CVE-2026-107369

Improper Validation of Post-Login Redirect URL in nextjs-auth0

The auth0/nextjs-auth0 SDK validates that the returnTo parameter is a same-origin URL. The SDK then stores this value and, in a later step, reconstructs it for the post-authentication redirect. The reconstruction logic can produce a URL that browsers interpret as an absolute or scheme-relative path, leading to a redirect to an unintended domain.

smart-sso through 2.1.1 OAuth2 Authorization Code Theft via Unvalidated redirectUri

smart-sso through 2.1.1 contains an open redirect vulnerability in the /login handler that allows unauthenticated attackers to steal OAuth2 authorization codes by supplying an unvalidated redirectUri parameter. Attackers can send crafted /login links to users with active SSO sessions, then redeem stolen codes at /oauth2/access_token with any valid client credentials to obtain victims' access tokens.

CVE-2026-103523

Thelia v2.6.0 contains an open redirect vulnerability in its address creation workflow. After a user accesses a crafted URL and successfully submits the “Add New Address” form, the application redirects them to the URL specified in the `next` parameter. Because the application does not validate whether the destination belongs to the same origin or an approved allowlist, an attacker can supply an arbitrary external URL and redirect users to an attacker-controlled website.

Backstage: Unauthenticated OAuth account takeover via `redirect_uri` allowlist bypass in `@backstage/plugin-auth-backend`

Backstage is an open framework for building developer portals. Prior to 0.29.2, the experimental dynamic client registration and client ID metadata document features in the @backstage/plugin-auth-backend use full-string matcher.isMatch glob matching for auth.experimentalDynamicClientRegistration.allowedRedirectUriPatterns and the auth.experimentalClientIdMetadataDocuments allowedClientIdPatterns and allowedRedirectUriPatterns options. A hostname wildcard can match across URL component boundaries, allowing an attacker-controlled redirect URI with a trusted hostname suffix in its path to pass the allowlist and receive an OAuth authorization code after a victim completes the flow. Patterns without an explicit protocol can match unintended protocols, and redirect URIs containing embedded credentials are accepted after user information is stripped for matching. The features are experimental and disabled by default; only deployments that enable them and configure custom wildcard-hostname or protocol-less patterns are affected. This issue is first fixed in prerelease version 0.29.2.

CVE-2026-48856

httpc leaks Authorization header to cross-origin redirect targets

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.

Joomla Extension - svenbluege.de - Cross-site scripting and open redirect on the share mini page in Event Gallery extension < 6.6.0

Joomla Extension - svenbluege.de - Cross-site scripting and open redirect on the share mini page in Event Gallery extension < 6.6.0 - The page a shared image link opens (the share mini page of the front end) can link the article the image was shared from when the option "Share article links" is on. It took the address of the article from the shared link and printed it into the page without checking or escaping it; with the link type "Image Page with Redirect" it followed the address at once. A prepared link could therefore run a script in the page, in the session of the visitor who opened it, or send the visitor to another web site. Nothing on the server is changed or read by the server.

Frappe: Open Redirect via Unsanitized OAuth State Param.

Frappe is a full-stack web application framework. Prior to 15.116.0 and 16.29.0, the OAuth login flow uses an unsanitized client-controlled state parameter to select post-authentication navigation, allowing a crafted state value to redirect a user to an attacker-chosen location. This issue is fixed in versions 15.116.0 and 16.29.0.

AdonisJS: Unencoded route parameters can produce open redirects

AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. Prior to 8.2.3 and 9.3.0, AdonisJS HTTP Server inserts route parameter values into URLs without encodeURIComponent in the shared createURL() helper used by Router.makeUrl() and Response.redirect().toRoute(). If an application places attacker-controlled data in a dynamic first path segment and uses the generated route URL as a redirect destination, a value beginning with a slash can produce a scheme-relative external URL. Wildcard parameters are affected by the same missing encoding, while APIs intentionally accepting complete redirect URLs are not affected. An attacker can redirect users from a trusted application to an attacker-controlled site, facilitating phishing or abuse of authentication and OAuth flows. This issue is fixed in versions 8.2.3 and 9.3.0.

HoloViz Panel from 1.2.2 before 1.9.0 contains an open redirect vulnerability in panel/auth.py that allows remote attackers to redirect users by supplying an unvalidated next query parameter. BasicLoginHandler and PasswordLoginHandler store the parameter in a next_url cookie, so crafted login links send victims to attacker-controlled external sites after successful login.

TinaCMS admin preview iframe loads an attacker-controlled origin from the URL fragment

Tina is a headless content management system. Prior to tinacms 3.14.0 and @tinacms/app 2.5.14, the /~/* admin preview route in packages/tinacms/src/admin/index.tsx can turn an attacker-controlled hash-router splat into an off-origin iframe URL through packages/@tinacms/app/src/preview.tsx, while packages/@tinacms/app/src/lib/preview-origin.ts derives expectedOrigin from that same URL for the GraphQL message channel in packages/@tinacms/app/src/lib/graphql-reducer.ts. An unauthenticated attacker can send a crafted link to a signed-in editor, cause the admin to frame an attacker origin, and have that frame treated as the trusted preview. The attacker-controlled frame can submit GraphQL reads or mutations that the admin executes with the editor credentials, exposing or modifying protected content. This issue is fixed in tinacms 3.14.0 and @tinacms/app 2.5.14.
