CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-27944 Unauthenticated backup download and RCE in Nginx UI before 2.3.3. EPSS 1.0%. PoC available. CRITICAL 9.8 1.0% 70
PoC
CVE-2026-22265 Authenticated command injection in Roxy-WI versions prior to 8.2.8.2 enables attackers to execute arbitrary system commands through improper sanitization of the grep parameter in log viewing functionality. Public exploit code exists for this vulnerability, affecting users managing HAProxy, Nginx, Apache, and Keepalived servers through the web interface. A patch is available in version 8.2.8.2 and later. HIGH 7.5 0.2% 58
PoC
CVE-2026-33494 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. CRITICAL 10.0 0.0% 50
CVE-2026-33502 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. CRITICAL 9.3 3.0% 50
CVE-2026-23837 MyTube self-hosted video downloader has an authorization bypass (CVSS 9.8) that allows unauthenticated access to administrative functions in versions 1.7.65 and prior. CRITICAL 9.8 0.3% 49
CVE-2026-33032 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. CRITICAL 9.8 0.1% 49
No patch
CVE-2026-33026 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. CRITICAL 9.4 0.0% 47
No patch
CVE-2026-34759 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. CRITICAL 9.2 0.1% 46
No patch
CVE-2026-33419 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. CRITICAL 9.1 0.1% 46
No patch
CVE-2026-33186 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. CRITICAL 9.1 0.0% 46
CVE-2026-27811 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. HIGH 8.8 0.2% 44
No patch
CVE-2026-24512 Ingress-nginx controllers are vulnerable to arbitrary code execution through malicious path specifications in Ingress rules, allowing authenticated attackers to inject nginx configuration and execute commands with controller privileges. The vulnerability also enables disclosure of cluster-wide Secrets accessible to the controller. No patch is currently available, and exploitation requires low complexity with only low privileges needed. HIGH 8.8 0.1% 44
CVE-2026-1580 Arbitrary code execution in ingress-nginx controllers via malicious `nginx.ingress.kubernetes.io/auth-method` Ingress annotations allows authenticated attackers to execute commands within the controller context and access cluster-wide Secrets. This vulnerability affects Nginx and Kubernetes deployments where the ingress controller has default cluster-wide Secret access permissions. No patch is currently available. HIGH 8.8 0.0% 44
CVE-2025-15566 A security issue was discovered in ingress-nginx where the `nginx.ingress.kubernetes.io/auth-proxy-set-headers` Ingress annotation can be used to inject configuration into nginx. [CVSS 8.8 HIGH] HIGH 8.8 0.0% 44
No patch
CVE-2026-4342 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. HIGH 8.8 0.0% 44
