EUVD-2026-37000

Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded headers from untrusted proxies in certain configuration scenarios. This affects both the WebMVC and WebFlux Gateway Servers. Affected versions: Spring Cloud Gateway 3.1.x fix 3.1.13. Spring Cloud Gateway 4.1.x fix 4.1.13. Spri...

Use of Less Trusted Source

Overview Affected versions of this package are vulnerable to Use of Less Trusted Source. Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded request headers it receives from untrusted proxies to downstream services. Both the WebFlux and WebMVC Gateway Servers process these...

GHSA-3H23-RRPC-3P87 Caddy Defender trusted proxy client IP bypass

Impact Caddy Defender used r.RemoteAddr when evaluating whether a request should be blocked. RemoteAddr is the address of the immediate peer connected to Caddy. In deployments where Caddy is behind a trusted proxy, CDN, or load balancer, the immediate peer is usually the proxy, not the original...

curl: Connection reuse ignores haproxyprotocol and HAPROXY_CLIENT_IP settings, allowing PROXY context to persist across transfers

Summary: libcurl's connection pool match logic does not include the CURLOPTHAPROXYPROTOCOL setting or the CURLOPTHAPROXYCLIENTIP value in its connection match key. Two transfers issued through the same Curleasy or via a shared connection cache CURLLOCKDATACONNECT therefore share one TCP connectio...

User Impersonation

Overview Affected versions of this package are vulnerable to User Impersonation due to the reliance on client-supplied IP address headers such as X-Forwarded-For, X-Real-IP, and True-Client-IP. An attacker can circumvent per-IP rate limiting by supplying arbitrary values in these headers, causing...

CVE-2026-24000

Fleet is open source device management software. Prior to version 4.80.1, Fleet trusted client-supplied IP address headers when determining the source IP for incoming requests. This allowed authenticated and unauthenticated clients to spoof their apparent IP address and bypass per-IP rate limitin...

CVE-2026-46356

Fleet (open-source device management) before v4.80.1 is vulnerable: an IP extraction flaw lets unauthenticated attackers bypass per-IP rate limits by rotating headers like True-Client-IP, X-Real-IP, or X-Forwarded-For, enabling brute-force or credential stuffing on exposed instances. Root cause: ...

CVE-2026-46356 Fleet: IP spoofing allows bypassing API rate limiting

Fleet is open source device management software. Prior to version 4.80.1, a vulnerability in Fleet's IP extraction logic allows unauthenticated attackers to bypass API rate limiting by spoofing client IP headers. This may allow brute-force login attempts or other abuse against Fleet instances...

GHSA-MXMP-WR3W-RVQX Fleet: IP spoofing allows bypassing API rate limiting

Summary A vulnerability in Fleet's IP extraction logic allows unauthenticated attackers to bypass API rate limiting by spoofing client IP headers. This may allow brute-force login attempts or other abuse against Fleet instances exposed to the public internet. Impact Fleet extracted client IP...

CVE-2026-40875 mailcow: dockerized vulnerable to stored XSS in user login history real_rip

mailcow: dockerized is an open source groupware/email suite based on docker. In versions prior to 2026-03b, the user dashboard's "Seen successful connections" login history renders the client IP from login logs without HTML escaping. Because the server trusts the X-Real-IP header as the source IP...
