Exploitation Conditions

Exploitation requires the attacker to already have interactive logon access with low privileges (PR:L) to the infrastructure where Oracle HTTP Server executes - this is a local vector (AV:L), not remotely reachable over the network, which is the primary limiting factor. The vulnerable code is in the mod_http2.so HTTP/2 module, so an OHS deployment with that module loaded (the default) is the affected surface. No user interaction is required (UI:N) and attack complexity is low (AC:L), meaning once local access is obtained exploitation is straightforward. The specific configuration trigger beyond 'OHS 14.1.2.0.0 with mod_http2 present' is not disclosed in Oracle's summary. Defenders should note that anything restricting local logon on the middleware host directly reduces exploitability.

Impact

The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 7.8 High) indicates an attacker must already have local logon access to the OHS host and low privileges, but then needs no user interaction and gains full compromise of the server. This is a meaningful privilege-escalation/takeover risk in shared or multi-tenant hosting contexts, but the local-only vector materially limits blast radius compared with a network-reachable HTTP/2 flaw. There is no CISA KEV listing and no public exploit identified, so this is not confirmed actively exploited; EPSS and SSVC data were not provided in the input and cannot be cited. Overall this is a genuine High-severity issue to patch in the normal Oracle CPU cycle rather than an emergency, since the local-access prerequisite raises the bar for opportunistic attackers. Note the tag 'Information Disclosure' in the intelligence feed is narrower than the vector's C:H/I:H/A:H full-takeover impact - treat the CVSS impact as authoritative and the tag as an incomplete label.

Exploit ScenarioDerived

An attacker who already holds a low-privileged local account on the server hosting Oracle HTTP Server - for example a limited operational or developer login on a shared middleware tier - interacts with the vulnerable mod_http2.so code path to escalate to full control of the OHS instance, gaining read/write over its data and the ability to disrupt service. No user interaction or elevated privileges are needed beyond the initial logon. No public proof-of-concept is available at the time of analysis.

AnalysisAIv1 – Jul 22, 2026

Local privilege-driven takeover in Oracle HTTP Server 14.1.2.0.0 (Oracle Fusion Middleware) lets a low-privileged attacker with logon access to the host running OHS fully compromise the server via the bundled HTTP/2 module (mod_http2.so). With a CVSS 3.1 base score of 7.8 and full confidentiality, integrity, and availability impact, successful exploitation yields complete takeover of the OHS instance. Fixed in Oracle's July 2026 Critical Patch Update; no public exploit identified at time of analysis.

RemediationAI

Apply the fixes in Oracle's July 2026 Critical Patch Update, published at https://www.oracle.com/security-alerts/cpujul2026.html - Patch available per vendor advisory; the input does not include a discrete fixed version string, so validate the exact patch/bundle number for Oracle HTTP Server 14.1.2.0.0 directly in the CPU matrix. As interim compensating controls, tighten OS-level access to the OHS host so that only trusted administrators hold local logon rights (the vulnerability requires PR:L local access), enforce least-privilege on the account running the OHS process, and audit shell/interactive access on middleware tiers; if HTTP/2 is not required for your workloads, consider disabling the mod_http2 module in httpd.conf to remove the vulnerable code path, accepting the trade-off that clients fall back to HTTP/1.1 with reduced multiplexing performance. Because the CVE reference (https://nvd.nist.gov/vuln/detail/CVE-2026-60530) may lag, rely on the Oracle CPU page for authoritative patch identifiers.

Technical ContextAI · show details

The affected component is mod_http2.so, the Apache-derived HTTP/2 protocol module shipped with Oracle HTTP Server, the web-tier component of Oracle Fusion Middleware 14.1.2.0.0. mod_http2 implements the HTTP/2 multiplexed binary framing layer (RFC 7540) on top of Apache httpd, handling stream management, header (HPACK) processing, and flow control - historically a source of memory-safety and resource-handling defects. Oracle publishes CWE as N/A for this entry, so the exact root-cause class is not disclosed; the local attack vector (AV:L) combined with full CIA impact suggests a flaw exploitable by a logged-in user against the OHS process (for example via memory corruption, insecure file/permission handling, or process interaction) rather than a purely remote HTTP/2 parsing bug.

DescriptionCVE.org

Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: mod_http2.so). The supported version that is affected is 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle HTTP Server executes to compromise Oracle HTTP Server. Successful attacks of this vulnerability can result in takeover of Oracle HTTP Server. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

Executive ViewAI

Why It Matters

Oracle HTTP Server 14.1.2.0.0 is vulnerable to local privilege escalation through its HTTP/2 module, enabling users with host access to gain complete control of the web server and all hosted applications. Organizations running this version face risk of data breach, service disruption, and unauthorized system access from internal threat actors or compromised user accounts.
