CVE-2026-43828: CWE-614 Sensitive Cookie in HTTPS Session Without 'Secure' Attribute in Apache Software Foundation Apache Shiro
Apache Shiro versions 1.0 through 2.1.0 and 3.0.0-alpha-1 have a vulnerability where sensitive cookies (JSESSIONID and rememberMe) used in HTTPS sessions are sent without the 'Secure' attribute by default. This omission can expose these cookies to interception over non-secure channels. The issue is fixed in versions 2.1.1 and 3.0.0-alpha-2 or later.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-43828 affects Apache Shiro from version 1.0 up to but not including 2.1.1, and version 3.0.0-alpha-1. The default configuration of Apache Shiro's native session manager and Remember-Me manager sends the JSESSIONID and rememberMe cookies without the 'Secure' attribute in HTTPS sessions. The absence of the 'Secure' attribute means these cookies could be transmitted over unencrypted HTTP connections, potentially exposing sensitive session information. Upgrading to Apache Shiro version 2.1.1 or 3.0.0-alpha-2 or later addresses this issue by ensuring the 'Secure' attribute is set on these cookies.
Potential Impact
Sensitive session cookies (JSESSIONID and rememberMe) may be transmitted without the 'Secure' flag, increasing the risk of interception over non-HTTPS connections. This could lead to session hijacking or unauthorized access if an attacker can capture these cookies. The CVSS 4.0 score is 5.9 (medium severity), reflecting the network attack vector, low complexity, partial attack requirements, and user interaction needed.
Mitigation Recommendations
Users should upgrade Apache Shiro to version 2.1.1 or later, or 3.0.0-alpha-2 or later, where this issue is fixed by default. No other vendor advisory or patch information is provided, so patching to the fixed versions is the recommended remediation. Patch status is confirmed by the vendor advisory stating the fixed versions.
