CVE-2026-18093: IBM App Connect Enterprise Incorrect Authorization Vulnerability

IBM Bob 1.0.4 through 2.0.1 could allow a remote attacker to inject arbitrary code on the system, due to the improper control of user input code.

IBM Langflow OSS 1.0.0 through 1.12.2 An authenticated flow author could write attacker-controlled file content into any directory writable by the service account, bypassing the platform's local file access isolation safeguard. Via a crafted on-disk index, the attacker could also read the contents of arbitrary files accessible to the service process — including configuration files, secrets, or database files stored under the application's data directory.

Hibernate Validator could allow a remote attacker to cause a denial of service due to uncontrolled resource consumption resulting from improper escaping of user-controlled data in Expression Language (EL) expressions.

IBM Security Verify Directory 10.0.0 through 10.0.4 and IBM Verify Directory 11.0.0 is vulnerable to session fixation. An attacker can establish a session and, after the victim authenticates, hijack the authenticated session to gain unauthorized access to the directory management console.

IBM Concert 1.0 through 3.0.1.1 allows an attacker can supply crafted input that is incorporated into an operating system command without adequate validation or sanitization. Successful exploitation allows remote attackers to execute arbitrary commands on the underlying operating system with the privileges of the affected service.

IBM Storage TS4500 Library 1.1.1.6 through 1.12.0.3 could allow a remote authenticated attacker to perform unauthorized account takeover due to improper authorization.
