Technical description

URL Redirection to Untrusted Site ('Open Redirect') vulnerability in phoenixframework phoenix_live_view allows an attacker to send a victim's browser to an origin of the attacker's choosing via a :to value containing ASCII tab, LF or CR. redirect/2 validates :to through the private validate_local_url!/2 in lib/phoenix_live_view.ex, which is intended to guarantee the target is a path within the application. It rejects a leading // and any backslash, but not ASCII tab, LF or CR. Browsers strip those three characters before parsing a URL, so a value such as /<TAB>/example.com passes validation as a path and is then resolved as the scheme-relative URL //example.com. The live navigation functions share the guard but are not affected, because the client expands their target against the current origin. push_patch/2 is also affected before 0.7.0, which is when that expansion was added. This issue affects phoenix_live_view: from 0.5.0 before 1.0.19, from 1.1.0-rc.0 before 1.1.33, and from 1.2.0-rc.0 before 1.2.9.

——4Home Assistant is open source home automation software focused on local control and privacy. Prior to 2026.6.1, the Android Companion app is vulnerable to an open redirect. The app passes the URL fragment from a homeassistant://invite deep link into the onboarding flow without ever displaying the destination hostname. Because no screen in the invitation or onboarding flow shows the parsed server URL before onboarding commits to it, a victim has no way to distinguish a legitimate invite from a malicious one. An attacker can craft an invite so that a single tap on the legitimate-looking "Connect to my Home Assistant server" button opens their /auth/authorize endpoint in the URL-less onboarding WebView, presenting a look-alike login page that captures the victim's credentials. Since invitations are intended to onboard brand-new users, targets are especially unlikely to notice the substitution. This issue is fixed in version 2026.6.1.3d CVE-2026-54215—

——6Tobit Laboratories AG TeamDavid's Webbox contains an open redirect vulnerability via the “replyUrl” parameter. An attacker can exploit this vulnerability to craft a URL within the application that, when visited, redirects the user’s browser to an arbitrary third-party site. This can be abused for phishing attacks, where users receive a trusted domain link but are redirected to a phishing website. This issue affects TeamDavid through Rollout 524.4d CVE-2026-54214—

——8Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to HTTP header injection through the “cType” URL parameter, which allows arbitrary modification of the Content-Type header in HTTP responses. Because the parameter does not properly restrict control characters such as URL-encoded newlines (“%0a”) or colons, attackers can inject additional headers including extra Location headers into the server’s response. This results e.g. in an open redirect vulnerability. This issue affects TeamDavid through Rollout 524.4d CVE-2026-12071—

——8The Webbox of TeamDavid by Tobit Laboratories AG constructs redirect URLs using user-supplied input, which is appended to the redirect target in a 302 HTTP response. By using URL-encoded characters such as “%2e” (representing a dot), an attacker can manipulate the portion of the URL following the top-level domain (TLD). If a similar, registerable TLD exists (for example, if “.com” is the application’s domain, and “.company” is available for registration), an attacker can craft a URL to redirect users to a malicious “.company” domain. By using URL-encoded line feeds, it becomes possible to insert arbitrary response headers in the server's HTTP response. This issue affects TeamDavid through Rollout 524.13h CVE-2026-66829—

——16URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the HTML5 scrubber in rrrene html_sanitize_ex allows a remote attacker to force visitors of a page to navigate to a site of the attacker's choosing via a <meta http-equiv="refresh"> element in sanitized HTML. HtmlSanitizeEx.html5/1 keeps attacker-supplied <meta> elements in its output. A meta element acts on the whole document rather than on the fragment it was embedded in, so it can also declare document-wide directives such as Content-Security-Policy. This is not cross-site scripting. Browsers do not navigate a meta refresh to a javascript: URL, so the uppercase JAVASCRIPT: filter bypass yields no script execution and none was demonstrated. This issue affects html_sanitize_ex: from 0.3.1 before 1.5.3.3d CVE-2026-66370—

——9URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the HTML5 scrubber in rrrene html_sanitize_ex allows an unauthenticated remote attacker to retarget a form already on the rendering page and receive whatever the victim submits, including credentials, via the form and formaction attributes on an <input> element in sanitized HTML. HTML's form attribute associates an input with any form on the page by its id even when the input sits outside that form, and formaction on a submit control overrides the owning form's action. Neither attribute receives a scheme check, so an absolute cross-origin URL survives sanitizing. No script executes. The scrubber allows neither form nor button, so the attacker cannot introduce a form of their own and the rendering page must already contain a form carrying an id. This issue affects html_sanitize_ex: from 0.3.1 before 1.5.3.3d
