CVE-2026-53661 Vulnerability Summary

CVE-2026-53661: Boruta is a standalone authorization server that aims to implement OAuth 2.0 and Openid Connect up to decentralized identity specifications. Prior to version 0.9.1, boruta session cookies and the identity “remember me” cookie were set without the Secure attribute. In deployments where users could reach the same Boruta origin over plaintext HTTP, browsers could send these cookies over an unencrypted connection. An attacker able to observe or intercept that network traffic could recover a valid session or remember-me cookie and reuse it to impersonate the affected user. Affected components include boruta_web, boruta_identity, and boruta_admin. The affected cookies include the shared session cookie, defaulting to _boruta_web_key, and the identity remember-me cookie, defaulting to `_boruta_identity_web_user_remember_me`. The issue is fixed in commit 18691c655164635066aa113003a3cd87f6ed11cd, released as part of version 0.9.1. The patch sets `secure: true` and `same_site: "Lax"` on configured session cookies for boruta_web, boruta_identity, and boruta_admin, and sets `secure: true` on the identity remember-me cookie. Until upgrading to a release containing the fix: terminate or reject plaintext HTTP before requests reach Boruta; enforce HTTPS-only access at the reverse proxy or load balancer; enable HSTS for Boruta domains; if cookie exposure is suspected, rotate SECRET_KEY_BASE and BORUTA_SESSION_COOKIE_SIGNING_SALT, then require users to authenticate again. Upgrade to a version containing commit 18691c655164635066aa113003a3cd87f6ed11cd, or apply the patch manually. After deploying the fix, verify that Boruta session and remember-me cookies include the Secure attribute in browser developer tools or with an HTTP response inspection tool.

Assessing the Risk of CVE-2026-53661

Access Complexity Graph

The exploitability of CVE-2026-53661 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-53661

No exploitability data is available for CVE-2026-53661.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-53661, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CWE-614

CAPEC Common Attack Pattern Enumeration and Classification

  • Session Sidejacking CAPEC-102 Session sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.
