Moderate
Forceu published GHSA-c36c-7pc2-f2ph Mar 5, 2026

Package

Gokapi

Affected versions

<v2.2.3

Patched versions

2.2.3

Description

Description

The upload status SSE implementation on /uploadStatus publishes global upload state to any authenticated listener and includes file_id values that are not scoped to the requesting user. S

Impact

Any authenticated user can observe other users' file identifiers and retrieve unauthorized content, causing cross-tenant data exposure and loss of confidentiality for uploaded documents.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
