Advisory Summary

CVE-2026-97764 is a LOW (CVSS 3.7) security vulnerability vulnerability (CWE-180: Incorrect Behavior Order: Validate Before Canonicalize) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product validates input before it is canonicalized, which prevents the product from detecting data that becomes invalid after the canonicalization step.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-97764

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-2026-97764, 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-180: Incorrect Behavior Order: Validate Before Canonicalize, where the product validates input before it is canonicalized, which prevents the product from detecting data that becomes invalid after the canonicalization step. 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

django-allauth before 65.19.4 does not have the expected limits on failed login attempts because, in some common configurations, an attacker can leverage the handling of diacritics (e.g., accents) for a higher effective limit.
