NULL pointer dereference in NGINX JavaScript (njs) crashes NGINX worker processes when an njs script calls ngx.fetch() against a server that returns a malformed HTTP response and subsequently reads Response.statusText on the result. All versions of F5's NGINX JavaScript module are listed as affected per the wildcard CPE, and the impact is confined entirely to the data plane - worker availability - with no control-plane, confidentiality, or integrity exposure. No public exploit code exists and the CVE is not listed in CISA KEV at time of analysis, but the network-accessible path and zero-privilege requirement make this a credible service-disruption risk for any NGINX deployment using njs-based outbound HTTP fetching.
Heap out-of-bounds write in NGINX JavaScript (njs) xml.exclusiveC14n() allows unauthenticated remote attackers to crash NGINX worker processes or cause unbounded memory growth, with theoretical code execution that has not been demonstrated. The vulnerability is directly reachable in the nginxinc/nginx-saml reference SAML SP implementation, which passes untrusted InclusiveNamespaces/@PrefixList values to xml.exclusiveC14n() before signature verification completes - meaning no valid SAML signature is required to trigger it. Both the njs (default) and QuickJS engines are affected, with differing crash-vs-leak behavior, but both result in denial of service. No public exploit is identified at time of analysis.
Annotation injection in F5 NGINX Ingress Controller allows any authenticated Kubernetes principal with write access to Ingress resources to embed arbitrary NGINX configuration directives through unsanitized annotation fields. The configuration generator passes multiple user-controllable annotation values directly into the generated nginx.conf without sanitization, enabling an attacker to inject directives that create or delete files, disable services, or manipulate NGINX routing behavior. Impact is confined to the Kubernetes control plane; the NGINX data plane itself is not directly reachable through this vulnerability.
Configuration injection in NGINX Gateway Fabric allows authenticated Kubernetes users with CRD or Secret write permissions to embed arbitrary NGINX directives into the generated server configuration. The vulnerability originates in the NGINX configuration generator component, which renders Authentication Filter fields - clientID, cookieName, and clientSecret - directly into configuration templates without sanitization. Successful exploitation is limited to the control plane; no data-plane traffic is directly manipulated, but an attacker can introduce directives that compromise confidentiality and integrity of the NGINX Plus configuration. No public exploit has been identified and the issue is not listed in CISA KEV at time of analysis.
NGINX JavaScript (njs) and QuickJS (qjs) fail open during the js_access phase when an exception is thrown inside an asynchronous request-body processing handler before an explicit access-denial is returned. The flaw (CWE-636, Not Failing Securely) allows unauthenticated remote attackers to bypass js_access controls entirely and reach protected backend resources. No public exploit code or CISA KEV listing has been identified at time of analysis; exploitation is bounded by the requirement for a specific async access-handler pattern.
Privilege escalation in F5 BIG-IP and BIG-IQ allows any authenticated user - regardless of assigned role - to create administrative accounts on the device by sending an undisclosed request to the Traffic Management User Interface (TMUI). The flaw is a control-plane-only issue (no data-plane exposure) but grants a low-privileged attacker full administrative authority over the BIG-IP management plane, including traffic policy, certificate management, and device configuration. No public exploit code and no CISA KEV listing have been identified at time of analysis; however, the low attack complexity and broad affected version scope make this a high-priority patching target for any organization running BIG-IP.
Limited memory disclosure and worker-process restart in NGINX Plus and NGINX Open Source arise when the optional ngx_http_slice_module is compiled in and configured alongside unnamed regex captures, or when a background cache update occurs, letting remote attackers trigger uninitialized memory access (CWE-908) in the data plane. The CVSS:4.0 vector (AV:N/AC:L/PR:N/UI:N) indicates unauthenticated network exploitation with no user interaction, scored 8.8. There is no public exploit identified at time of analysis and no CISA KEV listing; F5 has released a patch and the issue does not affect the control plane.
Heap buffer over-read in the ngx_http_ssi_module of NGINX Open Source and NGINX Plus lets an unauthenticated man-in-the-middle attacker who can control upstream responses corrupt worker-process memory or crash the worker, but only in the non-default configuration combining Server-Side Includes, proxy_pass, and proxy_buffering off. The impact is confined to the data plane with no control-plane exposure, yielding limited memory modification and worker restarts (denial of service) rather than full code execution. No public exploit identified at time of analysis, though a vendor patch is available and the flaw carries a CVSS 4.0 score of 8.3.
Heap buffer overflow in NGINX Plus and NGINX Open Source lets unauthenticated remote attackers crash worker processes (DoS) and, on hosts with ASLR disabled or bypassed, potentially execute arbitrary code by sending crafted HTTP requests. The flaw is a data-plane-only issue triggered when a regex-based map directive references the map's regex capture variables before the map output variable in a string expression, or via a non-cacheable variable under certain conditions. F5 has released a patched version; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in F5 NGINX Ingress Controller allows an authenticated remote attacker holding write access to Ingress or TransportServer resources to crash the control plane by submitting a malformed resource. Because the offending resource persists in the cluster, the controller re-reads it and re-crashes, producing a durable crash loop rather than a one-time outage. There is no public exploit identified at time of analysis, and impact is confined to the control plane with no data plane or confidentiality/integrity exposure.
Configuration injection in F5 NGINX Ingress Controller lets an authenticated Kubernetes user with rights to create or modify Ingress CRDs or annotations smuggle arbitrary NGINX directives into the generated configuration. Because multiple user-controllable fields are written to the config without sanitization, an attacker can inject directives that create or delete files and disable services on the control plane. No public exploit identified at time of analysis; this is a control-plane-only issue with no data plane exposure, but the CVSS 4.0 score of 8.7 (High) reflects strong confidentiality and integrity impact.
Memory-exhaustion denial of service in F5 BIG-IP affects any virtual server configured with an HTTP/2 profile, where a remote unauthenticated attacker sends undisclosed crafted requests that drive Traffic Management Microkernel (TMM) memory consumption upward until TMM restarts. This is a data-plane-only issue with no control-plane exposure, and it also impacts the BIG-IP Next family (Kubernetes, SPK, CNF). No public exploit has been identified at time of analysis, and it is not listed in CISA KEV; the vendor rates it CVSS 4.0 8.7 (High).
Denial-of-service in F5 NGINX Gateway Fabric allows an authenticated Kubernetes user with rights to create or modify GRPCRoute resources to crash the control plane by submitting GRPCRoute objects containing malformed backendRef filters. The flaw, tracked under CWE-129 (Improper Validation of Array Index), carries a CVSS 4.0 score of 7.1 with pure availability impact and no public exploit identified at time of analysis.
Configuration injection in F5 NGINX Gateway Fabric allows an authenticated Kubernetes user with permission to create or modify NginxProxy Custom Resource Definitions to inject arbitrary NGINX directives into generated configuration files via the unsanitized access log format setting. The flaw resides in the control plane configuration generator and affects deployments using NGINX Plus or NGINX Open Source as the data plane. There is no public exploit identified at time of analysis, and CVSS 4.0 rates the impact at 8.6 (High) driven by high confidentiality and integrity loss on the vulnerable system.
Configuration injection in F5 NGINX Gateway Fabric lets an authenticated Kubernetes user who can create or modify NginxProxy or AuthenticationFilter Custom Resources inject arbitrary NGINX directives into generated data-plane configuration. The flaw lives in the control-plane config generator, which renders the serverTokens and extraAuthArgs fields into NGINX templates without escaping, so any tenant holding RBAC rights over these CRDs can rewrite the NGINX Plus config that gets deployed. There is no public exploit identified at time of analysis and EPSS is low (0.36%), but SSVC rates the technical impact as total.
Heap-based buffer overflow in NGINX Plus and NGINX Open Source affects deployments that proxy HTTP/2 or gRPC traffic upstream when ignore_invalid_headers is off and large_client_header_buffers exceeds 2 MB. Remote unauthenticated attackers sending oversized headers can crash the worker process, and where ASLR is disabled or bypassable, achieve arbitrary code execution. No public exploit identified at time of analysis and CISA SSVC marks exploitation as 'none', but technical impact is rated total.
Use-after-free in NGINX Open Source's ngx_http_v3_module allows remote unauthenticated attackers to crash worker processes and potentially execute arbitrary code on hosts where HTTP/3 QUIC is enabled. Exploitation requires a specially crafted HTTP/3 session that reopens a QPACK encoder stream, with code execution contingent on ASLR being disabled or bypassed; no public exploit identified at time of analysis, though SSVC technical impact is rated total.
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.
Heap buffer overflow in NGINX Plus and NGINX Open Source ngx_http_rewrite_module can be triggered by unauthenticated remote attackers sending crafted HTTP requests that target rewrite directives using overlapping PCRE captures (e.g., $1$2 referencing ^/((.*))$) in redirect or arguments contexts. Impact ranges from worker process crash/restart to arbitrary code execution where ASLR is disabled or bypassed; publicly available exploit code exists, though EPSS exploitation probability is low (0.15%, 35th percentile) and the issue is not in CISA KEV.
Heap buffer overflow in F5 NGINX JavaScript (njs) module versions 0.9.4 through 0.9.8 allows unauthenticated remote attackers to crash NGINX worker processes, with potential remote code execution on hosts where ASLR is disabled. Exploitation requires the deployment to use the js_fetch_proxy directive with at least one client-controlled NGINX variable (such as $http_*, $arg_*, or $cookie_*) and a location that invokes ngx.fetch(). No public exploit identified at time of analysis, but a vendor patch is available and the CVSS 4.0 base score of 9.2 reflects the high impact across confidentiality, integrity, and availability.
Memory disclosure and denial-of-service in NGINX's SCGI and uWSGI proxy modules allow attackers with man-in-the-middle position between NGINX and upstream servers to read worker process memory or crash the service. Affects both NGINX Open Source and NGINX Plus when scgi_pass or uwsgi_pass directives are configured. The vulnerability requires network positioning between NGINX and its backend servers (AV:N with AT:P - Present attack complexity), making exploitation dependent on network architecture. No public exploit identified at time of analysis. CVSS 8.3 (High) reflects potential for confidential data exposure but limited by MITM prerequisite.
Heap buffer overflow in NGINX Plus and NGINX Open Source ngx_http_rewrite_module allows remote attackers to crash worker processes and potentially execute code on systems without ASLR. The vulnerability requires specific rewrite directive configurations using PCRE captures with question marks in replacement strings, combined with attacker-crafted HTTP requests and conditions beyond the attacker's control. F5 has released patches addressing this critical flaw. EPSS data unavailable; no KEV listing or public exploit identified at time of analysis, though the specific configuration requirements and dependency on external conditions likely limit widespread exploitation despite the 9.2 CVSS score.
Traffic Management Microkernel (TMM) crash in F5 BIG-IP versions 16.1.0 through 21.0.0.1 allows unauthenticated remote attackers to cause complete service disruption when a SIP profile is configured on a virtual server. The vulnerability requires specific configuration (SIP profile deployment) and enables denial of service through undisclosed malformed SIP traffic. EPSS data not available; no active exploitation confirmed by CISA KEV at time of analysis. Vendor patch available across all affected version branches with specific fix versions identified.

EPSS data not available; no confirmed active exploitation or public POC identified at time of analysis. Vendor patch available per F5 K000160945.
Incorrect permission assignment in BIG-IP and BIG-IQ TMOS Shell (tmsh) network diagnostics commands and iControl REST allows authenticated attackers to view network status of destination systems. Affected versions vary by product line; vendor has released patches. Authentication is required, limiting exposure to users with valid credentials, but the high confidentiality impact (CVSS 6.5) makes this a material information disclosure risk for organizations managing sensitive network infrastructure.
Arbitrary command execution in F5 BIG-IP and BIG-IQ Certificate Manager allows highly privileged attackers with Certificate Manager role to run OS commands by modifying configuration objects. The vulnerability requires network access and high privileges (PR:H) but enables scope change (S:C) with high confidentiality and integrity impact. Vendor-released patch available per F5 Security Advisory K000160971. EPSS data not provided; no confirmed active exploitation (not in CISA KEV) or public exploit code identified at time of analysis.
Configuration manipulation in F5 BIG-IP and BIG-IQ Certificate Manager allows authenticated attackers with high privileges to execute arbitrary commands with scope change. Attackers holding Certificate Manager role credentials can modify configuration objects to run system commands, escalating from administrative interface access to underlying system control.

Error message spoofing in F5 BIG-IP's Configuration utility (TMUI) allows a remote, unauthenticated attacker to reflect fabricated error messages inside an authenticated administrator's browser session by tricking them into clicking a crafted link. The flaw is rooted in CWE-451 (UI Misrepresentation of Critical Information) and is strictly a control-plane issue - the data plane handling live traffic is unaffected. F5 has assigned a CVSS 4.0 score of 2.3, reflecting the combination of high attack complexity, mandatory user interaction, and the narrow integrity-only impact of spoofed UI content.
Heap buffer over-read in NGINX Plus's MQTT filter module (ngx_stream_mqtt_filter_module) allows unauthenticated remote attackers to crash the NGINX worker process, causing a brief, recoverable service disruption. The vulnerability is data-plane only - no control plane exposure exists - and exploitation depends partly on runtime conditions outside the attacker's control, reflected by the CVSS 4.0 AT:P metric. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; F5 has released a patch documented in advisory K000162101.
Path traversal in F5 NGINX Agent via the config_dirs directive enables a remotely authenticated low-privileged attacker to read and write files outside of the directories designated as secure in the agent's configuration. The config_dirs directive can be set directly in the NGINX Agent configuration or through NGINX Instance Manager, expanding the attack surface across both products. No public exploit code or active exploitation has been identified at time of analysis, and a vendor patch is available per F5 advisory K000161971.
Heap buffer over-read in NGINX Plus and NGINX Open Source's ngx_http_charset_module exposes limited worker process memory or triggers a worker restart when remote unauthenticated attackers send crafted requests against a non-default charset conversion configuration. Exploitation requires both a specific dual-directive configuration (source_charset utf-8 alongside a differing charset directive such as koi8-r in the same location block) and content-dependent conditions outside the attacker's direct control, reflected in the CVSS AC:H rating. No public exploit code exists and this CVE does not appear in the CISA KEV catalog; the vendor F5 has published advisory K000161585 with patched version guidance.
NGINX Open Source configured to proxy HTTP/2 traffic with proxy_http_version set to 2 combined with proxy_set_body allows remote unauthenticated attackers to inject frame headers and payload bytes to upstream peers, enabling potential header injection or request manipulation attacks. The vulnerability affects default configurations without requiring authentication or user interaction, with CVSS 5.8 indicating moderate integrity impact across networked systems. No public exploit code or active exploitation has been confirmed at this time.
NGINX Plus and NGINX Open Source configured with the HTTP/3 QUIC module allows unauthenticated remote attackers to spoof source IP addresses, enabling bypass of authorization checks and rate-limiting controls. The vulnerability affects both commercial and open-source variants when QUIC is explicitly enabled, with patches available from F5.
Heap buffer over-read in NGINX's ngx_http_charset_module allows unauthenticated remote attackers to leak sensitive memory or crash worker processes when specific configuration directives (charset, source_charset, charset_map, and proxy_pass with buffering disabled) are combined. The vulnerability requires attacker-controlled conditions that depend on factors outside the attacker's control, limiting exploitability but creating real risk for affected deployments. CVSS 4.8 reflects the conditional nature of exploitation and limited scope of impact (information disclosure or availability).
Heap-use-after-free in NGINX Plus and NGINX Open Source allows unauthenticated remote attackers to trigger memory corruption in the worker process when ssl_verify_client is set to 'on' or 'optional' and ssl_ocsp is configured with a resolver. Exploitation can cause limited information disclosure or worker process restart, with CVSS 4.8 reflecting moderate impact constrained by high attack complexity. No public exploit code or active exploitation has been identified at time of analysis.
Directory traversal vulnerability in F5 BIG-IP iControl REST endpoint when running in Appliance mode allows authenticated administrators to delete arbitrary files, crossing security boundaries. The vulnerability requires high-privilege administrator role access and network connectivity to the iControl REST interface, but no user interaction. Patch availability confirmed from F5; no active exploitation reported.
F5 BIG-IP iControl REST API allows authenticated attackers to enumerate local user account names through undisclosed requests, leading to information disclosure of administrative user identities. The vulnerability requires valid authentication credentials and network access to the iControl REST interface, affecting systems with BIG-IP versions that have not reached End of Technical Support. CVSS 4.3 (low) reflects the requirement for prior authentication and confidentiality-only impact, though the enumeration of administrative accounts could facilitate downstream attacks.
Authenticated high-privilege attackers with Resource Administrator or Administrator roles can download sensitive files from F5 BIG-IP iControl SOAP interface due to improper path validation. The vulnerability requires valid administrative credentials and does not affect versions that have reached End of Technical Support, limiting exposure to actively maintained deployments. No public exploit code or active exploitation has been identified.
NULL pointer dereference in NGINX JavaScript (njs) crashes NGINX worker processes when an njs script calls ngx.fetch() against a server that returns a malformed HTTP response and subsequently reads Response.statusText on the result. All versions of F5's NGINX JavaScript module are listed as affected per the wildcard CPE, and the impact is confined entirely to the data plane - worker availability - with no control-plane, confidentiality, or integrity exposure. No public exploit code exists and the CVE is not listed in CISA KEV at time of analysis, but the network-accessible path and zero-privilege requirement make this a credible service-disruption risk for any NGINX deployment using njs-based outbound HTTP fetching.
Heap out-of-bounds write in NGINX JavaScript (njs) xml.exclusiveC14n() allows unauthenticated remote attackers to crash NGINX worker processes or cause unbounded memory growth, with theoretical code execution that has not been demonstrated. The vulnerability is directly reachable in the nginxinc/nginx-saml reference SAML SP implementation, which passes untrusted InclusiveNamespaces/@PrefixList values to xml.exclusiveC14n() before signature verification completes - meaning no valid SAML signature is required to trigger it. Both the njs (default) and QuickJS engines are affected, with differing crash-vs-leak behavior, but both result in denial of service. No public exploit is identified at time of analysis.
Annotation injection in F5 NGINX Ingress Controller allows any authenticated Kubernetes principal with write access to Ingress resources to embed arbitrary NGINX configuration directives through unsanitized annotation fields. The configuration generator passes multiple user-controllable annotation values directly into the generated nginx.conf without sanitization, enabling an attacker to inject directives that create or delete files, disable services, or manipulate NGINX routing behavior. Impact is confined to the Kubernetes control plane; the NGINX data plane itself is not directly reachable through this vulnerability.
Configuration injection in NGINX Gateway Fabric allows authenticated Kubernetes users with CRD or Secret write permissions to embed arbitrary NGINX directives into the generated server configuration. The vulnerability originates in the NGINX configuration generator component, which renders Authentication Filter fields - clientID, cookieName, and clientSecret - directly into configuration templates without sanitization. Successful exploitation is limited to the control plane; no data-plane traffic is directly manipulated, but an attacker can introduce directives that compromise confidentiality and integrity of the NGINX Plus configuration. No public exploit has been identified and the issue is not listed in CISA KEV at time of analysis.
NGINX JavaScript (njs) and QuickJS (qjs) fail open during the js_access phase when an exception is thrown inside an asynchronous request-body processing handler before an explicit access-denial is returned. The flaw (CWE-636, Not Failing Securely) allows unauthenticated remote attackers to bypass js_access controls entirely and reach protected backend resources. No public exploit code or CISA KEV listing has been identified at time of analysis; exploitation is bounded by the requirement for a specific async access-handler pattern.
Privilege escalation in F5 BIG-IP and BIG-IQ allows any authenticated user - regardless of assigned role - to create administrative accounts on the device by sending an undisclosed request to the Traffic Management User Interface (TMUI). The flaw is a control-plane-only issue (no data-plane exposure) but grants a low-privileged attacker full administrative authority over the BIG-IP management plane, including traffic policy, certificate management, and device configuration. No public exploit code and no CISA KEV listing have been identified at time of analysis; however, the low attack complexity and broad affected version scope make this a high-priority patching target for any organization running BIG-IP.
Limited memory disclosure and worker-process restart in NGINX Plus and NGINX Open Source arise when the optional ngx_http_slice_module is compiled in and configured alongside unnamed regex captures, or when a background cache update occurs, letting remote attackers trigger uninitialized memory access (CWE-908) in the data plane. The CVSS:4.0 vector (AV:N/AC:L/PR:N/UI:N) indicates unauthenticated network exploitation with no user interaction, scored 8.8. There is no public exploit identified at time of analysis and no CISA KEV listing; F5 has released a patch and the issue does not affect the control plane.
Heap buffer over-read in the ngx_http_ssi_module of NGINX Open Source and NGINX Plus lets an unauthenticated man-in-the-middle attacker who can control upstream responses corrupt worker-process memory or crash the worker, but only in the non-default configuration combining Server-Side Includes, proxy_pass, and proxy_buffering off. The impact is confined to the data plane with no control-plane exposure, yielding limited memory modification and worker restarts (denial of service) rather than full code execution. No public exploit identified at time of analysis, though a vendor patch is available and the flaw carries a CVSS 4.0 score of 8.3.
Heap buffer overflow in NGINX Plus and NGINX Open Source lets unauthenticated remote attackers crash worker processes (DoS) and, on hosts with ASLR disabled or bypassed, potentially execute arbitrary code by sending crafted HTTP requests. The flaw is a data-plane-only issue triggered when a regex-based map directive references the map's regex capture variables before the map output variable in a string expression, or via a non-cacheable variable under certain conditions. F5 has released a patched version; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in F5 NGINX Ingress Controller allows an authenticated remote attacker holding write access to Ingress or TransportServer resources to crash the control plane by submitting a malformed resource. Because the offending resource persists in the cluster, the controller re-reads it and re-crashes, producing a durable crash loop rather than a one-time outage. There is no public exploit identified at time of analysis, and impact is confined to the control plane with no data plane or confidentiality/integrity exposure.
Configuration injection in F5 NGINX Ingress Controller lets an authenticated Kubernetes user with rights to create or modify Ingress CRDs or annotations smuggle arbitrary NGINX directives into the generated configuration. Because multiple user-controllable fields are written to the config without sanitization, an attacker can inject directives that create or delete files and disable services on the control plane. No public exploit identified at time of analysis; this is a control-plane-only issue with no data plane exposure, but the CVSS 4.0 score of 8.7 (High) reflects strong confidentiality and integrity impact.
Memory-exhaustion denial of service in F5 BIG-IP affects any virtual server configured with an HTTP/2 profile, where a remote unauthenticated attacker sends undisclosed crafted requests that drive Traffic Management Microkernel (TMM) memory consumption upward until TMM restarts. This is a data-plane-only issue with no control-plane exposure, and it also impacts the BIG-IP Next family (Kubernetes, SPK, CNF). No public exploit has been identified at time of analysis, and it is not listed in CISA KEV; the vendor rates it CVSS 4.0 8.7 (High).
Denial-of-service in F5 NGINX Gateway Fabric allows an authenticated Kubernetes user with rights to create or modify GRPCRoute resources to crash the control plane by submitting GRPCRoute objects containing malformed backendRef filters. The flaw, tracked under CWE-129 (Improper Validation of Array Index), carries a CVSS 4.0 score of 7.1 with pure availability impact and no public exploit identified at time of analysis.
Configuration injection in F5 NGINX Gateway Fabric allows an authenticated Kubernetes user with permission to create or modify NginxProxy Custom Resource Definitions to inject arbitrary NGINX directives into generated configuration files via the unsanitized access log format setting. The flaw resides in the control plane configuration generator and affects deployments using NGINX Plus or NGINX Open Source as the data plane. There is no public exploit identified at time of analysis, and CVSS 4.0 rates the impact at 8.6 (High) driven by high confidentiality and integrity loss on the vulnerable system.
Configuration injection in F5 NGINX Gateway Fabric lets an authenticated Kubernetes user who can create or modify NginxProxy or AuthenticationFilter Custom Resources inject arbitrary NGINX directives into generated data-plane configuration. The flaw lives in the control-plane config generator, which renders the serverTokens and extraAuthArgs fields into NGINX templates without escaping, so any tenant holding RBAC rights over these CRDs can rewrite the NGINX Plus config that gets deployed. There is no public exploit identified at time of analysis and EPSS is low (0.36%), but SSVC rates the technical impact as total.
Heap-based buffer overflow in NGINX Plus and NGINX Open Source affects deployments that proxy HTTP/2 or gRPC traffic upstream when ignore_invalid_headers is off and large_client_header_buffers exceeds 2 MB. Remote unauthenticated attackers sending oversized headers can crash the worker process, and where ASLR is disabled or bypassable, achieve arbitrary code execution. No public exploit identified at time of analysis and CISA SSVC marks exploitation as 'none', but technical impact is rated total.
Use-after-free in NGINX Open Source's ngx_http_v3_module allows remote unauthenticated attackers to crash worker processes and potentially execute arbitrary code on hosts where HTTP/3 QUIC is enabled. Exploitation requires a specially crafted HTTP/3 session that reopens a QPACK encoder stream, with code execution contingent on ASLR being disabled or bypassed; no public exploit identified at time of analysis, though SSVC technical impact is rated total.
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.
Heap buffer overflow in NGINX Plus and NGINX Open Source ngx_http_rewrite_module can be triggered by unauthenticated remote attackers sending crafted HTTP requests that target rewrite directives using overlapping PCRE captures (e.g., $1$2 referencing ^/((.*))$) in redirect or arguments contexts. Impact ranges from worker process crash/restart to arbitrary code execution where ASLR is disabled or bypassed; publicly available exploit code exists, though EPSS exploitation probability is low (0.15%, 35th percentile) and the issue is not in CISA KEV.
Heap buffer overflow in F5 NGINX JavaScript (njs) module versions 0.9.4 through 0.9.8 allows unauthenticated remote attackers to crash NGINX worker processes, with potential remote code execution on hosts where ASLR is disabled. Exploitation requires the deployment to use the js_fetch_proxy directive with at least one client-controlled NGINX variable (such as $http_*, $arg_*, or $cookie_*) and a location that invokes ngx.fetch(). No public exploit identified at time of analysis, but a vendor patch is available and the CVSS 4.0 base score of 9.2 reflects the high impact across confidentiality, integrity, and availability.
Memory disclosure and denial-of-service in NGINX's SCGI and uWSGI proxy modules allow attackers with man-in-the-middle position between NGINX and upstream servers to read worker process memory or crash the service. Affects both NGINX Open Source and NGINX Plus when scgi_pass or uwsgi_pass directives are configured. The vulnerability requires network positioning between NGINX and its backend servers (AV:N with AT:P - Present attack complexity), making exploitation dependent on network architecture. No public exploit identified at time of analysis. CVSS 8.3 (High) reflects potential for confidential data exposure but limited by MITM prerequisite.
Heap buffer overflow in NGINX Plus and NGINX Open Source ngx_http_rewrite_module allows remote attackers to crash worker processes and potentially execute code on systems without ASLR. The vulnerability requires specific rewrite directive configurations using PCRE captures with question marks in replacement strings, combined with attacker-crafted HTTP requests and conditions beyond the attacker's control. F5 has released patches addressing this critical flaw. EPSS data unavailable; no KEV listing or public exploit identified at time of analysis, though the specific configuration requirements and dependency on external conditions likely limit widespread exploitation despite the 9.2 CVSS score.

Buffer overflow in NGINX's DAV module allows remote attackers to crash worker processes or manipulate file names outside the document root when MOVE/COPY methods are combined with prefix location and alias directives. The vulnerability affects NGINX Open Source and NGINX Plus installations using vulnerable configurations, though the low-privilege worker process context limits the scope of file manipulation. No patch is currently available for this high-severity issue.
NGINX Open Source and NGINX Plus contain a buffer over-read or over-write vulnerability in the ngx_http_mp4_module that can lead to NGINX worker process termination or potentially remote code execution. An attacker with local access and the ability to supply a specially crafted MP4 file for processing can exploit this flaw when the mp4 directive is enabled in the configuration. The vulnerability has a CVSS score of 7.8 with high impact on confidentiality, integrity, and availability, though exploitation requires local access (AV:L) and low-level privileges (PR:L).
Integer overflow in NGINX 32-bit builds with the ngx_http_mp4_module allows local attackers to corrupt or overwrite worker process memory via specially crafted MP4 files, leading to denial of service.

Error message spoofing in F5 BIG-IP's Configuration utility (TMUI) allows a remote, unauthenticated attacker to reflect fabricated error messages inside an authenticated administrator's browser session by tricking them into clicking a crafted link. The flaw is rooted in CWE-451 (UI Misrepresentation of Critical Information) and is strictly a control-plane issue - the data plane handling live traffic is unaffected. F5 has assigned a CVSS 4.0 score of 2.3, reflecting the combination of high attack complexity, mandatory user interaction, and the narrow integrity-only impact of spoofed UI content.
Heap buffer over-read in NGINX Plus's MQTT filter module (ngx_stream_mqtt_filter_module) allows unauthenticated remote attackers to crash the NGINX worker process, causing a brief, recoverable service disruption. The vulnerability is data-plane only - no control plane exposure exists - and exploitation depends partly on runtime conditions outside the attacker's control, reflected by the CVSS 4.0 AT:P metric. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; F5 has released a patch documented in advisory K000162101.
Path traversal in F5 NGINX Agent via the config_dirs directive enables a remotely authenticated low-privileged attacker to read and write files outside of the directories designated as secure in the agent's configuration. The config_dirs directive can be set directly in the NGINX Agent configuration or through NGINX Instance Manager, expanding the attack surface across both products. No public exploit code or active exploitation has been identified at time of analysis, and a vendor patch is available per F5 advisory K000161971.
Heap buffer over-read in NGINX Plus and NGINX Open Source's ngx_http_charset_module exposes limited worker process memory or triggers a worker restart when remote unauthenticated attackers send crafted requests against a non-default charset conversion configuration. Exploitation requires both a specific dual-directive configuration (source_charset utf-8 alongside a differing charset directive such as koi8-r in the same location block) and content-dependent conditions outside the attacker's direct control, reflected in the CVSS AC:H rating. No public exploit code exists and this CVE does not appear in the CISA KEV catalog; the vendor F5 has published advisory K000161585 with patched version guidance.
