an unauthenticated, remote attacker to bypass public key authentication when keyboard-interactive SSH authentication is active, through the `allow-keyless` setting, and the public key requires additional client-side verification for example using FIDO2 or GPG. This is due to insufficient validation procedures of the public key step during SSH request handshake, granting unauthorized access if the keyboard-interaction mode is utilized. An attacker could exploit this vulnerability by presenting manipulated SSH requests using keyboard-interactive authentication mode. This could potentially result in unauthorized access to the Soft Serve. Users should upgrade to the latest Soft Serve version `v0.6.2` to receive the patch for this issue. To workaround this vulnerability without upgrading, users can temporarily disable Keyboard-Interactive SSH Authentication using the `allow-keyless` setting.

CloudExplorer Lite is an open source, lightweight cloud management platform. Prior to version 1.4.1, the gateway filter of CloudExplorer Lite uses a controller with path starting with `matching/API/`, which can cause a permission bypass. Version 1.4.1 contains a patch for this issue.

The affected versions are before version 8.19.1.

The encryption functionality in the Virtual Supervisor Module (VSM) to Virtual Ethernet Module (VEM) communication component in Cisco NX-OS on the Nexus 1000V does not properly authenticate VSM/VEM packets, which allows remote attackers to disable packet-level encryption and integrity protection via crafted packets, aka Bug ID CSCud14710.

Mozilla Firefox before 2.0.0.13 and SeaMonkey before 1.1.9, when generating the HTTP Referer header, does not list the entire URL when it contains Basic Authentication credentials without a username, which makes it easier for remote attackers to bypass application protection mechanisms that rely on Referer headers, such as with some Cross-Site Request Forgery (CSRF) mechanisms.

Cisco NX-OS on the Nexus 1000V does not properly handle authentication for Virtual Ethernet Module (VEM) to Virtual Supervisor Module (VSM) communication, which allows remote attackers to obtain VEM access via (1) spoofed STUN packets or (2) a crafted VMware ESXi instance, aka Bug ID CSCud14832.

The "OpenID Connect Relying Party and OAuth 2.0 Resource Server" (aka mod_auth_openidc) module before 2.1.5 for the Apache HTTP Server does not skip OIDC_CLAIM_ and OIDCAuthNHeader headers in an "OIDCUnAuthAction pass" configuration, which allows remote attackers to bypass authentication via crafted HTTP traffic.

IBM WebSphere Message Broker 6.1 before 6.1.0.12, 7.0 before 7.0.0.6, and 8.0 before 8.0.0.2 does not validate Basic Authentication credentials before proceeding to WS-Addressing and WS-Security operations, which allows remote attackers to trigger transmission of unauthenticated messages via unspecified vectors.

The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 caches information about the authenticated user within the session state, which makes it easier for remote attackers to bypass authentication via vectors related to the session ID.
