Null Pointer Dereference in AddTime API Causes Authenticated Denial of Service
AI Analysis
Technical Summary
The vulnerability in Gitea's AddTime API handler occurs when a repository administrator inputs a non-existent user name. Although the API returns an error, it proceeds with execution, leading to a nil pointer dereference and a runtime panic. This causes the server to crash or the request to fail, resulting in an authenticated denial of service condition. The issue affects versions prior to 1.27.0 and has been assigned CVE-2026-55984. The CVSS 3.1 base score is 2.7, reflecting low severity with no confidentiality or integrity impact. A patch is available to fix this issue.
Potential Impact
An authenticated user with repository administrator privileges can cause the Gitea server to crash or requests to fail by specifying a non-existent user name in the AddTime API. This results in a denial of service condition affecting availability only. There is no impact on confidentiality or integrity.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade Gitea to version 1.27.0 or later to remediate the issue. No additional mitigation steps are required beyond applying the official fix.
