Summary
Privilege Escalation via Access Token Scope Escalation in API A flaw was found in Gitea. This vulnerability allows an attacker to escalate their privileges by manipulating the scope of an access token within the API.
This means an attacker could gain unauthorized access to sensitive functions or data, potentially leading to full control over affected resources. This is due to a flaw in how Gitea's API processes basic authentication with tokens, allowing the creation of new tokens with elevated scopes beyond the original token's permissions.
Red Hat OpenShift Pipelines does not deploy Gitea web servers. Red Hat severity: Important — CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
Weakness: CWE-266. Red Hat lists OpenShift Pipelines as not affected.
