REST API exposes organization membership of private organizations to public
AI Analysis
Technical Summary
A vulnerability identified as CVE-2026-58417 affects Gitea's REST API in versions before 1.27.0. The flaw allows unauthorized users possessing an API token to verify whether specific users are members of private organizations by querying the endpoint /orgs/{org}/public_members/{username}.

Potential Impact
The vulnerability can lead to unauthorized disclosure of private organizational membership information. This exposure may compromise privacy and confidentiality of organization members, potentially aiding attackers in reconnaissance or social engineering. There is no indication of privilege escalation or direct system compromise. No known exploits are reported in the wild.
Mitigation Recommendations
A patch is available for this vulnerability in Gitea version 1.27.0 and later. Users should upgrade to version 1.27.0 or newer to remediate this issue. Since this is not a cloud service, remediation requires applying the update to affected installations.
