When the default servlet in Apache Tomcat versions 9.0.0.M1 to 9.0.11, 8.5.0 to 8.5.33 and 7.0.23 to 7.0.90 returned a redirect to a directory (e.g. redirecting to '/foo/' when the user requested '/foo') a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice.

In WordPress before 4.7.5, there is improper handling of post meta data values in the XML-RPC API.

Insufficient policy enforcement in Resource Timing API in Google Chrome prior to 63.0.3239.84 allowed a remote attacker to infer browsing history by triggering a leaked cross-origin URL via a crafted HTML page.

Confirmation forms in Drupal 7.x before 7.52 make it easier for remote authenticated users to conduct open redirect attacks via unspecified vectors.

mod_auth_openidc is an OpenID Certified™ authentication and authorization module for the Apache 2.x HTTP server. Versions prior to 2.4.12.2 are vulnerable to Open Redirect. When providing a logout parameter to the redirect URI, the existing code in oidc_validate_redirect_url() does not properly check for URLs that start with /\t, leading to an open redirect. This issue has been patched in version 2.4.12.2. Users unable to upgrade can mitigate the issue by configuring mod_auth_openidc to only allow redirection when the destination matches a given regular expression with OIDCRedirectURLsAllowed.

In affected versions of WordPress, due to an issue in wp_validate_redirect() and URL sanitization, an arbitrary external link can be crafted leading to unintended/open redirect when clicked. This has been patched in version 5.4.2, along with all the previously affected versions via a minor release (5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34).

A flaw was found in Yelp. The Gnome user help application allows the help document to execute arbitrary scripts. This vulnerability allows malicious users to input help documents, which may exfiltrate user files to an external environment.

URL Redirection to Untrusted Site ('Open Redirect') vulnerability in FORM authentication feature Apache Tomcat.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through 10.0.12, from 9.0.0-M1 through 9.0.79 and from 8.5.0 through 8.5.92. Older, EOL versions may also be affected. The vulnerability is limited to the ROOT (default) web application.

An issue was discovered in certain Apple products. iOS before 11.2 is affected. Safari before 11.0.2 is affected. iCloud before 7.2 on Windows is affected. iTunes before 12.7.2 on Windows is affected. tvOS before 11.2 is affected. watchOS before 4.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to spoof user-interface information (about whether the entire content is derived from a valid TLS session) via a crafted web site that sends a 401 Unauthorized redirect.

Open redirect vulnerability in Joomla! CMS 3.0.0 through 3.4.1.

Open redirect vulnerability in Xsuite 2.4.4.5 and earlier allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the redirurl parameter.

After logging into the portal, the logout jsp page redirects the browser back to the login page after. It is feasible for malicious users to redirect the browser to an unintended web page in Apache jUDDI 3.1.2, 3.1.3, 3.1.4, and 3.1.5 when utilizing the portlets based user interface also known as 'Pluto', 'jUDDI Portal', 'UDDI Portal' or 'uddi-console'. User session data, credentials, and auth tokens are cleared before the redirect.

An issue was discovered in Verint Impact 360 15.1. At wfo/control/signin, the rd parameter can accept a URL, to which users will be redirected after a successful login. In conjunction with CVE-2019-12784, this can be used by attackers to "crowdsource" bruteforce login attempts on the target site, allowing them to guess and potentially compromise valid credentials without ever sending any traffic from their own machine to the target site.

mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions prior to 2.4.9, `oidc_validate_redirect_url()` does not parse URLs the same way as most browsers do. As a result, this function can be bypassed and leads to an Open Redirect vulnerability in the logout functionality. This bug has been fixed in version 2.4.9 by replacing any backslash of the URL to redirect with slashes to address a particular breaking change between the different specifications (RFC2396 / RFC3986 and WHATWG). As a workaround, this vulnerability can be mitigated by configuring `mod_auth_openidc` to only allow redirection whose destination matches a given regular expression.

Open redirect vulnerability in Cybozu Remote Service 3.0.0 to 3.1.9 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.

Authenticate/SWT in Progress Sitefinity 9.1 has an open redirect issue in which an authentication token is sent to the redirection target, if the target is specified using a certain %40 syntax. This is fixed in 10.1.

The Python "Flask-Security-Too" package is used for adding security features to your Flask application. It is an is an independently maintained version of Flask-Security based on the 3.0.0 version of Flask-Security. All versions of Flask-Security-Too allow redirects after many successful views (e.g. /login) by honoring the ?next query param. There is code in FS to validate that the url specified in the next parameter is either relative OR has the same netloc (network location) as the requesting URL. This check utilizes Pythons urlsplit library. However many browsers are very lenient on the kind of URL they accept and 'fill in the blanks' when presented with a possibly incomplete URL. As a concrete example - setting http://login?next=\\\github.com will pass FS's relative URL check however many browsers will gladly convert this to http://github.com. Thus an attacker could send such a link to an unwitting user, using a legitimate site and have it redirect to whatever site they want. This is considered a low severity due to the fact that if Werkzeug is used (which is very common with Flask applications) as the WSGI layer, it by default ALWAYS ensures that the Location header is absolute - thus making this attack vector mute. It is possible for application writers to modify this default behavior by setting the 'autocorrect_location_header=False`.

Products.isurlinportal is a replacement for isURLInPortal method in Plone. Versions of Products.isurlinportal prior to 1.2.0 have an Open Redirect vulnerability. Various parts of Plone use the 'is url in portal' check for security, mostly to see if it is safe to redirect to a url. A url like `https://example.org` is not in the portal. The url `https:example.org` without slashes is considered to be in the portal. When redirecting, some browsers go to `https://example.org`, others give an error. Attackers may use this to redirect victims to their site, especially as part of a phishing attack. The problem has been patched in Products.isurlinportal 1.2.0.

URL redirection vulnerability in SAP's Startup Service, SAP KERNEL 32 NUC, SAP KERNEL 32 Unicode, SAP KERNEL 64 NUC, SAP KERNEL 64 Unicode 7.21, 7.21EXT, 7.22 and 7.22EXT; SAP KERNEL 7.21, 7.22, 7.45, 7.49 and 7.52, that allows an attacker to redirect users to a malicious site.

PowerMux is a drop-in replacement for Go's http.ServeMux. In PowerMux versions prior to 1.1.1, attackers may be able to craft phishing links and other open redirects by exploiting the trailing slash redirection feature. This may lead to users being redirected to untrusted sites after following an attacker crafted link. The issue is resolved in v1.1.1. There are no existing workarounds.

Read the Docs before 3.5.1 has an Open Redirect if certain user-defined redirects are used. This affects private instances of Read the Docs (in addition to the public readthedocs.org web sites).

Tenancy multi-tenant is an open source multi-domain controller for the Laravel web framework. In some situations, it is possible to have open redirects where users can be redirected from your site to any other site using a specially crafted URL. This is only the case for installations where the default Hostname Identification is used and the environment uses tenants that have `force_https` set to `true` (default: `false`). Version 5.7.2 contains the relevant patches to fix this bug. Stripping the URL from special characters to prevent specially crafted URL's from being redirected to. As a work around users can set the `force_https` to every tenant to `false`, however this may degrade connection security.

Prometheus is an open-source monitoring system and time series database. In 2.23.0, Prometheus changed its default UI to the New ui. To ensure a seamless transition, the URL's prefixed by /new redirect to /. Due to a bug in the code, it is possible for an attacker to craft an URL that can redirect to any other URL, in the /new endpoint. If a user visits a prometheus server with a specially crafted address, they can be redirected to an arbitrary URL. The issue was patched in the 2.26.1 and 2.27.1 releases. In 2.28.0, the /new endpoint will be removed completely. The workaround is to disable access to /new via a reverse proxy in front of Prometheus.

The ChangeSharedFilterOwner resource in Jira before version 7.13.6, from version 8.0.0 before version 8.2.3, and from version 8.3.0 before version 8.3.2 allows remote attackers to attack users, in some cases be able to obtain a user's Cross-site request forgery (CSRF) token, via a open redirect vulnerability.

A vulnerability was found in Moodle 3.7 to 3.7.1, 3.6 to 3.6.5, 3.5 to 3.5.7 and earlier unsupported versions, where the mobile launch endpoint contained an open redirect in some circumstances, which could result in a user's mobile access token being exposed. (Note: This does not affect sites with a forced URL scheme configured, mobile service disabled, or where the mobile app login method is "via the app").

Elgg before 1.12.18 and 2.3.x before 2.3.11 has an open redirect.

In Rockwell Automation MicroLogix 1400 Controllers Series A, All Versions Series B, v15.002 and earlier, MicroLogix 1100 Controllers v14.00 and earlier, CompactLogix 5370 L1 controllers v30.014 and earlier, CompactLogix 5370 L2 controllers v30.014 and earlier, CompactLogix 5370 L3 controllers (includes CompactLogix GuardLogix controllers) v30.014 and earlier, an open redirect vulnerability could allow a remote unauthenticated attacker to input a malicious link to redirect users to a malicious site that could run or download arbitrary malware on the user’s machine.

A spoofing vulnerability exists in ASP.NET Core that could lead to an open redirect, aka 'ASP.NET Core Spoofing Vulnerability'.

When you visit a page where you need to login, Plone 2.5-5.1rc1 sends you to the login form with a 'came_from' parameter set to the previous url. After you login, you get redirected to the page you tried to view before. An attacker might try to abuse this by letting you click on a specially crafted link. You would login, and get redirected to the site of the attacker, letting you think that you are still on the original Plone site. Or some javascript of the attacker could be executed. Most of these types of attacks are already blocked by Plone, using the `isURLInPortal` check to make sure we only redirect to a page on the same Plone site. But a few more ways of tricking Plone into accepting a malicious link were discovered, and fixed with this hotfix.

All versions of the HTTPie package prior to version 1.0.3 are vulnerable to Open Redirect that allows an attacker to write an arbitrary file with supplied filename and content to the current directory, by redirecting a request from HTTP to a crafted URL pointing to a server in his or hers control.

By linking to a specific url in Plone 2.5-5.1rc1 with a parameter, an attacker could send you to his own website. On its own this is not so bad: the attacker could more easily link directly to his own website instead. But in combination with another attack, you could be sent to the Plone login form and login, then get redirected to the specific url, and then get a second redirect to the attacker website. (The specific url can be seen by inspecting the hotfix code, but we don't want to make it too easy for attackers by spelling it out here.)

In Jupyter Notebook before 5.7.8, an open redirect can occur via an empty netloc. This issue exists because of an incomplete fix for CVE-2019-10255.

An Open Redirect vulnerability for all browsers in Jupyter Notebook before 5.7.7 and some browsers (Chrome, Firefox) in JupyterHub before 0.9.5 allows crafted links to the login page, which will redirect to a malicious site after successful login. Servers running on a base_url prefix are not affected.

Babel: Multilingual site Babel All is affected by: Open Redirection. The impact is: Redirection to any URL, which is supplied to redirect.php in a "newurl" parameter. The component is: redirect.php. The attack vector is: The victim must open a link created by an attacker. Attacker may use any legitimate site using Babel to redirect user to a URL of his/her choosing.
