Mermaid is a JavaScript based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams. An attacker is able to inject arbitrary `CSS` into the generated graph allowing them to change the styling of elements outside of the generated graph, and potentially exfiltrate sensitive information by using specially crafted `CSS` selectors. The following example shows how an attacker can exfiltrate the contents of an input field by bruteforcing the `value` attribute one character at a time. Whenever there is an actual match, an `http` request will be made by the browser in order to "load" a background image that will let an attacker know what's the value of the character. This issue may lead to `Information Disclosure` via CSS selectors and functions able to generate HTTP requests. This also allows an attacker to change the document in ways which may lead a user to perform unintended actions, such as clicking on a link, etc. This issue has been resolved in version 9.1.3. Users are advised to upgrade. Users unable to upgrade should ensure that user input is adequately escaped before embedding it in CSS blocks.

RSA Archer, versions prior to 6.7 P1 (6.7.0.1), contain a URL injection vulnerability. An unauthenticated attacker could potentially exploit this vulnerability by tricking a victim application user to execute malicious JavaScript code on the affected system.

JetBrains TeamCity before 2020.1.2 was vulnerable to URL injection.

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().

A Host Header Injection vulnerability in qdPM 9.1 may allow an attacker to spoof a particular header and redirect users to malicious websites.

Dell Networking X-Series firmware versions prior to 3.0.1.8 contain a host header injection vulnerability. A remote unauthenticated attacker may potentially exploit this vulnerability by injecting arbitrary host header values to poison the web-cache or trigger redirections.

Microsoft Internet Explorer 11 on Windows 10, 1511, and 1606 and Windows Server 2016 does not enforce cross-domain policies, allowing attackers to access information from one domain and inject it into another via a crafted application, aka, "Internet Explorer Elevation of Privilege Vulnerability."

IBM Security Verify (IBM Security Verify Privilege Vault 10.9.66) is vulnerable to link injection. By persuading a victim to click on a specially-crafted URL link, a remote attacker could exploit this vulnerability to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking

An HTTP Host header injection vulnerability exists in YzmCMS V5.3. A malicious user can poison a web cache or trigger redirections.

In Moodle 2.x and 3.x, text injection can occur in email headers, potentially leading to outbound spam.

invenio-app before 1.1.1 allows host header injection.

Machform prior to version 16 is vulnerable to HTTP host header injection due to improperly validated host headers. This could cause a victim to receive malformed content.

An Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') weakness in J-web of Juniper Networks Junos OS leads to buffer overflows, segment faults, or other impacts, which allows an attacker to modify the integrity of the device and exfiltration information from the device without authentication. The weakness can be exploited to facilitate cross-site scripting (XSS), cookie manipulation (modifying session cookies, stealing cookies) and more. This weakness can also be exploited by directing a user to a seemingly legitimate link from the affected site. The attacker requires no special access or permissions to the device to carry out such attacks. This issue affects: Juniper Networks Junos OS: 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S5; 18.3 versions prior to 18.3R2-S4, 18.3R3-S3; 18.4 versions prior to 18.4R2-S5, 18.4R3-S3; 19.1 versions prior to 19.1R2-S2, 19.1R3-S2; 19.2 versions prior to 19.2R1-S5, 19.2R2; 19.3 versions prior to 19.3R3; 19.4 versions prior to 19.4R1-S3, 19.4R2, 19.4R3; 20.1 versions prior to 20.1R1-S2, 20.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 18.1R1.
