CVE-2026-54722 Jul 30, 16:26 npm HIGH POC PATCH GHSA This Week

SSRF filter bypass in the dssrf npm library (versions <= 1.0.3) lets attackers defeat the is_url_safe() guard by prefixing a URL with a userinfo component (e.g. http://evil.com@127.0.0.1/). Because remove_at_symbol_in_string() strips the '@' from the raw string before new URL() parses it, the hostname is corrupted into a non-resolving string that passes all internal-IP checks, while an HTTP client fed the original URL still connects to the internal host. Publicly available exploit code exists (working PoC using nock/got in the advisory), though there is no evidence of active exploitation; this vector was missed by the earlier GHSA-8p33-q827-ghj5 fix.

CVE-2026-55723 Jul 15, 14:33 HIGH PATCH This Week

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.

CVE-2026-11311 Jun 17, 14:04 HIGH This Week

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.
