Title
Apache Wicket: A cross-origin listener invocation stopped by a login wall is replayed after the user signs in
Summary
Incorrect order of security checks in Apache Wicket.
org.apache.wicket.protocol.http.ResourceIsolationRequestCycleListener obtains the page a request targets before it consults its resource isolation policies, because those policies are passed that page. Obtaining the page instantiates it, and instantiating a page runs the configured org.apache.wicket.authorization.IAuthorizationStrategy. An application that refuses an unauthenticated visitor by throwing org.apache.wicket.RestartResponseAtInterceptPageException therefore throws it from inside the isolation listener, before any policy has run. That exception replaces the request handler, so the policies are never consulted and a request that came from another origin is not refused.
The exception's constructor stores the URL of the request it interrupted, so that Component#continueToOriginalDestination() can resume it once the visitor has signed in. The stored URL is the one the policies would have refused. On sign in Wicket redirects to it, and that redirect is same-origin, so the policies allow it and the listener runs in the newly authenticated session. The whole URL is stored, its query string included, so an ordinary org.apache.wicket.markup.html.form.Form is resumed with the field values the original request carried in its query string and Form#onSubmit() runs with values another origin chose. A form POST is not needed for this; a plain top-level navigation carries them.
An application is affected where it registers ResourceIsolationRequestCycleListener, which is opt-in and is not registered by default, and where it refuses unauthorized access with RestartResponseAtInterceptPageException followed by continueToOriginalDestination(). No application override is involved on that path: IAuthorizationStrategy#isInstantiationAuthorized() documents throwing that exception, org.apache.wicket.authroles.authentication.AuthenticatedWebApplication throws it and org.apache.wicket.authroles.authentication.panel.UsernamePasswordPanel continues to the original destination, and org.apache.wicket.authorization.strategies.page.SimplePageAuthorizationStrategy in wicket-core installs the same pattern. A visitor who is already signed in is not affected, because no interception occurs. Request-body parameters stored alongside the intercepted URL are not applied to the resumed form: the resumption is a redirect, so the resumed request is a GET, and form components read their values from the query string on a GET.
As a workaround, refuse unauthorized access with org.apache.wicket.RestartResponseException instead, which does not store the original destination; visitors are then not returned to the page they asked for after signing in.
This issue affects Apache Wicket: from 9.1.0 through 9.24.0, from 10.0.0 through 10.11.0.
Releases before 9.1.0, which is every 8.x release and 9.0.0, are not affected, because the resource isolation this issue concerns was introduced in 9.1.0. They are not protected either. Their only cross-origin defence is org.apache.wicket.protocol.http.CsrfPreventionRequestCycleListener, which works out where a request came from by reading its Origin header and falling back to its Referer header. Neither header need arrive: a browser does not send Origin on the plain GET a link uses, and the document on the other origin decides through its own referrer policy whether a Referer reaches the application at all. That mechanism therefore never made the guarantee the Fetch Metadata based policy makes, and on those releases a listener invocation from another origin is not reliably refused in the first place. Anyone on a release before 9.1.0 who wants this protection should upgrade to 9.x or 10.x and register ResourceIsolationRequestCycleListener.
Users are recommended to upgrade to version 9.25.0 or 10.12.0, which fix the issue.

Title
Gitea second-factor bypass through OpenID identity linking
Summary
Gitea's OpenID connect handler accepts a user's password without enforcing enrolled TOTP or WebAuthn verification before completing sign-in and linking an OpenID identifier. When OpenID sign-in is enabled, an attacker who knows the victim's password can obtain a session and link an attacker-controlled identifier. The attacker can then sign in through that identifier without the victim's password or second factor, and a password change does not remove the link.

Title
Security Advisory 0160
Summary
On affected platforms running Arista EOS with IS-IS configured on a broadcast interface, an unauthenticated attacker can send a crafted IS-IS Hello Protocol Data Unit (PDU) that causes the device to tear down an established IS-IS adjacency. This may result in traffic disruption and loss of IP reachability for prefixes advertised through that adjacency.

Title
Russh: Channel-scoped server callbacks can be reached without an open channel
Summary
Russh is a Rust SSH client & server library. Prior to 0.62.5, russh dispatches channel-scoped Handler callbacks for recipient channel IDs that were never opened or confirmed in russh/src/server/encrypted.rs, server_read_authenticated, and the exec_request callback. Version 0.62.5 fixes the issue.

Title
cJSON JSON Patch Non-Atomic Application Destroys Data Before Validation
Summary
cJSON through 1.7.19 applies RFC 6902 JSON Patch operations non-atomically in apply_patch() in cJSON_Utils.c. For a replace operation that is missing its value member, or a move operation whose destination path cannot be resolved, the existing target member is detached and deleted before the operation is fully validated, so the target document is mutated while cJSONUtils_ApplyPatches() or cJSONUtils_ApplyPatchesCaseSensitive() returns a failure status. An attacker who can supply the patch document can destroy addressable members of the target document even though the API reports that the patch failed, defeating the all-or-nothing behavior callers rely on to reject bad patches.

Title
Apache Traffic Server: HPACK encoder desynchronizes from the decoder after a failed header encode
Summary
Apache Traffic Server updates the HTTP/2 HPACK dynamic table before confirming the header block encoded successfully, so an encode failure leaves the encoder out of sync with the peer decoder and corrupts subsequent header blocks on the connection.
This issue affects Apache Traffic Server: from 8.0.0 through 8.1.11, from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3.
Users are recommended to upgrade to version 9.2.15 or 10.1.4, which fix the issue.

Title
Indian Scout Bobber 2025 Infotainment Digital Round skips PIN entry when WCM is silent at boot
Summary
Incorrect behavior order in the Infotainment / Digital Round display of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker to bypass the PIN entry screen. The Infotainment uses presence of Wireless Control Module (WCM) traffic during its boot window as a proxy for whether an immobilizer is fitted; if no WCM messages are observed, it skips the PIN entry screen and shows the normal user interface. An attacker who silences the WCM during the boot window — for example via a separately tracked CAN bus-off technique — can present a fully unlocked Infotainment despite the PIN never being entered. Specific timing and protocol details have been withheld pending vendor remediation.

CAPEC-463: Padding Oracle Crypto Attack
An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.
