CVE-2026-60530 Jul 21, 22:17 HIGH This Week

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.

Local privilege-based takeover of Oracle HTTP Server (12.2.1.4.0 and 14.1.2.0.0) allows a low-privileged attacker with a logon session on the host to fully compromise the web server, yielding high confidentiality, integrity, and availability impact. Disclosed in Oracle's July 2026 Critical Patch Update, the flaw carries a CVSS 3.1 base score of 7.8 with a local attack vector (AV:L). There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but complete server takeover makes it a meaningful lateral-movement and privilege-consolidation target once a foothold exists.

Unauthenticated compromise of Oracle HTTP Server 12.2.1.4.0 and 14.1.2.0.0 (a Fusion Middleware component) is possible over the network via HTTP against the mod_ssl module, letting a remote attacker read, create, delete or modify all server-accessible data. Rated CVSS 3.1 9.1 with high confidentiality and integrity impact but no availability impact, and tagged as an authentication bypass. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the trivial exploitability (AV:N/AC:L/PR:N/UI:N) makes it a high-priority patch.

Unauthorized data disclosure in Oracle HTTP Server 12.2.1.4.0 and 14.1.2.0.0 (Oracle Fusion Middleware, mod_proxy component) lets an unauthenticated remote attacker over HTTP read critical data and, because of a scope change, reach data belonging to other back-end products the proxy fronts. The confidentiality-only impact combined with S:C strongly indicates a proxy-side request-forwarding/SSRF-class weakness that exposes internal resources rather than a code-execution flaw.

Unauthenticated remote compromise of the Oracle WebLogic Server Proxy Plug-in (version 15.1.1.0.0), a module that fronts WebLogic behind third-party web servers such as Apache HTTP Server and Oracle HTTP Server, allowing a network attacker to read and modify critical data with no credentials or user interaction. Oracle rates this a maximum CVSS 3.1 10.0 because the flaw crosses a trust boundary (scope change), meaning exploitation of the plug-in significantly impacts additional connected products. Vendor tagging identifies it as an authentication bypass; there is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the trivial exploitability warrants urgent patching.

Denial of service against HTTP/2 server implementations allows remote unauthenticated attackers to exhaust server resources by rapidly opening and immediately canceling (RST_STREAM) large numbers of streams over a single connection, a technique dubbed the 'Rapid Reset' attack. The flaw is confirmed actively exploited (CISA KEV) following large-scale weaponization observed August through October 2023, with publicly available exploit code and an EPSS score of 94.45% placing it in the 100th percentile for likelihood of exploitation. Virtually every major HTTP/2 stack - including nghttp2, Netty, Envoy, and Eclipse Jetty - is affected.

Reflected XSS in AdonisJS HTTP Server (versions 8.0.0-next.0 through 8.2.0 and 9.0.0 through 9.0.2) enables remote unauthenticated attackers to execute arbitrary JavaScript in a victim's browser by crafting a malicious 404 URL containing an embedded HTML payload. The framework's default exception handler interpolates the unescaped request path directly into the HTML error response when debug mode is disabled and no custom error handler is configured. No public exploit has been identified at time of analysis, but the fix commit includes a working proof-of-concept test demonstrating a cookie-exfiltration attack using `fetch('/dashboard',{credentials:'include'})`, confirming practical exploitability.
