GHSA-CR4G-F395-H25H
Vulnerability from github – Published: 2026-06-16 23:42 – Updated: 2026-06-16 23:42Summary
PR #37698 added checkDownloadTokenScope to /raw/, /media/, and attachment download web endpoints. The /archive/* endpoint (repo.Download in routers/web/repo/repo.go:372) was not included in the fix. This endpoint accepts OAuth2 tokens via webAuth.AllowOAuth2 (registered at routers/web/web.go:1649-1652) but does not call checkDownloadTokenScope or CheckRepoScopedToken.
A personal access token with any non-repository scope (e.g., read:issue or read:misc) can download full repository archives (zip/tar.gz) of private repositories the token owner has access to.
Impact
Scope escalation: tokens scoped to non-repository categories can access full repository content through the archive download endpoint. Higher impact than endpoints fixed in #37698 because /archive/* serves the entire repository.
Steps to Reproduce
- Create a personal access token with ONLY read:misc scope
- Access: GET /{owner}/{private-repo}/archive/main.tar.gz
- Archive is served (200 OK) instead of being rejected (403 Forbidden)
Compare with fixed endpoints: - GET /{owner}/{private-repo}/raw/branch/main/README.md correctly returns 403
Root Cause
Download function in routers/web/repo/repo.go:372 does not call checkDownloadTokenScope. The outer group middleware reqUnitCodeReader checks repository permission but not token scope.
The API equivalent (/api/v1/repos/{owner}/{repo}/archive/*) IS properly scoped via tokenRequiresScopes(AccessTokenScopeCategoryRepository). The git HTTP endpoints are scoped via CheckRepoScopedToken in httpBase.
Suggested Fix
Add checkDownloadTokenScope(ctx) to Download and InitiateDownload in routers/web/repo/repo.go. The function already exists in routers/web/repo/download.go (same package).
Discovery Method
Variant analysis of PR #37698 — reviewed all web routes with webAuth.AllowOAuth2 middleware.

Vulnerability from github – Published: 2022-07-12 22:15 – Updated: 2022-07-21 14:59Overview
Affected versions have no limit to using unsafe-accessor. Can be ignored if SecurityCheck.AccessLimiter not setup
Details
If UA was loaded as a named module, the internal data of UA will be protected by JVM and others can only access UA via UA's standard api.
Main application can setup SecurityCheck.AccessLimiter for UA to limit accesses to UA.
Untrusted code can access UA without lmitation in affected versions even UA was loaded as a named module.

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.
