IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to obtain sensitive information due to an out-of-bounds read.CVE-2026-16861ibmiEPSS score0.49%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to an out-of-bounds read.CVE-2026-16722ibmiEPSS score0.50%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain unauthorized privileges due to improper privilege management.CVE-2026-16868ibmiEPSS score0.52%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to the use of uninitialized memory during ASN.1 length processing.CVE-2026-16967ibmiEPSS score0.35%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to gain unauthorized access to system objects due to a time-of-check to time-of-use (TOCTOU) race condition involving symbolic links.CVE-2026-16904ibmiEPSS score0.52%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary commands due to improper privilege management during monitor owner reassignment.CVE-2026-16961ibmiEPSS score0.45%
IBM i 7.6, 7.5, and 7.4 s vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, which could allow the attacker to view, add, modify, or delete information in the back-end database.CVE-2026-16674ibmiEPSS score0.75%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary code due to an untrusted search path.CVE-2026-16975ibmiEPSS score0.75%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary code due to a heap-based buffer overflow.CVE-2026-16694ibmiEPSS score0.23%
IBM i 7.6, 7.5, 7.4, and 7.3 is vulnerable to stored cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.CVE-2026-16987ibmiEPSS score0.15%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local attacker to gain elevated privileges due to improper validation of the LANG environment variable.CVE-2026-16863ibmiEPSS score0.47%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information due to an out-of-bounds read.CVE-2026-16859ibmiEPSS score0.40%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to obtain sensitive information due to an out-of-bounds read.CVE-2026-2311ibmiEPSS score0.20%
IBM i 7.6, 7.5, 7.4, 7.3, and 7.2 s vulnerable to privilege escalation caused by an invalid IBM i Web Administration GUI authorization check. A malicious actor could cause user-controlled code to run with administrator privilege.CVE-2026-84414ibmiEPSS score0.09%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to change the ownership of arbitrary files due to improper validation of an attacker-controlled file path.CVE-2026-1376ibmiEPSS score0.53%
IBM i 7.6 could allow a remote attacker to cause a denial of service using failed authentication connections due to improper allocation of resources.CVE-2026-19086ibmiEPSS score0.12%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a denial of service as a result of a buffer overflow in a PASE process. An authenticated attacker could leverage this to terminate their own process.CVE-2026-19280ibmiEPSS score0.12%
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a denial of service as a result of a buffer overflow in a PASE process. An authenticated attacker could leverage this to terminate their own process.CVE-2026-9072ibmi+1EPSS score0.72%
IBM WebSphere Application Server and IBM WebSphere Application Server Liberty - when using Intelligent Management with the WebSphere WebServer Plug-in component - are vulnerable to remote code execution and denial of service. This vulnerability can be exploited when an attacker impersonates backend servers and sends crafted responses to the plug-in.
