| 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-2023-23936 | 1 Nodejs | 2 Node.js, Undici | 2026-06-17 | N/A | 6.5 MEDIUM |
| Undici is an HTTP/1.1 client for Node.js. Starting with version 2.0.0 and prior to version 5.19.1, the undici library does not protect `host` HTTP header from CRLF injection vulnerabilities. This issue is patched in Undici v5.19.1. As a workaround, sanitize the `headers.host` string before passing to undici. | |||||
| CVE-2023-0040 | 1 Asynchttpclient Project | 1 Async-http-client | 2026-06-17 | N/A | 7.5 HIGH |
| Versions of Async HTTP Client prior to 1.13.2 are vulnerable to a form of targeted request manipulation called CRLF injection. This vulnerability was the result of insufficient validation of HTTP header field values before sending them to the network. Users are vulnerable if they pass untrusted data into HTTP header field values without prior sanitisation. Common use-cases here might be to place usernames from a database into HTTP header fields. This vulnerability allows attackers to inject new HTTP header fields, or entirely new requests, into the data stream. This can cause requests to be understood very differently by the remote server than was intended. In general, this is unlikely to result in data disclosure, but it can result in a number of logical errors and other misbehaviours. | |||||
| 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-2022-31014 | 1 Nextcloud | 1 Nextcloud Server | 2026-06-17 | 3.5 LOW | 5.4 MEDIUM |
| Nextcloud server is an open source personal cloud server. Affected versions were found to be vulnerable to SMTP command injection. The impact varies based on which commands are supported by the backend SMTP server. However, the main risk here is that the attacker can then hijack an already-authenticated SMTP session and run arbitrary SMTP commands as the email user, such as sending emails to other users, changing the FROM user, and so on. As before, this depends on the configuration of the server itself, but newlines should be sanitized to mitigate such arbitrary SMTP command injection. It is recommended that the Nextcloud Server is upgraded to 22.2.8 , 23.0.5 or 24.0.1. There are no known workarounds 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-2021-31164 | 1 Apache | 1 Unomi | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| Apache Unomi prior to version 1.5.5 allows CRLF log injection because of the lack of escaping in the log statements. | |||||
| CVE-2020-3246 | 1 Cisco | 1 Umbrella | 2026-06-17 | 4.3 MEDIUM | 4.3 MEDIUM |
| A vulnerability in the web server of Cisco Umbrella could allow an unauthenticated, remote attacker to perform a carriage return line feed (CRLF) injection attack against a user of an affected service. The vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user to access a crafted URL. A successful exploit could allow the attacker to inject arbitrary HTTP headers into valid HTTP responses sent to the browser of the user. | |||||
| CVE-2020-15111 | 1 Gofiber | 1 Fiber | 2026-06-17 | 5.8 MEDIUM | 4.2 MEDIUM |
| In Fiber before version 1.12.6, the filename that is given in c.Attachment() (https://docs.gofiber.io/ctx#attachment) is not escaped, and therefore vulnerable for a CRLF injection attack. I.e. an attacker could upload a custom filename and then give the link to the victim. With this filename, the attacker can change the name of the downloaded file, redirect to another site, change the authorization header, etc. A possible workaround is to serialize the input before passing it to ctx.Attachment(). | |||||
| 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. | |||||
| CVE-2019-9947 | 1 Python | 1 Python | 2026-06-17 | 4.3 MEDIUM | 6.1 MEDIUM |
| An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.3. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the path component of a URL that lacks a ? character) followed by an HTTP header or a Redis command.
