| CVE-2026-21762 | 2026-07-17 | N/A | 3.7 LOW | ||
| HCL DevOps Loop is affected by missing HTTP security headers. Missing security headers may reduce browser protections against common web-based attacks such as clickjacking, MIME-type sniffing, and cross-site scripting. | |||||
| CVE-2026-33805 | 1 Fastify | 2 Fastify\/http-proxy, Reply-from | 2026-07-15 | N/A | 8.6 HIGH |
| @fastify/reply-from v12.6.1 and earlier and @fastify/http-proxy v11.4.3 and earlier process the client's Connection header after the proxy has added its own headers via rewriteRequestHeaders. This allows attackers to retroactively strip proxy-added headers from upstream requests by listing them in the Connection header value. Any header added by the proxy for routing, access control, or security purposes can be selectively removed by a client. @fastify/http-proxy is also affected as it delegates to @fastify/reply-from. Upgrade to @fastify/reply-from v12.6.2 or @fastify/http-proxy v11.4.4 or later. | |||||
| CVE-2026-1698 | 1 Arcinfo | 1 Pcvue | 2026-07-09 | N/A | 6.1 MEDIUM |

| The admin panel lacks standard security headers, enabling clickjacking and cross-site scripting attacks. | |||||
| CVE-2026-55791 | 2026-07-02 | N/A | N/A | ||
| Craft CMS is a content management system (CMS). Versions 4.0.0-RC1 and above, prior to 4.18.0 and 5.0.0-RC1, and above, prior to 5.10.0, are vulnerable to Server-Side Request Forgery (SSRF) and Arbitrary JavaScript Injection through the /actions/app/resource-js endpoint. By exploiting the default permissive trustedHosts configuration, an attacker can poison the Host or X-Forwarded-Host header to manipulate the application’s $baseUrl. This bypasses the endpoint’s internal URL validation, forcing the backend Guzzle client to fetch a malicious payload from an attacker-controlled server and reflect it to the client with a Content-Type: application/javascript header. The vulnerability manifests when assetManager.cacheSourcePaths is set to false. This issue has been fixed in versions 4.18.0 and 5.10.0. | |||||
| CVE-2024-51454 | 1 Ibm | 1 Engineering Workflow Management | 2026-06-26 | N/A | 6.5 MEDIUM |
| IBM Engineering Workflow Management 7.0.2 through 7.0.2 Interim Fix 035, 7.0.3 through 7.0.3 Interim Fix 017, and 7.1 through 7.1 Interim Fix 004 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking. | |||||
| CVE-2026-10836 | 2026-06-17 | N/A | N/A | ||
| Improper handling of HTTP headers that allows a remote attacker to manipulate the value of the Host header using specially crafted requests. A successful exploit could result in the generation of manipulated links or responses, potentially leading to limited information disclosure or compromising the integrity of dependent services. | |||||
| CVE-2026-4096 | 1 Ibm | 1 Devops Plan | 2026-06-17 | N/A | 6.5 MEDIUM |
| IBM DevOps Plan 3.0.0 through 3.0.6 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers.

| CVE-2026-48126 | 2026-06-17 | N/A | 8.2 HIGH | ||
| Algernon is a small self-contained pure-Go web server. Prior to 1.17.8, when algernon is started with --domain (or --letsencrypt, which silently turns on --domain at engine/flags.go:372), the request handler resolves the served directory by joining the configured --dir with the value of the client-supplied Host header. The join is performed by filepath.Join with no validation, so a Host: .. header walks one level above the document root. Subsequent file resolution then exposes everything in that parent directory — arbitrary file read, full directory listing, and, if any .lua file is present, server-side Lua execution. This vulnerability is fixed in 1.17.8. | |||||
| CVE-2026-33149 | 1 Tandoor | 1 Recipes | 2026-06-17 | N/A | 8.1 HIGH |
| Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Versions up to and including 2.5.3 set ALLOWED_HOSTS = '*' by default, which causes Django to accept any value in the HTTP Host header without validation. The application uses request.build_absolute_uri() to generate absolute URLs in multiple contexts, including invite link emails, API pagination, and OpenAPI schema generation. An attacker who can send requests to the application with a crafted Host header can manipulate all server-generated absolute URLs. The most critical impact is invite link poisoning: when an admin creates an invite and the application sends the invite email, the link points to the attacker's server instead of the real application. When the victim clicks the link, the invite token is sent to the attacker, who can then use it at the real application. As of time of publication, it is unknown if a patched version is available. | |||||
| CVE-2026-26747 | 1 Monicahq | 1 Monica | 2026-06-17 | N/A | 9.1 CRITICAL |
| A Host Header Poisoning vulnerability exists in Monica 4.1.2 due to improper handling of the HTTP Host header in app/Providers/AppServiceProvider.php, combined with the default misconfiguration where the "app.force_url" is not set and default is "false". The application generates absolute URLs (such as those used in password reset emails) using the user-supplied Host header. This allows remote attackers to poison the password reset link sent to a victim, | |||||
| CVE-2026-26234 | 1 Jung-group | 2 Smart Visu Server, Smart Visu Server Firmware | 2026-06-17 | N/A | 8.8 HIGH |
| JUNG Smart Visu Server 1.1.1050 contains a request header manipulation vulnerability that allows unauthenticated attackers to override request URLs by injecting arbitrary values in the X-Forwarded-Host header. Attackers can manipulate proxied requests to generate tainted responses, enabling cache poisoning, potential phishing, and redirecting users to malicious domains. | |||||
| CVE-2025-70948 | 2026-06-17 | N/A | 9.3 CRITICAL | ||
| A host header injection vulnerability in the mailer component of @perfood/couch-auth v0.26.0 allows attackers to obtain reset tokens and execute an account takeover via spoofing the HTTP Host header. | |||||
| CVE-2025-67724 | 1 Tornadoweb | 1 Tornado | 2026-06-17 | N/A | 5.4 MEDIUM |
| Tornado is a Python web framework and asynchronous networking library. In versions 6.5.2 and below, the supplied reason phrase is used unescaped in HTTP headers (where it could be used for header injection) or in HTML in the default error page (where it could be used for XSS) and can be exploited by passing untrusted or malicious data into the reason argument. Used by both RequestHandler.set_status and tornado.web.HTTPError, the argument is designed to allow applications to pass custom "reason" phrases (the "Not Found" in HTTP/1.1 404 Not Found) to the HTTP status line (mainly for non-standard status codes). This issue is fixed in version 6.5.3. | |||||
| CVE-2025-66485 | 1 Ibm | 1 Aspera Shares | 2026-06-17 | N/A | 5.4 MEDIUM |
| IBM Aspera Shares 1.9.9 through 1.11.0 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking. | |||||
| CVE-2025-64484 | 2026-06-17 | N/A | 8.5 HIGH | ||
| OAuth2-Proxy is an open-source tool that can act as either a standalone reverse proxy or a middleware component integrated into existing reverse proxy or load balancer setups. In versions prior to 7.13.0, all deployments of OAuth2 Proxy in front of applications that normalize underscores to dashes in HTTP headers (e.g., WSGI-based frameworks such as Django, Flask, FastAPI, and PHP applications). Authenticated users can inject underscore variants of X-Forwarded-* headers that bypass the proxy’s filtering logic, potentially escalating privileges in the upstream app. OAuth2 Proxy authentication/authorization itself is not compromised. The problem has been patched with v7.13.0. By default all specified headers will now be normalized, meaning that both capitalization and the use of underscores (_) versus dashes (-) will be ignored when matching headers to be stripped. For example, both `X-Forwarded-For` and `X_Forwarded-for` will now be treated as equivalent and stripped away. For those who have a rational that requires keeping a similar looking header and not stripping it, the maintainers introduced a new configuration field for Headers managed through the AlphaConfig called `InsecureSkipHeaderNormalization`. As a workaround, ensure filtering and processing logic in upstream services don't treat underscores and hyphens in Headers the same way. | |||||
| CVE-2025-64425 | 1 Coollabs | 1 Coolify | 2026-06-17 | N/A | 8.1 HIGH |
| Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. In Coolify versions up to and including v4.0.0-beta.434, an attacker can initiate a password reset for a victim, and modify the host header of the request to a malicious value. The victim will receive a password reset email, with a link to the malicious host. If the victim clicks this link, their reset token is sent to the attacker's server, allowing the attacker to use it to change the victim's password and takeover their account. As of time of publication, it is unclear if a patch is available. | |||||
| CVE-2025-52660 | 1 Hcltech | 1 Aion | 2026-06-17 | N/A | 2.7 LOW |
| HCL AION is affected by an Unrestricted File Upload vulnerability. This can allow malicious file uploads, potentially resulting in unauthorized code execution or system compromise. | |||||
