Http Server

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.

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. Addressed in the Oracle Critical Patch Update of July 2026; no public exploit identified at time of analysis and it is not listed in CISA KEV.

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.

Unauthorized data modification in Oracle WebLogic Server Proxy Plug-in (the proxy module for third-party web servers such as Apache/Oracle HTTP Server) lets a remote, unauthenticated attacker tamper with critical data over HTTP. Oracle's authoritative scoring rates this CVSS 3.1 7.5 with integrity-only impact (I:H, C:N, A:N), disclosed in the July 2026 Critical Patch Update and tagged as an authentication-bypass class issue. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV.

Full compromise of Oracle HTTP Server (Oracle Fusion Middleware) is possible via the bundled Apache Plugin (mod_wl/proxy) component in supported versions 12.2.1.4.0 and 14.1.2.0.0, allowing a network-based unauthenticated attacker to take over the server over HTTP. Rated CVSS 3.1 9.8 with high confidentiality, integrity, and availability impact, this is one of the highest-severity issues in Oracle's July 2026 Critical Patch Update. No public exploit identified at time of analysis, but the low-complexity, no-privilege, no-interaction profile makes it a top-priority patch.

Denial of service in Apache HTTP Server 2.4.17 through 2.4.67 (via the bundled mod_http2 module) allows remote unauthenticated attackers to exhaust server memory by sending crafted HTTP/2 requests whose cookie headers are not correctly counted against LimitRequestFields. Publicly available exploit code exists and a third-party write-up describes a 'hidden HTTP/2 bomb,' but EPSS exploitation probability is currently very low (0.02%, 5th percentile) and the CVE is not on the CISA KEV list.

Invalid pointer dereference in IBM HTTP Server 8.5 and 9.0 allows an authenticated privileged user on the Administration Server to expose sensitive information or trigger a denial-of-service condition. The flaw requires adjacent network access and existing low-level privileges, and no public exploit identified at time of analysis. EPSS exploitation probability is negligible (0.01%) and CISA SSVC indicates no observed exploitation.

Heap-based buffer overflow in IBM HTTP Server 8.5 and 9.0 allows an attacker already authenticated to the Administration Server to execute arbitrary code or crash the service. The flaw requires adjacent network access and existing low-level privileges, and no public exploit identified at time of analysis despite the high CVSS 8.0 rating. EPSS probability is negligible (0.01%) and SSVC marks exploitation as 'none,' indicating the issue is currently a patch-and-move-on item rather than an emergency.

Remote code execution and denial of service affect IBM HTTP Server 8.5 and 9.0 when deployed with TLS mutual (client certificate) authentication enabled. The flaw is a code injection weakness (CWE-94) that a network-based attacker can leverage to fully compromise confidentiality, integrity, and availability. No public exploit has been identified at time of analysis, and the EPSS probability is low (0.24%, 47th percentile), indicating no observed weaponization yet despite the maximal 9.8 CVSS.

Denial of service in IBM HTTP Server 8.5 and 9.0 allows remote unauthenticated attackers to crash or degrade the service when the optional mod_mem_cache module is loaded. The flaw carries a CVSS 7.5 (availability-only impact) and has no public exploit identified at time of analysis, though the SSVC framework rates exploitation as automatable. EPSS probability is very low (0.01%, 3rd percentile), suggesting limited near-term exploitation interest.

Denial of service in IBM HTTP Server 8.5 and 9.0 lets an actor with write access to portions of the server configuration render the web server unavailable (CWE-400 resource exhaustion). IBM has released a fix and there is no public exploit identified at time of analysis; EPSS is negligible at 0.03% and CISA SSVC rates exploitation as 'none', indicating a low-urgency, precondition-heavy issue despite the 9.1 base score.

Denial of service in IBM HTTP Server 8.5 and 9.0 allows remote attackers to crash the server by triggering a reachable assertion in the optional mod_fastcgi module. The flaw affects availability only (no data exposure or code execution) and, per the CVSS PR:N vector, requires no authentication, but exploitation depends on the non-default mod_fastcgi module being enabled. There is no public exploit identified at time of analysis, EPSS is very low (0.03%, 9th percentile), and it is not listed in CISA KEV.

Denial of service in IBM HTTP Server 8.5 and 9.0 allows remote unauthenticated attackers to crash the web server when the optional mod_ibm_upload module is loaded, triggering a null pointer dereference (CWE-476). No public exploit identified at time of analysis, and EPSS exploitation probability is very low at 0.02% (4th percentile), though SSVC flags the issue as automatable with partial technical impact. Affected deployments include HTTP Server 8.5 up to Interim Fix 002 and HTTP Server 9.0, with a vendor patch available via IBM support note 7274065.

Oracle HTTP Server and WebLogic Server Proxy Plug-in have a CVSS 10.0 access control vulnerability allowing unauthenticated network attackers to fully compromise the middleware layer.
