Gokapi vulnerable to Privilege Escalation in File Replace

Moderate severity GitHub Reviewed Published Mar 13, 2026 in Forceu/Gokapi • Updated Mar 24, 2026

Package

gomod github.com/forceu/gokapi (Go)

Affected versions

<= 2.2.3

Patched versions

2.2.4

Description

Summary

An insufficient authorization check in the file replace API allows a user with only list visibility permission (UserPermListOtherUploads) to delete another user's file by abusing the deleteNewFile flag, bypassing the requirement for UserPermDeleteOtherUploads.

Impact

Any authenticated user with PERM_REPLACE (replace own files) and PERM_LIST (view other users' uploads) can delete any other user's file without needing PERM_DELETE.

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.
