CWE-384 vulnerabilities

CVE-2026-61592 is a session fixation vulnerability in djust versions prior to 1.0.7. The issue arises because SSE sessions were keyed solely by a client-chosen session_id without binding to the authenticated user, allowing an attacker who obtains a valid session_id to impersonate the victim. This vulnerability is fixed in version 1.0.7 by binding SSE sessions to the owning principal and rejecting cross-principal access. A workaround is to disable the SSE transport.

Session fixation vulnerability in Secomea GateManager (webserver module) allows Session Fixation. This issue affects GateManager: 11.5;0, 11.4.625515072:0. Fixed in Version 11.6 or 11.4.626194074 and above

tirreno, a security framework, has a session fixation issue in versions prior to 0.10.0. During authentication, tirreno validates the user's credentials and establishes the authenticated session, but it does not call `session_regenerate_id()` afterward. As a result, the session identifier is not rotated on login, it stays the same before and after authentication. An attacker able to fix a known session identifier in a victim's browser (for example through a network man-in-the-middle position, or a separate cross-site scripting or subdomain cookie-injection issue) could then gain access to the victim's authenticated session. The issue is fixed in v0.10.0. The session identifier is now regenerated on successful authentication, and the previous session is destroyed. There is no configuration-level workaround.

Adobe Photoshop Mobile for Android contains a session fixation vulnerability that could allow an attacker to escalate privileges by exploiting a victim's interaction with a malicious webpage. The vulnerability affects versions up to 1.6.0.2299 and requires user interaction. The scope of the vulnerability is changed, indicating a potential impact beyond the initially affected component.

CVE-2026-18527 is a critical session fixation vulnerability in IBM Administration Runtime Expert for i version 1R1M0. It allows an unauthenticated remote attacker to execute actions under another user's authenticated profile, resulting in elevated privileges on the IBM i system. The vulnerability arises from the ARE GUI component processing. No patch or official remediation has been confirmed yet.

Ghost, a Node.js content management system, had a session fixation vulnerability in its Admin interface from versions 2.2.0 up to but not including 6.54.1. The issue allowed existing sessions to remain valid upon login, potentially enabling session fixation attacks if combined with another vulnerability on the same domain. This vulnerability was fixed in version 6.54.1.

The terraform-mcp-server before version 1.1.0 is vulnerable to an authorization bypass in the streamable-HTTP stateful transport mode that may allow a user who obtains another user's MCP session ID to have their tool calls executed using that user's Terraform credentials. This vulnerability, CVE-2026-16496, is fixed in terraform-mcp-server 1.1.0.

A flaw was found in the keycloak-services component of Red Hat Build of Keycloak. The issue occurs because OAuth 2.0 authorization codes are not properly bound to the client that originally requested them. An attacker who can intercept an authorization code can modify it to be redeemed by their own client, potentially allowing them to obtain access tokens for a victim's identity.

Session fixation vulnerability in Wikimedia Foundation OAuth. This vulnerability is associated with program files src/Backend/MWOAuthServer.Php. This issue affects OAuth: from * through 1.46.0, 1.45.4, 1.44.6, 1.43.9.

KTM System e-BOK allows the session identifier to be set by the client prior to authentication. If a cookie with a valid name is set, its value remains unchanged after successful login. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session. This issue was fixed in the patch published in June 2026.

EasyFlow .NET developed by Digiwin has a Session Fixation vulnerability. If unauthenticated remote attackers replace a specific session ID for a user, they can gain the user's privilege once the user logs in.

A WebFlux application with a compromised subdomain (for example, compromised via cross-site scripting (XSS)) is vulnerable to an escalation attack exchanging a known session ID for that of an authenticated user. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.

QuickCMS allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session. This issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.

Apache Shiro versions 1.0, 3.0.0-alpha, and up to 2.1.0 have a session fixation vulnerability in their default configurations. The issue occurs because existing sessions are not invalidated nor replaced with new session IDs upon successful login. This vulnerability allows an attacker to fixate a user's session ID, potentially leading to unauthorized session use. The vulnerability is fixed in Apache Shiro versions 2.1.1 and 3.0.0-alpha-2 or later.

A Cross-Site Request Forgery (CSRF) vulnerability exists in vercel turborepo versions prior to 2.9.14. The issue occurs in the self-hosted login and SSO browser flows where the CSRF state value on the localhost callback was not validated. This allows a malicious web page to send a request with an attacker-controlled token to the local callback server, potentially causing the CLI to complete login with incorrect credentials. Vercel-hosted login flows using device authorization are not affected. The vulnerability is fixed in version 2.9.14.

Session fixation in Visual Studio Code allows an unauthorized attacker to elevate privileges over a network.

CVE-2026-30808 is a session fixation vulnerability in Pandora FMS versions 777 through 800 that allows an attacker to hijack user sessions by using a crafted session ID. The vulnerability has a high severity with a CVSS score of 7.6. It requires user interaction and can lead to unauthorized access to user sessions.

Dell PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release versions 8.4 through 8.5 contain a session fixation vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access.

Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, in main/lp/aicc_hacp.php, user-controlled request parameters are directly used to set the PHP session ID before loading global bootstrap. This leads to session fixation. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.

MCP Ruby SDK is the official Ruby SDK for Model Context Protocol servers and clients. Prior to version 0.9.2, the Ruby SDK's streamable_http_transport.rb implementation contains a session hijacking vulnerability. An attacker who obtains a valid session ID can completely hijack the victim's Server-Sent Events (SSE) stream and intercept all real-time data. Version 0.9.2 contains a patch.
