Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From version 1.0.0 to before version 2.2.0, the getRedirectURL function in oauth2.go:22-29 constructs the OAuth2 callback URL by concatenating the request's Host header with a fixed path, with zero validation of the Host header. This can result in host header injection. This issue has been patched in version 2.2.0.
CVE-2026-50089 is a medium severity vulnerability in the Aqara IAM/SSO Gateway that allows an open redirect to untrusted sites. This issue is classified as CWE-601 and can be exploited to facilitate phishing attacks by redirecting users to malicious URLs. The vulnerability requires no privileges and user interaction is needed to trigger the redirect. It impacts confidentiality and integrity but not availability.
Umbraco CMS versions prior to 13.14.0 and 17.4.0 contain an open redirect vulnerability in some Surface Controllers that handle member-related operations. These controllers fail to properly validate redirect URLs derived from user-controlled query parameters, allowing malicious redirection. This vulnerability has been addressed in versions 13.14.0 and 17.4.0.
Sensitive Data Exposure vulnerability in Erlang OTP inets (httpc_response module) allows Retrieve Embedded Sensitive Data.
The httpc client forwards the Authorization and Proxy-Authorization request headers to redirect targets without checking whether the redirect crosses an origin boundary. httpc_response:redirect/2 constructs the redirected request by updating only the host field of the header record; all other fields (including authorization and proxy_authorization) are copied verbatim. The redirect target host is never compared against the original host.
autoredirect defaults to true, so this affects all httpc callers that do not explicitly disable automatic redirects.
An attacker who controls a server that the victim contacts via httpc can issue a cross-origin 3xx redirect to a server they also control. The Authorization header (including Basic credentials derived from URL userinfo via httpc_request:handle_user_info/2) is forwarded to the redirect target, allowing credential theft. The same applies to the Proxy-Authorization header.
This vulnerability is associated with program files lib/inets/src/http_client/httpc_response.erl.
This issue affects OTP from OTP 17.0 before OTP 27.3.4.19, OTP 28.5.0.8, and OTP 29.1.2, corresponding to inets from 5.10 before 9.3.2.8, 9.6.2.4, and 9.8.1. Whether OTP before OTP 17.0, corresponding to inets before 5.10, is affected is unknown.
Jenkins 2.567 and earlier, LTS 2.555.2 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins when it contains tab or newline characters between `//`, allowing attackers to perform phishing attacks.
Spring Security's CookieRequestCache and CookieServerRequestCache store the pre-authentication request URL in a browser cookie so that users can be redirected back to their intended destination after a successful login. In affected versions, the full absolute URL is stored in the cookie and is used without validation as the post-login redirect target.
Affected versions:
Spring Security 5.7.0 through 5.7.23; 5.8.0 through 5.8.25; 6.3.0 through 6.3.16; 6.4.0 through 6.4.16; 6.5.0 through 6.5.10; 7.0.0 through 7.0.5.
Spring Security Authorization Server's authorization endpoint performs insufficient validation of the request_uri parameter. An attacker can craft a malicious authorization request containing an invalid request_uri and an arbitrary, unvalidated redirect_uri, which can lead to an Open Redirect vulnerability.
Affected versions:
Spring Security 7.0.0 through 7.0.5.
Spring Authorization Server 1.5.0 through 1.5.7.
Adobe Experience Manager versions 6.5.24, LTS SP1, 2026.04 and earlier are affected by an Improper Redirect (Open Redirect) vulnerability that could result in a Security feature bypass. An attacker could construct a malicious URL that redirects a victim to an attacker-controlled site. Exploitation of this issue requires user interaction in that a victim must click on a malicious link. Scope is changed.
Applications that use GeneralUtility::sanitizeLocalUrl to allow only local URLs are vulnerable to open redirect attacks if the URL is used after it has passed the aforementioned sanitization checks. This enables attackers to redirect users to external content and carry out phishing attacks. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.
CVE-2026-41844 is an open redirect vulnerability in the Spring Framework affecting Spring MVC or Spring WebFlux applications that configure a catch-all mapping ("/**") without explicitly specifying the view name. This allows attackers to craft URLs that cause a 302 redirect to arbitrary external hosts using the redirect: prefix. The vulnerability affects multiple Spring Framework versions from 5.3.0 through 7.0.7. The CVSS score is 4.2, indicating medium severity.
HCL Digital Experience and HCL Digital Experience Compose could be susceptible to Host header injection. An attacker can manipulate the Host header and cause the application to behave in unexpected ways.
authentik is an open-source identity provider. Prior to version 2026.2.3, the WS-Federation provider validates the user-supplied wreply parameter using a raw string prefix check rather than proper URL parsing. An attacker who can craft a login link can supply a wreply value on a different origin that passes the check (e.g.https://portal.example.com.evil.tld/), causing the victim's browser to POST the signed WS-Federation login response to attacker-controlled infrastructure. This issue has been patched in version 2026.2.3.
React Router is a router for React. In versions 7.0.0 through 7.14.0 and 6.7.0 through 6.30.3, certain URLs passed to the redirect function can trigger an open redirect to an external domain due to path values starting with // being reinterpreted as protocol-relative URLs. The level of impact depends on the validation done by the application prior to returning the redirect. This does not impact applications using Declarative Mode (<BrowserRouter>). This is patched in versions 7.14.1 and 6.30.4.
Nextcloud is an open source content collaboration platform. From version 6.1.0 to before version 8.2.2, an attacker can craft links that would redirect users to another website, when the victim uses the attackers link to log in via user OIDC. This issue has been patched in version 8.2.2.
A bug in the login redirect route in Apache Airflow allowed authenticated users to craft URLs that bypassed the `is_safe_url` check, enabling redirection from a trusted Airflow domain to an attacker-controlled origin. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can place Airflow behind a reverse proxy that strips off-domain `next=` query parameters before they reach the login endpoint.
CVE-2026-49380 is an open redirect vulnerability (CWE-601) in the SAML plugin of JetBrains TeamCity versions before 2026.1. The vulnerability allows an attacker to craft a URL that redirects users to an unintended external site. The CVSS score is 3.1, indicating a low severity issue with limited impact. No official patch or remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.
Speakr is a personal, self-hosted web application designed for transcribing audio recordings. Prior to 0.8.20-alpha, the is_safe_url() helper used to validate post-login redirect targets applied urljoin(request.host_url, target) before parsing, while the controller passed the raw target to redirect(). A scheme-relative input such as ////evil.com resolved to a same-host URL during validation but was emitted verbatim in the Location header, where the browser interpreted it as a network-path-relative redirect to an attacker-controlled host. This vulnerability is fixed in 0.8.20-alpha.
CVE-2026-45335 is an Open Redirect vulnerability in the WeGIA web manager for charitable institutions. The flaw exists in versions prior to 3.7.3 within the /WeGIA/controle/control.php endpoint, specifically involving the nextPage parameter when used with certain query parameters. The application does not properly validate or restrict this parameter, allowing attackers to redirect users to arbitrary external sites. This can facilitate phishing, credential theft, malware distribution, and social engineering attacks leveraging the trusted WeGIA domain. The vulnerability has a medium severity rating and a CVSS score of 5.4. It is fixed in version 3.
CVE-2026-49059 is an Open Redirect vulnerability in Facebook for WooCommerce that allows URL redirection to untrusted sites, which can facilitate phishing attacks. The vulnerability affects versions up to 3.7.0. It has a CVSS 3.1 base score of 4.7, indicating medium severity. There is no official patch or remediation level currently provided by the vendor. No known exploits in the wild have been reported.
