IBM disclosed two vulnerabilities in traditional **IBM WebSphere Application Server** affecting versions **9.0** and **8.5**, led by **CVE-2026-14512**, a **pre-authentication unsafe deserialization** flaw rated **CVSS 9.8**. The issue could allow a remote attacker to **bypass authentication** or achieve **arbitrary code execution** without user interaction, creating a high-risk path to full compromise of exposed WebSphere environments. IBM also identified **CVE-2026-14528**, a **CVSS 7.4** flaw that could expose sensitive information through insertion into log files. The company directed customers to apply the interim fix for **APAR PH72166** or upgrade to **Fix Pack 9.0.5.29+** for WebSphere 9.0 and **Fix Pack 8.5.5.31+** for WebSphere 8.5, and said **no workarounds or mitigations are available**.

IBM disclosed a critical `CVE-2026-8633` vulnerability in WebSphere Application Server and WebSphere Liberty deployments that use the optional **Web Server Plug-ins** component, warning that unauthenticated attackers can send specially crafted HTTP requests to execute arbitrary commands on the host. The flaw, classified as improper control of code generation (`CWE-94`) and rated `CVSS 9.8`, affects WebSphere Application Server traditional and Liberty versions `8.5` and `9.0`, with successful exploitation potentially leading to full system compromise. IBM also patched `CVE-2026-8620`, an HTTP request smuggling issue that could let attackers bypass security controls and manipulate backend communications in affected environments. The company said both issues are addressed through **APAR `PH71342`** and related fix packs, and advised administrators to apply the fixes, validate updates in non-production environments, monitor HTTP traffic, restrict exposure of plug-in endpoints, use WAF protections, and perform threat hunting for signs of exploitation.
