### Summary IdTokenClaimsValidator skips `aud` claim validation if token is issued by same identity issuer/provider. ### Details See https://github.com/micronaut-projects/micronaut-security/blob/master/security-oauth2/src/main/java/io/micronaut/security/oauth2/client/IdTokenClaimsValidator.java#L202 This logic violates point 3 of https://openid.net/specs/openid-connect-core-1_0.html#IDTokenValidation. Workaround exists by setting `micronaut.security.token.jwt.claims-validators.audience` with valid values. `micronaut.security.token.jwt.claims-validators.openid-idtoken` can be kept as default on. ### PoC Should probably be: ```java return issuer.equalsIgnoreCase(iss) && audiences.contains(clientId) && validateAzp(claims, clientId, audiences); ``` ### Impact Any OIDC setup using Micronaut where multiple OIDC applications exists for the same issuer but token auth are not meant to be shared.

A content spoofing flaw was found in OpenShift's OAuth endpoint. This flaw allows a remote, unauthenticated attacker to inject text into a webpage, enabling the obfuscation of a phishing operation.

A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients.

A software company sold a New Jersey police department an algorithm that was right less than 1 percent of the time.

LUCR-3 targets Fortune 2000 companies across various sectors, including but not limited to Software, Retail, Hospitality,

A Server-Side Request Forgery issue in the OpenID Connect Issuer in LemonLDAP::NG before 2.17.1 allows authenticated remote attackers to send GET requests to arbitrary URLs through the request_uri authorization parameter. This is similar to CVE-2020-10770.

A civil liberties group has asked the DOJ to investigate deployment of the ShotSpotter gunfire-detection system, which research shows is often installed in predominantly Black neighborhoods.

The Staff / Employee Business Directory for Active Directory plugin for WordPress is vulnerable to LDAP Passback in versions up to, and including, 1.2.3. This is due to insufficient validation when changing the LDAP server. This makes it possible for authenticated attackers, with administrative access and above, to change the LDAP server and retrieve the credentials for the original LDAP server.

A reflected cross-site scripting (XSS) vulnerability was found in the 'oob' OAuth endpoint due to incorrect null-byte handling. This issue allows a malicious link to insert an arbitrary URI into a Keycloak error page. This flaw requires a user or administrator to interact with a link in order to be vulnerable. This may compromise user details, allowing it to be changed or collected by an attacker.

Corporations are using software to monitor employees on a large scale. Some experts fear the data these tools collect could be used to automate people out of their jobs.
