| CVE-2025-4366 | 1 Cloudflare | 1 Pingora | 2026-06-17 | N/A | 6.1 MEDIUM |
| A request smuggling vulnerability identified within Pingora’s proxying framework, pingora-proxy, allows malicious HTTP requests to be injected via manipulated request bodies on cache HITs, leading to unauthorized request execution and potential cache poisoning. Fixed in: https://github.com/cloudflare/pingora/commit/fda3317ec822678564d641e7cf1c9b77ee3759ff https://github.com/cloudflare/pingora/commit/fda3317ec822678564d641e7cf1c9b77ee3759ff Impact: The issue could lead to request smuggling in cases where Pingora’s proxying framework, pingora-proxy, is used for caching allowing an attacker to manipulate headers and URLs in subsequent requests made on the same HTTP/1.1 connection. | |||||
| CVE-2025-49826 | 1 Vercel | 1 Next.js | 2026-06-17 | N/A | 7.5 HIGH |
| Next.js is a React framework for building full-stack web applications. From versions 15.0.4-canary.51 to before 15.1.8, a cache poisoning bug leading to a Denial of Service (DoS) condition was found in Next.js. This issue does not impact customers hosted on Vercel. Under certain conditions, this issue may allow a HTTP 204 response to be cached for static pages, leading to the 204 response being served to all users attempting to access the page. This issue has been addressed in version 15.1.8. | |||||
| CVE-2025-49005 | 1 Vercel | 2 Next.js, Vercel | 2026-06-17 | N/A | 3.7 LOW |
| Next.js is a React framework for building full-stack web applications. In Next.js App Router from 15.3.0 to before 15.3.3 and Vercel CLI from 41.4.1 to 42.2.0, a cache poisoning vulnerability was found. The issue allowed page requests for HTML content to return a React Server Component (RSC) payload instead under certain conditions. When deployed to Vercel, this would only impact the browser cache, and would not lead to the CDN being poisoned. When self-hosted and deployed externally, this could lead to cache poisoning if the CDN does not properly distinguish between RSC / HTML in the cache keys. This issue has been resolved in Next.js 15.3.3. | |||||
| CVE-2025-47905 | 2026-06-17 | N/A | 5.4 MEDIUM | ||
| Varnish Cache before 7.6.3 and 7.7 before 7.7.1, and Varnish Enterprise before 6.0.13r14, allow client-side desync via HTTP/1 requests, because the product incorrectly permits CRLF to be skipped to delimit chunk boundaries. | |||||
| CVE-2025-43859 | 2026-06-17 | N/A | 9.1 CRITICAL | ||
| h11 is a Python implementation of HTTP/1.1. Prior to version 0.16.0, a leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. This issue has been patched in version 0.16.0. Since exploitation requires the combination of buggy h11 with a buggy (reverse) proxy, fixing either component is sufficient to mitigate this issue. | |||||
| CVE-2025-41235 | 2026-06-17 | N/A | 8.6 HIGH | ||
| Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded headers from untrusted proxies. | |||||
| CVE-2025-41082 | 2026-06-17 | N/A | N/A | ||
| Illegal HTTP request traffic vulnerability (CL.0) in Altitude Communication Server, caused by inconsistent analysis of multiple HTTP requests over a single Keep-Alive connection using Content-Length headers. This can cause a desynchronization of requests between frontend and backend servers, which could allow request hiding, cache poisoning or security bypass. | |||||
| CVE-2025-32094 | 2026-06-17 | N/A | 4.0 MEDIUM | ||
| An issue was discovered in Akamai Ghost, as used for the Akamai CDN platform before 2025-03-26. Under certain circumstances, a client making an HTTP/1.x OPTIONS request with an "Expect: 100-continue" header, and using obsolete line folding, can lead to a discrepancy in how two in-path Akamai servers interpret the request, allowing an attacker to smuggle a second request in the original request body. | |||||
| CVE-2025-31958 | 1 Hcltech | 1 Bigfix Service Management | 2026-06-17 | N/A | 3.7 LOW |
| HCL BigFix Service Management is susceptible to HTTP Request Smuggling. HTTP request smuggling vulnerabilities arise when websites route HTTP requests through web servers with inconsistent HTTP parsing. HTTP Smuggling exploits inconsistencies in request parsing between front-end and back-end servers, allowing attackers to bypass security controls and perform attacks like cache poisoning or request hijacking. | |||||
| CVE-2025-31137 | 2026-06-17 | N/A | 7.5 HIGH | ||
| React Router is a multi-strategy router for React bridging the gap from React 18 to React 19. There is a vulnerability in Remix/React Router that affects all Remix 2 and React Router 7 consumers using the Express adapter. Basically, this vulnerability allows anyone to spoof the URL used in an incoming Request by putting a URL pathname in the port section of a URL that is part of a Host or X-Forwarded-Host header sent to a Remix/React Router request handler. This issue has been patched and released in Remix 2.16.3 and React Router 7.4.1. | |||||
| CVE-2025-30346 | 2 Varnish-software, Varnish Cache Project | 2 Varnish Enterprise, Varnish Cache | 2026-06-17 | N/A | 5.4 MEDIUM |
| Varnish Cache before 7.6.2 and Varnish Enterprise before 6.0.13r10 allow client-side desync via HTTP/1 requests. | |||||
| CVE-2025-29904 | 1 Jetbrains | 1 Ktor | 2026-06-17 | N/A | 5.3 MEDIUM |
| In JetBrains Ktor before 3.1.1 an HTTP Request Smuggling was possible | |||||
| CVE-2025-23167 | 2026-06-17 | N/A | 6.5 MEDIUM | ||
| A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using `\r\n\rX` instead of the required `\r\n\r\n`. This inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests. The issue was resolved by upgrading `llhttp` to version 9, which enforces correct header termination. Impact: * This vulnerability affects only Node.js 20.x users prior to the `llhttp` v9 upgrade. | |||||
| CVE-2025-1867 | 2026-06-17 | N/A | N/A | ||
| Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in ithewei libhv allows HTTP Response Smuggling.This issue affects libhv: through 1.3.3. | |||||
| CVE-2025-1386 | 1 Clickhouse | 1 Ch | 2026-06-17 | N/A | 4.9 MEDIUM |
| When using the ch-go library, under a specific condition when the query includes a large, uncompressed malicious external data, it is possible for an attacker in control of such data to smuggle another query packet into the connection stream. | |||||
| CVE-2025-12874 | 2026-06-17 | N/A | N/A | ||
| Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Quest Coexistence Manager for Notes (Free/Busy Connector modules) allows HTTP Request Smuggling via the Content-Length-Transfer-Encoding (CL.TE) attack vector. This could allow an attacker to bypass access controls, poison web caches, hijack sessions, or trigger unintended internal requests. This issue affects Coexistence Manager for Notes 3.8.2045. Other versions may also be affected. | |||||
| CVE-2025-12811 | 2026-06-17 | N/A | N/A | ||
| Improper Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') in Delinea Inc. Cloud Suite and Privileged Access Service. If you're not using the latest Server Suite agents, this fix requires that you upgrade to Server Suite 2023.1 (agent 6.0.1) or later. * If you cannot upgrade to Release 2023.1 (agent version 6.0.1) or later, you can choose one of the following versions: * Server Suite release 2023.0.5 (agent version 6.0.0-158) * Server Suite release 2022.1.10 (agent version 5.9.1-337) | |||||
| CVE-2025-12642 | 1 Lighttpd | 1 Lighttpd | 2026-06-17 | N/A | 9.1 CRITICAL |
| lighttpd1.4.80 incorrectly merged trailer fields into headers after http request parsing. This behavior can be exploited to conduct HTTP Header Smuggling attacks. Successful exploitation may allow an attacker to: * Bypass access control rules * Inject unsafe input into backend logic that trusts request headers * Execute HTTP Request Smuggling attacks under some conditions This issue affects lighttpd1.4.80 | |||||
