The internet is broken right now.

CallBackery versions before 0.62.0 for Perl accept session cookies of any age sent in the X-Session-Cookie header. cookieConf() rejects a cookie older than 300 seconds only when it arrives in the xsc query parameter. The same cookie sent in the X-Session-Cookie header is accepted however old it is. A session cookie that leaks through a log, a Referer header or browser history authenticates as its user indefinitely.

Jenkins 2.587 and earlier, LTS 2.580.1 and earlier improperly identifies file paths attempting path traversal in the file browser for workspaces and $JENKINS_HOME/userContent/, allowing attackers with Overall/Read permission to obtain the names, sizes, and last modification times of files in the $JENKINS_HOME, and attackers with Item/Workspace permission to obtain the names of jobs that have a workspace on the same agent.

Some externally supplied values stored by the device may be rendered in the web interface without sufficient output encoding. An attacker who can influence one of these values could cause script execution in the browser of a user who views an affected page. Exploitation requires an attacker to influence a stored value and a user to view a page that renders it.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a CSS scoping bypass in HTML messages. rcube_utils::mod_css_styles() did not treat an at-rule prologue such as @layer a; as a selector boundary, and did not handle selectors beginning with ::, so selectors following an at-rule were left unscoped and applied to the whole Roundcube interface instead of being confined to the message body. This allows an HTML message to restyle application chrome for UI redressing and spoofing. Upstream fixed this in the commit “Fix CSS scoping bypass in HTML messages using at-rules”.

GFI KerioConnect (Kerio Connect) before 10.0.9 Patch 2 contains a cross-site scripting vulnerability in the Webmail component that allows a remote attacker to spoof link targets or inject HTML into a message as rendered in a victim's authenticated Webmail session by sending a crafted email whose text is already inside a link. Attackers can exploit the link auto-formatter's re-processing of already-linked text, using quote characters to break out of the href attribute and inject attacker-controlled markup to execute script in the victim's session.

Postiz signs its session, invitation and password reset tokens with one shared secret and without any marker of what a token is for. A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back. A user could therefore obtain a validly signed token containing any claims they choose, which the application accepts as a session, as an organization invitation with a chosen role, as a password reset or as an enterprise provisioning token. A second, narrower route that creates team invitations signs extra fields from the request body in the same way.

Nuxt UI is an intuitive Vue UI library powered by Reka UI and Tailwind CSS. Prior to 4.8.1, the server-rendered form element produced by UForm in src/runtime/components/Form.vue omits the method and action attributes and relies solely on the hydrated @submit.prevent handler to stop native submission. UAuthForm composes UForm and can render named credential fields, including an input with type password, inside the same markup. If a user submits before Vue hydration completes, or when the client bundle is blocked or unavailable, the browser performs its default GET submission and serializes the named fields into the current URL query string. The credentials can then appear in the address bar, browser history, reverse-proxy, CDN, or WAF request logs, and Referer headers sent with same-origin subresource requests. This issue is fixed in version 4.8.1.

An attacker positioned on the network during account setup could cause such a URL to be configured. This vulnerability was fixed in Thunderbird 160 and Thunderbird 153.7.

Ladybird is a truly independent web browser. Prior to 209579c96473c75bd5eba9701fcadb841a045964, FinalizationRegistry::cleanup() in Libraries/LibJS/Runtime/FinalizationRegistry.cpp removed a dead record from m_records, retained an iterator to the next FinalizationRecord, and then invoked attacker-controlled JavaScript through the cleanup callback. If that callback called unregister() for the next record, remove_by_token() freed the node referenced by the retained iterator, and the next cleanup iteration read its target and held_value fields after free. This reliably crashes instrumented WebContent builds and creates a memory-corruption primitive in production builds. This vulnerability is fixed by commit 209579c96473c75bd5eba9701fcadb841a045964.
