Title
Coder before 2.34.2 User Enumeration via Login Placeholder Hash
Summary
Coder before 2.29.17, 2.30.0 before 2.32.7, 2.33.0 before 2.33.8, and 2.34.0 before 2.34.2 contains a user enumeration vulnerability because userpassword.Compare() substitutes a placeholder hash derived from the string "hunter2" when a stored password hash is empty. Unauthenticated attackers can submit logins with the password "hunter2" and distinguish HTTP 403 from 401 responses to enumerate valid accounts and reveal the authentication provider of SSO-only users.

Title
Openssh: openssh: shared lz77 compression dictionary leaks plaintext across channels
Summary
A flaw was found in OpenSSH. When compression is negotiated, channels on the same connection share one LZ77 dictionary. A peer who can write on one channel can recover plaintext from another channel by chosen-plaintext lengths.

Title
SurrealDB before 3.3.0 Field Permission Bypass via LIVE SELECT WHERE Clause
Summary
SurrealDB before 3.3.0 contains an authorization bypass vulnerability that allows record users to infer field values hidden by field-level SELECT permissions using LIVE SELECT WHERE predicates over $before or $after. Attackers can craft repeated predicates and observe whether notifications are delivered on CREATE, UPDATE, or DELETE to confirm or narrow restricted field values.

Title
Backstage: Improper input validation in scaffolder task list ordering
Summary
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper input validation in scaffolder task list ordering. An authenticated Backstage user with permission to create and read relevant scaffolder tasks may be able to infer confidential task data under specific conditions. Successful exploitation requires retained task secrets, visibility of a target task, knowledge of the secret structure, and repeated requests. This issue is fixed in version 4.1.0.

Title
Ghost: Invite Token Disclosure in Ghost Admin API
Summary
Ghost is a Node.js content management system. From 4.39.0 until 6.64.0, staff users with permission to view staff invites were able to discover the secret token of pending invites, including invites for roles with higher privileges than their own. This could allow a staff user to escalate their privileges by accepting a pending invite. This issue is fixed in version 6.64.0.

Title
Ghost: Password Hash Ordering Disclosure in Ghost Admin API
Summary
Ghost is a Node.js content management system. From 0.7.2 until 6.64.0, any staff-level user was able to determine the relative ordering of other staff users' hashed passwords. This does not directly disclose password hashes, and does not provide a practical path to recovering a password. This issue is fixed in version 6.64.0.

Title
Ghost 0.7.2 before 6.64.0 Password Hash Ordering Disclosure via Admin API
Summary
Ghost from 0.7.2 before 6.64.0 contains an information disclosure vulnerability in the Admin API that allows staff-level users to determine the relative ordering of other staff users' password hashes. Authenticated staff users can query the Admin API to infer hash ordering, though this does not directly reveal hashes or enable practical password recovery.

Title
Ghost 5.42.2 before 6.58.0 Password Hash Disclosure
Summary
Ghost 5.42.2 before 6.58.0 contains an information disclosure vulnerability in the Admin API bulk post and page edit and delete endpoints, which accept filters on restricted fields such as authors.password, because of an incomplete fix for CVE-2026-70590.

Mitigation MIT-46
Architecture and Design

Strategy: Separation of Privilege

  • Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation MIT-39
Implementation
  • Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success.
  • If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files.
  • Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
CAPEC-189: Black Box Reverse Engineering

An adversary discovers the structure, function, and composition of a type of computer software through black box analysis techniques. 'Black Box' methods involve interacting with the software indirectly, in the absence of direct access to the executable object. Such analysis typically involves interacting with the software at the boundaries of where the software interfaces with a larger execution environment, such as input-output vectors, libraries, or APIs. Black Box Reverse Engineering also refers to gathering physical side effects of a hardware device, such as electromagnetic radiation or sounds.
