CVE-2026-25714: Gitea Token Leakage via Organization API – Patch Guidance

Technical summary

CVE-2026-25714 stems from insufficient token filtering logic in Gitea's user organization API endpoints. The vulnerability affects Gitea versions up to and including 1.26.1. The root cause is a bypass of public-only token restrictions that were intended to be enforced as part of the prior CVE-2025-68941 remediation. An authenticated user with API access can craft requests to organization endpoints that do not properly validate token visibility constraints, resulting in disclosure of private or restricted tokens that should have been filtered. This is classified as an authorization bypass (CWE-862) with a CVSS v3.1 score of 4.3 (Medium severity), reflecting limited impact but exploitable by low-privileged authenticated users.

Business impact

Token exposure in a self-hosted Git platform poses operational risk proportional to how widely Gitea is used within an organization. Compromised tokens can grant attackers persistent API access, enable lateral movement across repositories, trigger unauthorized CI/CD pipelines, or facilitate supply-chain attacks if the Git instance hosts critical source code. The impact is primarily to confidentiality; integrity and availability are not directly affected. For organizations relying on Gitea as a central development platform, this represents a credential hygiene concern that could amplify the blast radius of other security incidents.

Affected systems

Gitea versions up to and including 1.26.1 are affected. The vulnerability is specific to the user organization API; other Gitea APIs and functionality are not described as impacted. Self-hosted Gitea instances in any environment—on-premises, cloud, or hybrid—are in scope. The vulnerability requires an authenticated attacker with valid API credentials, so it does not affect unauthenticated access.

Exploitability

Exploitability is straightforward for users with valid Gitea accounts and API token access. No complex exploitation techniques, network positioning, or user interaction is required. An attacker need only issue crafted API calls to organization endpoints to enumerate and retrieve tokens they are not authorized to see. The low barrier to exploitation and the presence of a prior, incomplete fix suggest this issue may have been discovered through security testing or fuzzing of the remediation for CVE-2025-68941. However, the vulnerability is not currently listed in CISA's Known Exploited Vulnerabilities (KEV) catalog.

Remediation

Organizations should upgrade Gitea to a version that fully addresses token filtering in the user organization API. Verify the patch version against Gitea's official security advisories and release notes. In the interim, restrict API access using network controls or authentication policies, and audit token usage and permissions to identify any anomalies. Review logs for organization API calls that may indicate exploitation. Additionally, consider rotating high-value tokens or those used in critical workflows.

Patch guidance

Check Gitea's official security advisories and GitHub release notes for a patched version that resolves token filtering across all organization API endpoints. Apply the patch during a scheduled maintenance window; upgrades typically require a brief service restart. Before patching production, validate the fix in a non-production environment. Verify that token filtering is now enforced consistently and that previously exposed tokens are no longer accessible via the organization API.

Detection guidance

Monitor Gitea API logs for unusual patterns in organization endpoint requests, particularly from accounts with limited permissions accessing organization-level resources. Alert on repeated 200 (success) responses to organization API calls that retrieve token data. Review access logs for sequences of calls that suggest token enumeration. Conduct periodic audits of token grants and verify that only intended principals can view each token. If you maintain detailed API audit logs, search for requests to organization endpoints with filter parameters or pagination that might indicate token harvesting.

Why prioritize this

This vulnerability merits prompt but not emergency attention. The Medium CVSS score (4.3) reflects that exploitation requires authentication and yields limited confidentiality impact. However, it is a direct bypass of a prior security fix, indicating either incomplete testing or a subtle implementation flaw. Organizations with high-value source code or sensitive CI/CD pipelines should prioritize patching sooner; those using Gitea for less critical workloads may schedule patching in the next regular maintenance cycle. The vulnerability is not yet in active exploitation (not on KEV), which provides a window for orderly remediation.

Risk score, explained

The CVSS v3.1 score of 4.3 (Medium) reflects: Network-accessible API (AV:N) requiring only Low privilege and no user interaction (PR:L, UI:N); a single scope (S:U); and impact limited to Confidentiality (C:L). Integrity and Availability are not affected. The score appropriately penalizes the authorization bypass nature of the flaw but recognizes that exploitation requires valid authentication and yields token disclosure rather than data destruction or service disruption.
