Session Hijacking

Multiple critical vulnerabilities in Bilin Software and Informatics Consultancy Inc. HUMANIST Digital Human Resources version 26.0 allow unauthorized access, web shell upload, session hijacking, and remote code execution. Upgrade to version 26.1 immediately.

The Ruby SDK for the Model Context Protocol (MCP) lacks session ownership validation, allowing attackers to perform unauthorized tool executions within a victim's active session.

Multiple vulnerabilities in OmniFaces versions prior to 1.14.3, 2.7.33, 3.14.23, 4.7.12, and 5.4.2 allow attackers to exploit forged combined-resource IDs leading to server-side request forgery (SSRF)-like behavior or information disclosure, achieve client-side arbitrary code execution via cross-site scripting (XSS) in `o:hashParam`, bypass session authentication for push channels resulting in unauthorized message interception, and cause denial-of-service (DoS) via unbounded caches.

An authenticated low-privilege user can exploit CVE-2026-59216 in Open WebUI versions prior to 0.10.0 to execute arbitrary Python code or tools within another user's authenticated session by supplying an unvalidated `session_id`, which, if targeting an administrator, leads to remote code execution on the server as the root process.

SurrealDB versions prior to 3.1.0 are vulnerable to a session hijacking flaw (CVE-2026-63757) where unauthenticated attackers can enumerate session UUIDs via the HTTP /rpc sessions method and impersonate authenticated sessions to read, write, and delete data, leading to privilege escalation.

A vulnerability, CVE-2026-9323, in the urwid web display backend (urwid/display/web.py) allows attackers to predict and hijack web session identifiers ('urwid_id') due to the use of a non-cryptographically secure pseudo-random number generator (Python's Mersenne Twister) and the exposure of these IDs as filenames in a world-listable `/tmp` directory, potentially leading to OS-level code execution or denial of service by injecting keystrokes or terminating sessions.

Operator session tokens in ForgeKeep's nebula-mesh application are stored in plaintext within the database, allowing an attacker who gains read access to the database to retrieve active session tokens and hijack operator sessions, bypassing further authentication.

A remote attacker can exploit a critical vulnerability, CVE-2026-61500, in Rejetto HFS versions 3.0.0 through 3.2.0 by recovering the session-cookie signing key due to poor randomness, forging an administrator session, and achieving remote code execution.

CVE-2026-38968 affects ntopng versions up to 6.6, enabling session hijacking through predictable session identifiers generated with weak time-seeded pseudo-randomness in `src/HTTPserver.cpp`, allowing attackers to gain unauthorized access to legitimate user sessions.

This rule detects potential session hijacking or token replay in Microsoft Entra ID, identifying cases where a user signs in and subsequently accesses Microsoft Graph from a different IP address using the same session ID, which may indicate a successful OAuth phishing attack, session hijacking, or token replay attack.

ABB B&R Automation Runtime versions before 6.4 are vulnerable to predictable number generation (CVE-2025-3449), reflected XSS (CVE-2025-3448), and CSV injection (CVE-2025-11498), potentially allowing attackers to hijack sessions or execute arbitrary code in a user's browser context.

The Gremlin stealer malware has evolved with advanced obfuscation techniques, crypto clipping, and session hijacking capabilities to steal sensitive information from compromised systems.

Siemens SIPROTEC 5 devices are vulnerable to session hijacking (CVE-2024-54017) due to the use of insufficiently random numbers in session identifier generation, potentially allowing an unauthenticated remote attacker to brute-force a valid session and gain unauthorized read access.

CVE-2026-2347 describes an authorization bypass vulnerability through a user-controlled key in Akilli Commerce Software Technologies Ltd. Co. E-Commerce Website before version 4.5.001, which could lead to session hijacking.

Multiple vulnerabilities in Spring Boot, including CVE-2026-40976, CVE-2026-40973, and CVE-2026-40972, can allow attackers to bypass authorization, hijack sessions, or achieve remote code execution, potentially leading to data breaches and system compromise.

Multiple vulnerabilities in n8n can be exploited by an attacker to execute arbitrary code, bypass security measures, disclose sensitive information, conduct SQL injection attacks, cause denial-of-service, perform cross-site scripting, redirect users, or hijack sessions.

Auth0-PHP SDK versions 8.0.0 to before 8.19.0 encrypt cookies with insufficient entropy, potentially allowing attackers to brute-force the encryption key and forge session cookies.

Unauthenticated attackers can exploit CVE-2026-3055 (out-of-bounds read) to exfiltrate sensitive data from NetScaler ADC and Gateway, while CVE-2026-4368 (race condition) enables user session hijacking, necessitating immediate patching and enhanced monitoring.

An anonymous remote attacker can exploit multiple vulnerabilities in Red Hat JBoss Enterprise Application Platform to cause a denial-of-service condition, manipulate data, and conduct further attacks such as cache poisoning and session hijacking.

An authenticated remote attacker can exploit a vulnerability in Checkmk to bypass security measures, leading to session hijacking.

An anonymous or authenticated remote attacker can exploit multiple vulnerabilities in Citrix Systems NetScaler to disclose information and take over a user session.

A race condition vulnerability in NetScaler ADC and Gateway (CVE-2026-3055 and CVE-2026-4368) could lead to user session mixup, potentially allowing unauthorized access to sensitive information.

PraisonAI Browser Server is vulnerable to unauthenticated WebSocket client hijacking due to exposing the browser bridge on 0.0.0.0 by default and accepting WebSocket clients that omit the Origin header, allowing unauthorized remote use of a connected browser automation session.

OpenMage LTS version 20.16.0 and earlier has a critical vulnerability in the XML-RPC/SOAP API session ID generation, which uses a predictable MD5 hash of time-derived inputs, allowing attackers to brute-force and hijack active API sessions for data exfiltration, order fraud, and supply chain manipulation.

Detection of multiple device token hashes and source IPs for a single Okta session, indicating potential session hijacking and unauthorized access to Okta resources.

Detection of AWS IAM accounts exhibiting concurrent sessions originating from different IP addresses within a short timeframe, potentially indicating session hijacking.
