Certificate chain validation bypass in wolfSSL's OpenSSL compatibility layer allows authenticated network attackers to forge arbitrary certificates. Attackers possessing any legitimate leaf certificate from a trusted CA can craft fraudulent certificates for any subject name with arbitrary keys, bypassing signature verification when an untrusted CA:FALSE intermediate is inserted. Affects nginx and haproxy integrations using wolfSSL's OpenSSL compatibility API; native wolfSSL TLS handshake (ProcessPeerCerts) not vulnerable. No public exploit identified at time of analysis.

DNS rebinding in Model Context Protocol (MCP) Java SDK before v1.0.0 enables remote attackers to invoke arbitrary tool calls on local or network-private MCP servers via a victim's browser. The SDK failed to validate Origin headers per MCP specification requirements, violating mandatory server-side protections against cross-origin attacks. Exploitation requires social engineering (victim visits malicious site), but grants full tool invocation privileges as if the attacker were a locally authorized AI agent. Patch available in v1.0.0. No public exploit identified at time of analysis, but attack technique is well-understood (DNS rebinding). EPSS data not available; authentication requirements not confirmed from available data.

Authentication bypass in OneUptime notification API endpoints allows unauthenticated remote attackers to manipulate Twilio account resources via missing authorization middleware. Affects all versions prior to 10.0.42. Attackers can purchase phone numbers on victim Twilio accounts and delete configured alerting numbers by exploiting unprotected /notification/ endpoints, using leaked projectId values from public Status Page APIs. No public exploit identified at time of analysis, though attack complexity is rated high (CVSS AC:H) and proof-of-concept details are available in the GitHub security advisory.

Rack::Sendfile in versions prior to 2.2.23, 3.1.21, and 3.2.6 allows remote attackers to inject regex metacharacters into X-Accel-Mapping request headers, enabling unescaped interpolation that manipulates the X-Accel-Redirect response header and causes nginx to serve unintended files from internal locations. No public exploit code or active exploitation has been confirmed; patch versions are available from the vendor.

Stored cross-site scripting (XSS) in phpMyFAQ 4.2.0-alpha allows unauthenticated attackers to inject malicious JavaScript via RFC 5321-compliant quoted email addresses in guest FAQ submissions. The injected payload is stored without sanitization and rendered using Twig's |raw filter in the admin FAQ editor, executing in administrator browsers and enabling session hijacking, admin account takeover, and arbitrary site manipulation. A publicly available proof-of-concept demonstrates successful JavaScript execution when administrators review pending FAQs.

Remote unauthenticated nginx service takeover in nginx-ui's MCP integration allows network attackers to create, modify, or delete nginx configuration files and trigger automatic reloads without authentication. The /mcp_message endpoint lacks authentication middleware while exposing the same MCP tool handlers as the protected /mcp endpoint, and the IP whitelist defaults to empty (allow-all). Attackers can inject malicious server blocks to intercept credentials, exfiltrate backend topology, or crash nginx with invalid configs. CVSS 9.8 (Critical) with network attack vector, no authentication required, and high impact across confidentiality, integrity, and availability. No public exploit identified at time of analysis, though detailed proof-of-concept HTTP request provided in advisory.

Insecure Direct Object Reference (IDOR) in nginx-ui up to v2.3.3 allows authenticated low-privilege users to access, modify, and delete any resource across all user accounts, including plaintext DNS provider API tokens (Cloudflare, AWS Route53, Alibaba Cloud) and ACME private keys. The application's base Model struct lacks user_id fields, and all resource endpoints query by ID without ownership verification. CVSS 8.8 reflects scope change to external services—stolen Cloudflare tokens enable DNS hijacking and fraudulent certificate issuance. No public exploit identified at time of analysis, but trivial to execute via standard HTTP requests. Vendor-released patch: v2.3.4.

Authenticated denial of service in nginx-ui 2.3.3 and earlier allows any user with settings access to submit a negative integer for the logrotate.interval parameter, triggering an infinite loop in the backend that exhausts CPU resources and renders the web interface unresponsive. Vendor-released patch available in v2.3.4. No public exploit code identified beyond proof-of-concept documentation; not confirmed as actively exploited.

Race condition in nginx-ui web interface allows remote authenticated attackers to corrupt the primary configuration file (app.ini) through concurrent API requests, resulting in persistent denial of service and potential remote code execution. The vulnerability affects nginx-ui versions prior to 2.3.4 deployed in production environments including Docker containers. Concurrent POST requests to /api/settings trigger unsynchronized file writes that interleave at the OS level, corrupting configuration sections and creating cross-contamination between INI fields. In non-deterministic scenarios, user-controlled input can overwrite shell command fields (ReloadCmd, RestartCmd), enabling arbitrary command execution during nginx reload operations. Public exploit code demonstrates the attack path using standard HTTP testing tools. No CISA KEV listing or EPSS data available at time of analysis, but proof-of-concept with detailed reproduction steps exists in the GitHub security advisory.

Authenticated users in nginx-ui v2.3.3 and earlier can delete the entire `/etc/nginx` configuration directory via path traversal using double-encoded sequences (..%252F), causing immediate Nginx service failure and denial of service. The vulnerability exploits improper URL canonicalization combined with unsafe recursive deletion logic that resolves malicious paths to the base configuration directory instead of rejecting them.

Remote authenticated attackers can achieve arbitrary command execution on nginx-ui v2.3.3 servers by manipulating encrypted backup archives during restoration. The vulnerability stems from a circular trust model where backup integrity metadata is encrypted using the same AES key provided to clients, allowing attackers to decrypt backups, inject malicious configuration (including command execution directives), recompute valid hashes, and re-encrypt the archive. The restore process accepts tampered backups despite hash verification warnings. Publicly available exploit code exists with detailed proof-of-concept demonstrating configuration injection leading to arbitrary command execution. Vendor-released patch available in nginx-ui v2.3.4. This represents a regression from GHSA-g9w5-qffc-6762, which addressed backup access control but not the underlying cryptographic design flaw.

Fleet server memory exhaustion via unbounded request bodies allows unauthenticated denial-of-service against multiple HTTP endpoints. The vulnerability affects Fleet v4 (github.com/fleetdm/fleet/v4) and was responsibly disclosed by @fuzzztf. Attackers can exhaust available memory and force server restarts by sending oversized or repeated HTTP requests to unauthenticated endpoints lacking size limits. No public exploit identified at time of analysis, though the attack mechanism is straightforward given the CWE-770 resource allocation vulnerability class.

The yansongda/pay PHP library contains an authentication bypass vulnerability that allows attackers to forge WeChat Pay payment notifications by including a 'Host: localhost' header in HTTP requests. The verify_wechat_sign() function unconditionally skips RSA signature verification when it detects localhost as the hostname, enabling attackers to send fake payment success callbacks that applications may process as legitimate transactions. A proof-of-concept exploit exists demonstrating the attack, though the vendor notes most production environments with properly configured reverse proxies, WAFs, or CDNs will reject forged Host headers, significantly reducing real-world exploitability.

NGINX worker process crashes via null pointer dereference in the mail authentication module when CRAM-MD5 or APOP authentication is configured with retry-enabled backend servers. This denial of service vulnerability affects NGINX Plus and NGINX Open Source with no patch currently available, allowing unauthenticated remote attackers to terminate worker processes and degrade service availability.

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 Plus and NGINX Open Source contain an authentication bypass vulnerability in the ngx_stream_ssl_module where revoked certificates are incorrectly accepted during TLS handshakes despite OCSP checking. When ssl_verify_client and ssl_ocsp are both enabled, the module fails to properly enforce certificate revocation status, allowing clients with revoked certificates to establish connections. This affects both commercial NGINX Plus and open-source NGINX deployments with a CVSS score of 5.4 (Medium), representing a localized confidentiality and integrity impact requiring authenticated attackers.

NGINX Plus and NGINX Open Source contain an improper handling vulnerability in the ngx_mail_smtp_module that allows DNS response injection through malformed CRLF sequences. An attacker controlling a DNS server can inject arbitrary headers into SMTP upstream requests, potentially manipulating mail routing and message content. With a CVSS score of 3.7 and low attack complexity, this represents an integrity issue rather than a critical exploitability threat, though it requires network-level DNS control.

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. The vulnerability requires the mp4 directive to be enabled in the configuration and an attacker's ability to trigger MP4 file processing. No patch is currently available for affected deployments.

An unauthenticated server-side request forgery (SSRF) vulnerability exists in AVideo's Live plugin test.php endpoint that allows remote attackers to force the server to send HTTP requests to arbitrary URLs. The vulnerability affects AVideo installations with the Live plugin enabled and can be exploited to probe internal network services, access cloud metadata endpoints, and retrieve content from internal HTTP resources. A proof-of-concept has been published demonstrating localhost service enumeration, and the vulnerability requires no authentication or user interaction to exploit.

Ory Oathkeeper, an identity and access proxy, contains an authorization bypass vulnerability via HTTP path traversal that allows attackers to access protected resources without authentication. The vulnerability affects Ory Oathkeeper installations where the software uses un-normalized paths for rule matching, enabling requests like '/public/../admin/secrets' to bypass authentication requirements. With a CVSS score of 10.0 (Critical) and network-based exploitation requiring no privileges or user interaction, this represents a severe authentication bypass, though no current EPSS score or KEV listing indicates limited evidence of active exploitation at this time.

MinIO AIStor's Security Token Service (STS) AssumeRoleWithLDAPIdentity endpoint contains two combined vulnerabilities that enable LDAP credential brute-forcing: distinguishable error messages allowing username enumeration (CWE-204) and missing rate limiting (CWE-307). All MinIO deployments through the final open-source release with LDAP authentication enabled are affected. Unauthenticated network attackers can enumerate valid LDAP usernames, perform unlimited password guessing attacks, and obtain temporary AWS-style STS credentials granting full access to victim users' S3 buckets and objects.

A configuration injection vulnerability in Kubernetes ingress-nginx controller allows authenticated attackers to inject arbitrary nginx configuration through specially crafted Ingress annotations, leading to remote code execution with controller privileges and exposure of all cluster Secrets. The vulnerability has a high CVSS score of 8.8 and affects the ingress-nginx controller's annotation parsing mechanism. No active exploitation (not in KEV) or public POC has been reported, though the attack requires only low privileges and network access.

Denial of service in Nginx via out-of-bounds read during ALPN protocol parsing when ALPN support is enabled, allowing unauthenticated remote attackers to crash the process by sending a crafted ALPN list. This vulnerability affects Nginx and other third-party applications that have compiled wolfSSL 5.8.4 or earlier with ALPN enabled. A patch is available to address this incomplete validation flaw.

Nginx's path traversal vulnerability enables unauthenticated remote attackers to bypass proxy routing controls and access unintended backend resources by exploiting improper normalization of encoded path sequences. The flaw allows attackers to reach protected endpoints and administrative interfaces that should be restricted through the proxy's access controls. A patch is available for this high-severity issue with a CVSS score of 7.5.

Kan, an open-source project management tool, contains a Server-Side Request Forgery (SSRF) vulnerability in its unauthenticated /api/download/attatchment endpoint in versions 0.5.4 and below. Attackers can exploit this to make arbitrary HTTP requests from the server to internal services, cloud metadata endpoints (such as AWS EC2 metadata at 169.254.169.254), or private network resources without any authentication. With a CVSS score of 8.6 (High) reflecting network-based attack vector, low complexity, and no privileges required, this poses significant risk for confidentiality breaches in affected deployments.

An authorization bypass vulnerability in gRPC-Go allows attackers to circumvent path-based access control by sending HTTP/2 requests with malformed :path pseudo-headers that omit the mandatory leading slash (e.g., 'Service/Method' instead of '/Service/Method'). This affects gRPC-Go servers using path-based authorization interceptors like google.golang.org/grpc/authz with deny rules for canonical paths but fallback allow rules. The vulnerability has a CVSS score of 9.1 (Critical) with network-based exploitation requiring no privileges or user interaction, enabling attackers to access restricted services and potentially exfiltrate or modify sensitive data.

Roxy-WI versions prior to 8.2.6.3 contain a command injection vulnerability in the configuration comparison endpoint that allows authenticated users to execute arbitrary system commands on the host server. The flaw stems from unsanitized user input being directly embedded into template strings executed by the application. An attacker with valid credentials can exploit this to achieve full system compromise with high impact on confidentiality, integrity, and availability.

The kube-router proxy module fails to validate Service externalIPs and LoadBalancer IPs against configured IP ranges, allowing namespace-scoped users to bind arbitrary VIPs on all cluster nodes and hijack traffic to critical services like kube-dns. This affects all kube-router v2.x versions including v2.7.1, primarily impacting multi-tenant clusters where untrusted users have Service creation permissions. A detailed proof-of-concept demonstrates single-command cluster DNS takedown and arbitrary VIP binding with traffic redirection to attacker-controlled pods, though EPSS scoring is not available for this recently disclosed vulnerability.

Glances monitoring system allows local attackers with limited privileges to execute arbitrary commands by injecting shell metacharacters into process or container names, which bypass command sanitization in the action execution handler. The vulnerability affects the threshold alert system that dynamically executes administrator-configured shell commands populated with runtime monitoring data. An attacker controlling a process name or container name can manipulate command parsing to break out of intended command boundaries and inject malicious commands.

A critical HTTP Request Smuggling vulnerability exists in Erlang OTP's inets httpd module that allows attackers to desynchronize front-end and back-end servers by exploiting inconsistent Content-Length header parsing. The vulnerability affects Erlang OTP versions from 17.0 through 28.4.0 (inets 5.10 through 9.6.0) and enables attackers to bypass security controls, potentially poisoning web caches or accessing unauthorized resources. While not currently listed in CISA KEV or showing high EPSS scores, the vulnerability has a CVSS 4.0 score of 7.0 and could lead to significant security boundary violations in production environments using affected Erlang-based web services.

Arbitrary code execution in ingress-nginx controllers via malicious rewrite-target annotations allows authenticated attackers to execute commands and exfiltrate cluster secrets.

No authentication is required to exploit this issue, and EPSS analysis indicates a 4.43% probability of exploitation (89th percentile), suggesting moderate real-world risk despite the lack of known public exploits.

The WebP Express plugin for WordPress is vulnerable to information exposure via config files in all versions up to, and including, 0.25.9. This is due to the plugin not properly randomizing the name of the config file to prevent direct access on NGINX. This makes it possible for unauthenticated attackers to extract configuration data.

The SureMail - SMTP and Email Logs Plugin for WordPress is vulnerable to Unrestricted Upload of File with Dangerous Type in versions up to and including 1.9.0. This is due to the plugin's save_file() function in inc/emails/handler/uploads.php which duplicates all email attachments to a web-accessible directory (wp-content/uploads/suremails/attachments/) without validating file extensions or content types. Files are saved with predictable names derived from MD5 hashes of their content. While the plugin attempts to protect this directory with an Apache .htaccess file to disable PHP execution, this protection is ineffective on nginx, IIS, and Lighttpd servers, or on misconfigured Apache installations. This makes it possible for unauthenticated attackers to achieve Remote Code Execution by uploading malicious PHP files through any public form that emails attachments, calculating the predictable filename, and directly accessing the file to execute arbitrary code granted they are exploiting a site running on an affected web server configuration.

Frappe is a full-stack web application framework. Prior to 15.86.0 and 14.99.2, certain requests were vulnerable to path traversal attacks, wherein some files from the server could be retrieved if the full path was known. Sites hosted on Frappe Cloud, and even other setups that are behind a reverse proxy like NGINX are unaffected. This would mainly affect someone directly using werkzeug/gunicorn. In those cases, either an upgrade or changing the setup to use a reverse proxy is recommended. This vulnerability is fixed in 15.86.0 and 14.99.2.
