| CVE-2024-51501 | 2026-06-17 | N/A | N/A | ||
| Refit is an automatic type-safe REST library for .NET Core, Xamarin and .NET The various header-related Refit attributes (Header, HeaderCollection and Authorize) are vulnerable to CRLF injection. The way HTTP headers are added to a request is via the `HttpHeaders.TryAddWithoutValidation` method. This method does not check for CRLF characters in the header value. This means that any headers added to a refit request are vulnerable to CRLF-injection. In general, CRLF-injection into a HTTP header (when using HTTP/1.1) means that one can inject additional HTTP headers or smuggle whole HTTP requests. If an application using the Refit library passes a user-controllable value through to a header, then that application becomes vulnerable to CRLF-injection. This is not necessarily a security issue for a command line application like the one above, but if such code were present in a web application then it becomes vulnerable to request splitting (as shown in the PoC) and thus Server Side Request Forgery. Strictly speaking this is a potential vulnerability in applications using Refit and not in Refit itself. This issue has been addressed in release versions 7.2.22 and 8.0.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability. | |||||

| CVE-2024-45597 | 1 Pluto-lang | 1 Pluto | 2026-06-17 | N/A | 5.3 MEDIUM |
| Pluto is a superset of Lua 5.4 with a focus on general-purpose programming. Scripts passing user-controlled values to http.request header values are affected. An attacker could use this to send arbitrary requests, potentially leveraging authentication tokens provided in the same headers table. | |||||
| CVE-2024-45302 | 1 Restsharp | 1 Restsharp | 2026-06-17 | N/A | 6.1 MEDIUM |
| RestSharp is a Simple REST and HTTP API Client for .NET. The second argument to `RestRequest.AddHeader` (the header value) is vulnerable to CRLF injection. The same applies to `RestRequest.AddOrUpdateHeader` and `RestClient.AddDefaultHeader`. The way HTTP headers are added to a request is via the `HttpHeaders.TryAddWithoutValidation` method which does not check for CRLF characters in the header value. This means that any headers from a `RestSharp.RequestHeaders` object are added to the request in such a way that they are vulnerable to CRLF-injection. In general, CRLF-injection into a HTTP header (when using HTTP/1.1) means that one can inject additional HTTP headers or smuggle whole HTTP requests. If an application using the RestSharp library passes a user-controllable value through to a header, then that application becomes vulnerable to CRLF-injection. This is not necessarily a security issue for a command line application like the one above, but if such code were present in a web application then it becomes vulnerable to request splitting (as shown in the PoC) and thus Server Side Request Forgery. Strictly speaking this is a potential vulnerability in applications using RestSharp, not in RestSharp itself, but I would argue that at the very least there needs to be a warning about this behaviour in the RestSharp documentation. RestSharp has addressed this issue in version 112.0.0. All users are advised to upgrade. There are no known workarounds for this vulnerability. | |||||
| CVE-2024-40324 | 1 Datex-soft | 1 E-staff | 2026-06-17 | N/A | 5.4 MEDIUM |
| A CRLF injection vulnerability in E-Staff v5.1 allows attackers to insert Carriage Return (CR) and Line Feed (LF) characters into input fields, leading to HTTP response splitting and header manipulation. | |||||
| CVE-2024-36459 | 2026-06-17 | N/A | N/A | ||
| A CRLF cross-site scripting vulnerability has been identified in certain configurations of the SiteMinder Web Agent for IIS Web Server and SiteMinder Web Agent for Domino Web Server. As a result, an attacker can execute arbitrary Javascript code in a client browser. | |||||
| CVE-2024-32986 | 2026-06-17 | N/A | 9.6 CRITICAL | ||
| PWAsForFirefox is a tool to install, manage and use Progressive Web Apps (PWAs) in Mozilla Firefox. Due to improper sanitization of web app properties (such as name, description, shortcuts), web apps were able to inject additional lines into XDG Desktop Entries (on Linux) and `AppInfo.ini` (on PortableApps.com). This allowed malicious web apps to introduce keys like `Exec`, which could run arbitrary code when the affected web app was launched. This vulnerability affects all Linux and PortableApps.com users of all PWAsForFirefox versions up to (excluding) 2.12.0. Windows and macOS users are not affected. This vulnerability has been fixed in commit `9932d4b` which has been included in release in v2.12.0. The main fix is implemented in the native part, but the extension also contains additional fixes. All Linux and PortableApps.com users are advised to update to this version as soon as possible. It is also recommended for Windows and macOS users to update to this version, as it contains additional fixes related to properties sanitization. There are no known workarounds for this vulnerability. | |||||
| CVE-2024-1226 | 2026-06-17 | N/A | 7.5 HIGH | ||
| The software does not neutralize or incorrectly neutralizes certain characters before the data is included in outgoing HTTP headers. The inclusion of invalidated data in an HTTP header allows an attacker to specify the full HTTP response represented by the browser. An attacker could control the response and craft attacks such as cross-site scripting and cache poisoning attacks. | |||||

| CVE-2023-26130 | 1 Cpp-httplib Project | 1 Cpp-httplib | 2026-06-17 | N/A | 7.5 HIGH |
| Versions of the package yhirose/cpp-httplib before 0.12.4 are vulnerable to CRLF Injection when untrusted user input is used to set the content-type header in the HTTP .Patch, .Post, .Put and .Delete requests. This can lead to logical errors and other misbehaviors. **Note:** This issue is present due to an incomplete fix for [CVE-2020-11709](https://security.snyk.io/vuln/SNYK-UNMANAGED-YHIROSECPPHTTPLIB-2366507). | |||||
| CVE-2022-50682 | 1 Kentico | 1 Xperience | 2026-06-17 | N/A | 6.5 MEDIUM |
| A CRLF injection vulnerability in Kentico Xperience allows attackers to manipulate URL query string redirects via improper encoding in the routing engine. This could enable header injection and potentially facilitate further web application attacks. | |||||
| CVE-2022-35948 | 1 Nodejs | 1 Undici | 2026-06-17 | N/A | 5.3 MEDIUM |
| undici is an HTTP/1.1 client, written from scratch for Node.js.`=< undici@5.8.0` users are vulnerable to _CRLF Injection_ on headers when using unsanitized input as request headers, more specifically, inside the `content-type` header. Example: ``` import { request } from 'undici' const unsanitizedContentTypeInput = 'application/json\r\n\r\nGET /foo2 HTTP/1.1' await request('http://localhost:3000, { method: 'GET', headers: { 'content-type': unsanitizedContentTypeInput }, }) ``` The above snippet will perform two requests in a single `request` API call: 1) `http://localhost:3000/` 2) `http://localhost:3000/foo2` This issue was patched in Undici v5.8.1. Sanitize input when sending content-type headers using user input as a workaround. | |||||
| CVE-2022-31150 | 1 Nodejs | 1 Undici | 2026-06-17 | N/A | 5.3 MEDIUM |
| undici is an HTTP/1.1 client, written from scratch for Node.js. It is possible to inject CRLF sequences into request headers in undici in versions less than 5.7.1. A fix was released in version 5.8.0. Sanitizing all HTTP headers from untrusted sources to eliminate `\r\n` is a workaround for this issue. | |||||
| CVE-2022-0666 | 1 Microweber | 1 Microweber | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |

| CVE-2021-39172 | 1 Catchethq | 1 Catchet | 2026-06-17 | 6.5 MEDIUM | 8.8 HIGH |
| Cachet is an open source status page system. Prior to version 2.5.1, authenticated users, regardless of their privileges (User or Admin), can exploit a new line injection in the configuration edition feature (e.g. mail settings) and gain arbitrary code execution on the server. This issue was addressed in version 2.5.1 by improving `UpdateConfigCommandHandler` and preventing the use of new lines characters in new configuration values. As a workaround, only allow trusted source IP addresses to access to the administration dashboard. | |||||
| CVE-2020-11078 | 3 Debian, Fedoraproject, Httplib2 Project | 3 Debian Linux, Fedora, Httplib2 | 2026-06-17 | 4.3 MEDIUM | 6.8 MEDIUM |
| In httplib2 before version 0.18.0, an attacker controlling unescaped part of uri for `httplib2.Http.request()` could change request headers and body, send additional hidden requests to same server. This vulnerability impacts software that uses httplib2 with uri constructed by string concatenation, as opposed to proper urllib building with escaping. This has been fixed in 0.18.0. | |||||
