Advisory Summary

CVE-2026-100169 is a HIGH security vulnerability vulnerability (CWE-287: Improper Authentication) affecting Software libraries in the Maven ecosystem. The weakness occurs when when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-100169

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-100169, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Improper Authentication in the social account linking path of the Prowler API in Prowler from 5.4.0 before 5.35.0 allows a remote unauthenticated attacker to obtain persistent access to the account of a user who has not yet registered, because ProwlerSocialAccountAdapter.pre_social_login() in api/src/backend/api/adapters.py links a Google or GitHub login to any existing local account that has the same email address as the one returned by the provider, without requiring that the address has been verified by the provider or on the existing account, and without any other check that both accounts belong to the same person. Self registration is open and the new account is usable at once, because UserViewSet.get_permissions() in api/src/backend/api/v1/views.py grants AllowAny to the create action, ACCOUNT_EMAIL_VERIFICATION is set to none in api/src/backend/config/settings/social_login.py, and the Django ModelBackend checks only the password and is_active, not the django-allauth EmailAddress record. An attacker who registers an email address before its owner keeps the password set at registration after the link is made, because sociallogin.connect() does not reset the password and does not disable the existing account, and the owner who later signs in with Google or GitHub is logged into the attacker's account. django-allauth makes the same email based link on its own, because SOCIALACCOUNT_EMAIL_AUTHENTICATION and SOCIALACCOUNT_EMAIL_AUTHENTICATION_AUTO_CONNECT are both set to True in the same settings module. This gives the attacker the cloud provider credentials, scan findings and tenant memberships held in the account.
