GHSA-5353-F8FQ-65VC
Vulnerability from github – Published: 2026-03-23 19:56 – Updated: 2026-03-30 14:06Summary
A logic flaw in the universal secure verification flow allows an authenticated user with a registered passkey to satisfy secure verification without completing a WebAuthn assertion.
Affected versions
= v0.10.0
Description
The POST /api/verify endpoint supports multiple secure verification methods, including passkeys. When the request body contains {"method":"passkey"}, the server only checks whether the authenticated account has a passkey record on file and then marks the secure verification session as complete. It does not verify that the requester successfully completed a WebAuthn assertion.
As a result, an authenticated user who already has a valid session and a registered passkey can satisfy the secure verification requirement without performing the intended passkey challenge/response flow.
Impact
In the upstream project, this issue affects actions protected by SecureVerificationRequired(). At the time of publication, the confirmed upstream impact is the root-only POST /api/channel/:id/key endpoint, which returns stored channel secrets.
Successful exploitation requires: - an already authenticated session for the target account, and - a registered passkey on that account.
No full login bypass or cross-account privilege escalation has been confirmed in the upstream codebase. However, the issue defeats the intended step-up verification control for affected privileged actions.
Workarounds
Until a patched release is applied: - do not rely on passkey as the step-up method for privileged secure-verification actions; - require TOTP/2FA for those actions where operationally possible; or - temporarily restrict access to affected secure-verification-protected endpoints.

Mitigation
Strategy: Libraries or Frameworks
Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CAPEC-114: Authentication Abuse
An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.
CAPEC-115: Authentication Bypass
An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.
CAPEC-151: Identity Spoofing
Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.
CAPEC-194: Fake the Source of Data
An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.
CAPEC-22: Exploiting Trust in Client
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data
This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.
CAPEC-593: Session Hijacking
This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.
CAPEC-633: Token Impersonation
An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.
CAPEC-650: Upload a Web Shell to a Web Server
By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.
CAPEC-94: Adversary in the Middle (AiTM)
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
