Vulnerability from github – Published: 2026-06-16 12:32 – Updated: 2026-06-21 09:30syracom AG Secure Login (2FA) for Atlassian Jira, Confluence, and Bitbucket 3.4.0.x contains an authentication bypass vulnerability. An attacker with valid credentials for a user account can bypass the two-factor authentication flow by sending HTTP requests with a crafted User-Agent header containing specific strings such as AtlassianMobileApp or JIRA. When such a User-Agent is present, the plugin does not enforce the configured 2FA checks for protected web resources. Successful exploitation allows the attacker to access the affected Atlassian application as the compromised user without completing 2FA. If the compromised account has administrative privileges, the attacker can access administrative functionality and may disable the 2FA plugin or make arbitrary administrative changes. The issue is fixed in version 3.5.0.0.

GHSA-XG6X-H9C9-2M83
Vulnerability from github – Published: 2026-04-03 03:29 – Updated: 2026-04-03 03:29Summary
Under certain configurations, sessions may be considered valid before two-factor authentication (2FA) is fully completed. This can allow access to authenticated routes without verifying the second factor.
Description
When two-factor authentication is enabled, the authentication flow correctly identifies users who require additional verification and defers full authentication until the second factor is completed.
However, when session.cookieCache is enabled, the session generated during the initial sign-in step may be cached as valid prior to 2FA verification. Subsequent session lookups may then return this cached session without re-evaluating the 2FA requirement.
This results in a situation where session validity can be established before all authentication constraints are satisfied.
Impact
An attacker (or user) with valid primary credentials may gain access to protected application routes without completing the required second authentication factor.
Any application using better-auth with both two-factor authentication and session cookie caching enabled may be affected.
Mitigation
- Upgrade to a version of
better-auththat includes the fix for this issue. - Ensure that session caching does not treat sessions as fully authenticated until all required authentication steps, including 2FA, are completed.
- As a temporary workaround, disable
session.cookieCachewhen using two-factor authentication.

This is due to insufficient verification on the 'phone' parameter of the 'firebase_sms_login' and 'firebase_sms_login_v2' functions. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email address or phone number. Additionally, if a new email address is supplied, a new user account is created with the default role, even if registration is disabled.

Mitigation
Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
CAPEC-127: Directory Indexing
An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.
CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
