CVE-2026-35104

HCL AION is affected by multiple security vulnerabilities.

HCL AION is affected by an open redirect vulnerability on the user registration page (Signup component). The redirect performed after registration used the value of the 'redirect' query parameter without validation, so a crafted registration link could send a user to an untrusted external site. This may be used in phishing attacks, potentially resulting in unintended behavior or security impact under certain conditions.

Open redirect vulnerability - UCMDB/Operations Bridge Manager

An Open Redirect vulnerability has been identified in OpenText™ Universal Discovery and CMDB. The vulnerability can be exploited only if an attacker sends a specially crafted URL containing a link to a malicious resource and a user subsequently follows that link. Affected systems: This issue affects only the classic deployment options for UCMDB UI (ucmdb-browser) component within Universal Discovery and CMDB and Operations Bridge Manager. Containerized deployment options are not affected.

NationalSecurityAgency/emissary: Incomplete fix for CVE-2026-35571: SSRF

Emissary is a P2P based data-driven workflow engine. Prior to 8.51.0, the VALID_LINK validation in src/main/java/emissary/server/mvc/NavAction.java accepts protocol-relative URLs when processing configured navigation links. Browser URL normalization can interpret these accepted strings as external origins. The authoritative advisory attributes open redirect, server-side request forgery, and cloud metadata access to this bypass, but it identifies neither the server-side dereference path nor how navigation-link processing reaches that path. This issue is fixed in version 8.51.0.

Freeipa: idm: idm/freeipa web ui - client-side open redirect in reset_password.html

reset_password.html parses query string parameters and uses the 'url' parameter as a redirection target (window.location = url) after password reset, optionally delayed by a 'delay' parameter. No validation or allowlisting is performed on url, enabling an attacker to redirect users to an arbitrary external site after completion of the password-reset workflow.

go-chi chi 5.2.2 through 5.5.0 Open Redirect via RedirectSlashes Middleware

go-chi chi 5.2.2 through 5.5.0 contains an open redirect vulnerability in the RedirectSlashes middleware that allows attackers to redirect victims to external hosts by embedding tab characters in request paths. Attackers can craft links with a URL-encoded tab, which browsers strip from the 301 Location header and resolve as a protocol-relative URL, bypassing the fix for CVE-2025-69725.

Spacewalk: spacewalk: open redirect vulnerability enables phishing attacks via url parameter

A flaw was found in Spacewalk, as used in Red Hat Network Satellite. This open redirect vulnerability allows remote attackers to redirect users to arbitrary web sites by manipulating a URL in the url_bounce parameter. This can enable attackers to conduct phishing attacks, potentially leading to unauthorized information disclosure or credential theft.

Symfony: HtmlSanitizer MetaRefreshAttributeSanitizer Matches Only a Narrow Subset of the Browser Refresh Grammar (Incomplete Fix for CVE-2026-48761)

The Symfony HtmlSanitizer component MetaRefreshAttributeSanitizer, introduced to fix CVE-2026-48761, sanitizes the refresh URL of content attributes of meta tags using a regular expression that is too narrow, allowing sanitization to be bypassed, and resulting in potential URL redirection to untrusted sites in Symfony versions 6.1.x prior to 6.4.50, 7.x prior to 7.4.23, and 8.x prior to 8.1.11. The shared declarative refresh steps in the WHATWG HTML Standard require a broader approach: the separator after the time may be ASCII whitespace alone, with no ; or ,, and the url= keyword is optional. Directives the browser honours, but the regular expression misses are returned unchanged, so the attacker URL skips UrlSanitizer entirely and both allowLinkSchemes and allowLinkHosts are defeated for the refresh navigation. This is reachable under any configuration that allows meta with http-equiv and content, including the documented allowStaticElements() preset.

CVE-2026-118180

Matrix homeserver could redirect the chat session to a local file or network share

When logging in to a Matrix account, Thunderbird used the homeserver address provided in the server's login response without validating it. A malicious or compromised homeserver could provide a file: URL, causing Thunderbird to send all further Matrix requests of that session to local files or, on Windows, to an attacker-controlled network share, which could leak the user's NTLM credentials. The NTLM credential leak only affects Thunderbird on Windows. Other operating systems are unaffected. This vulnerability was fixed in Thunderbird 159 and Thunderbird 153.6.

Calendar discovery accepted local file and remote network share locations

When looking for calendars in a directory on a server, during account setup or when adding a new network calendar, Thunderbird accepted calendar locations pointing to other servers, local files or network shares. A malicious server, or a network attacker when the lookup used plain HTTP, could make Thunderbird subscribe to such a location. On Windows this could leak the user's NTLM credentials to an attacker-controlled host on every calendar refresh, and changes to the calendar could be written to the attacker's share or overwrite a local file. This vulnerability was fixed in Thunderbird 159 and Thunderbird 153.6.

Displaying a message could load an attacker-chosen URL through an OpenPGP key attachment

When a message containing an OpenPGP key attachment was displayed, Thunderbird automatically loaded the attachment's content to offer importing the key. A sender could mark the attachment as an external attachment pointing to an arbitrary URL, which Thunderbird then loaded without any user interaction, bypassing remote content blocking. On Windows, a URL pointing to an attacker-controlled network share could leak the user's NTLM credentials. The NTLM credential leak only affects Thunderbird on Windows. On other operating systems, the issue allowed a remote request that bypassed remote content blocking. This vulnerability was fixed in Thunderbird 159 and Thunderbird 153.6.

Angular: Open Redirect via Protocol-Relative URLs in Server-Side Rendering (SSR)

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.33, 21.2.25, and 22.2.1, ServerPlatformLocation in Angular server-side rendering checks for protocol-relative URLs before WHATWG URL normalization. A request path containing a popping dot segment followed by multiple slashes can bypass the raw resolveUrl check and normalize to a pathname beginning with two slashes. When Angular SSR detects a mismatch with the router's final location, it can place that pathname in an HTTP Location header, causing a browser to navigate to an attacker-controlled origin. Affected applications use @angular/platform-server and @angular/ssr and either expose compatible parameter or child route shapes or pass user-controlled navigation targets through infrastructure that preserves the relevant dot segments or semicolons. Pure client-side SPAs are not affected. This issue is fixed in versions 20.3.33, 21.2.25, and 22.2.1.
