Relationships and members
Modes of introduction
OMISSION: This weakness is caused by missing a security tactic during the architecture and design phase.
Authorization weaknesses may arise when a single-user application is ported to a multi-user environment.
A developer may introduce authorization weaknesses because of a lack of understanding about the underlying technologies. For example, a developer may assume that attackers cannot modify certain inputs such as headers or cookies.
Detection methods
Automated Static Analysis
Automated static analysis is useful for detecting commonly-used idioms for authorization. A tool may be able to analyze related configuration files, such as .htaccess in Apache web servers, or detect the usage of commonly-used authorization libraries.
Generally, automated static analysis tools have difficulty detecting custom authorization schemes. In addition, the software's design may include some functionality that is accessible to any user and does not require an authorization check; an automated technique that detects the absence of authorization may report false positives.
Effectiveness: Limited
Automated Dynamic Analysis
Automated dynamic analysis may find many or all possible interfaces that do not require authorization, but manual analysis is required to determine if the lack of authorization violates business logic.
Manual Analysis
This weakness can be detected using tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session.
Specifically, manual static analysis is useful for evaluating the correctness of custom authorization mechanisms.
Effectiveness: Moderate
These may be more effective than strictly automated techniques. This is especially the case with weaknesses that are related to design and business rules. However, manual efforts might not achieve desired code coverage within limited time constraints.
Manual Static Analysis - Binary or Bytecode
According to SOAR [REF-1479], the following detection techniques may be useful:
Cost effective for partial coverage:
Binary / Bytecode disassembler - then use manual analysis for vulnerabilities & anomalies
Effectiveness: SOAR Partial
Dynamic Analysis with Automated Results Interpretation
According to SOAR [REF-1479], the following detection techniques may be useful:
Cost effective for partial coverage:
Web Application Scanner
Web Services Scanner
Database Scanners
Effectiveness: SOAR Partial
Dynamic Analysis with Manual Results Interpretation
According to SOAR [REF-1479], the following detection techniques may be useful:
Cost effective for partial coverage:
Host Application Interface Scanner
Fuzz Tester
Framework-based Fuzzer
Effectiveness: SOAR Partial
Manual Static Analysis - Source Code
According to SOAR [REF-1479], the following detection techniques may be useful:
Cost effective for partial coverage:
Focused Manual Spotcheck - Focused manual analysis of source
Manual Source Code Review (not inspections)
Effectiveness: SOAR Partial
Automated Static Analysis - Source Code
According to SOAR [REF-1479], the following detection techniques may be useful:
Cost effective for partial coverage:
Source code Weakness Analyzer
Context-configured Source Code Weakness Analyzer
Effectiveness: SOAR Partial
Architecture or Design Review
According to SOAR [REF-1479], the following detection techniques may be useful:
Highly cost effective:
Inspection (IEEE 1028 standard) (can apply to requirements, design, source code, etc.)
Formal Methods / Correct-By-Construction
Effectiveness: High
Notes
Terminology
Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user's privileges and any permissions or other access-control specifications that apply to the resource.

GHSA-67X2-MQ63-V9VM
Vulnerability from github – Published: 2026-09-03 22:52 – Updated: 2026-09-03 22:52CVE: This vulnerability corresponds to CVE-2026-72805.
Summary
Three block endpoints return document content snippets and metadata without any publish-access check, while their sibling getBlockInfo which returns comparable data does enforce one. All three are CheckAuth-only, so they are reachable by the publish RoleReader token and by the anonymous account when Publish.Auth.Enable is false. An anonymous reader supplying a block ID receives content and metadata belonging to publish-forbidden and password-protected documents.
Details
getBlockInfo (kernel/api/block.go) gates on the publish boundary:
if !checkBlockPublishAccess(c, id, ret) {
return
}
The following siblings in the same file perform no equivalent check:
| Endpoint | Returns | Publish check |
|---|---|---|
getBlockInfo |
root/title/path metadata | checkBlockPublishAccess: present |
getBlockBreadcrumb |
BlockPath.Name : root document title plus every ancestor block's content snippet |
none |
getRefText |
the block's reference/anchor text (document content) | none |
getBlockTreeInfos |
root/title/path metadata for arbitrary block IDs | none |
getBlockBreadcrumb returns the full ancestor chain including each ancestor block's content snippet, and getRefText returns block anchor text both are document content, not just metadata. getBlockTreeInfos returns root/title/path for any caller-supplied ID set via model.GetBlockTreeInfosInBox(...) with no gate.
getBlockBreadcrumb and getRefText additionally accept a client-supplied notebook argument that routes to the *InBox variants, so the same unguarded path applies to encrypted-notebook reads while the notebook is unlocked.
The correct primitive already exists in the codebase and is used by getBlockInfo; these three handlers simply do not call it.
Proof of Concept
Precondition: publish mode enabled (default port 6808); anonymous when Publish.Auth.Enable is false, otherwise any publish reader account. A document D is marked publish-forbidden (or password-protected) and contains a block BLOCK_ID under a heading with distinctive content.
Control: the gated sibling correctly refuses:
POST http://127.0.0.1:6808/api/block/getBlockInfo
{"id":"BLOCK_ID"}
Blocked by checkBlockPublishAccess.
Disclosure: the ungated siblings return the data anyway:
POST http://127.0.0.1:6808/api/block/getBlockBreadcrumb
{"id":"BLOCK_ID"}
→ ancestor chain including the forbidden document's title and ancestor block content snippets
POST http://127.0.0.1:6808/api/block/getRefText
{"id":"BLOCK_ID"}
→ the block's reference/anchor text (content of the forbidden document)
POST http://127.0.0.1:6808/api/block/getBlockTreeInfos
{"ids":["BLOCK_ID"]}
→ root ID, title, and path for the forbidden document
Verified by code inspection at origin/master (eef10568): getBlockInfo contains the checkBlockPublishAccess call; getBlockBreadcrumb, getRefText, and getBlockTreeInfos contain no publish-access, publish-ignore, or readonly-role check in their bodies.
Impact
An anonymous reader (publish mode with auth disabled) or any publish RoleReader can read, for documents explicitly excluded from publishing or protected by a publish password:
- the document title and full ancestor chain, including ancestor block content snippets (getBlockBreadcrumb);
- block reference/anchor text, i.e. document content (getRefText);
- root ID, title, and path metadata for arbitrary block IDs (getBlockTreeInfos).
Because getBlockBreadcrumb and getRefText accept a notebook argument routing to the *InBox variants, the same disclosure applies to encrypted notebooks while unlocked. Confidentiality-only; the precondition is a block ID, obtainable from other reader-reachable endpoints.
Suggested fix
Call checkBlockPublishAccess (as getBlockInfo does) in getBlockBreadcrumb, getRefText, and getBlockTreeInfos before returning data for getBlockTreeInfos, apply it per ID and drop unauthorized entries. Confirm the *InBox variants (GetBlockRefTextInBox, BuildBlockBreadcrumbInBox) enforce the same boundary so the notebook-argument path is covered.

"details": "**CVE:** This vulnerability corresponds to [CVE-2026-72805](https://nvd.nist.gov/vuln/detail/CVE-2026-72805).\n\n### Summary\n\nThree block endpoints return document content snippets and metadata without any publish-access check, while their sibling `getBlockInfo` which returns comparable data does enforce one. All three are `CheckAuth`-only, so they are reachable by the publish `RoleReader` token and by the anonymous account when `Publish.Auth.Enable` is `false`. An anonymous reader supplying a block ID receives content and metadata belonging to publish-forbidden and password-protected documents.\n\n### Details\n\n`getBlockInfo` (`kernel/api/block.go`) gates on the publish boundary:\n```go\nif !checkBlockPublishAccess(c, id, ret) {\n return\n}\n```\n\nThe following siblings in the same file perform no equivalent check:\n\n| Endpoint | Returns | Publish check |\n|---|---|---|\n| `getBlockInfo` | root/title/path metadata | `checkBlockPublishAccess`: present |\n| `getBlockBreadcrumb` | `BlockPath.Name` : root document title plus every ancestor block\u0027s content snippet | none |\n| `getRefText` | the block\u0027s reference/anchor text (document content) | none |\n| `getBlockTreeInfos` | root/title/path metadata for arbitrary block IDs | none |\n\n`getBlockBreadcrumb` returns the full ancestor chain including each ancestor block\u0027s content snippet, and `getRefText` returns block anchor text both are document content, not just metadata. `getBlockTreeInfos` returns root/title/path for any caller-supplied ID set via `model.GetBlockTreeInfosInBox(...)` with no gate.\n\n`getBlockBreadcrumb` and `getRefText` additionally accept a client-supplied notebook argument that routes to the `*InBox` variants, so the same unguarded path applies to encrypted-notebook reads while the notebook is unlocked.\n\nThe correct primitive already exists in the codebase and is used by `getBlockInfo`; these three handlers simply do not call it.\n\n### Proof of Concept\n\nPrecondition: publish mode enabled (default port 6808); anonymous when `Publish.Auth.Enable` is `false`, otherwise any publish reader account.

Mitigation
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
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.
