Threats Tagged 'cve-2026-20800'

CVE-2026-20800 is a medium-severity vulnerability in the Gitea Open Source Git Server's notification API, where repository access permissions are not re-validated when returning notification details. This flaw allows users who have had their access to private repositories revoked to still view issue and pull request titles through previously received notifications. The vulnerability impacts confidentiality but does not affect integrity or availability, and it requires the attacker to have had prior access to the repository. No user interaction is needed once access is revoked, and exploitation can be performed remotely with low complexity. There are no known exploits in the wild, and no patches have been released yet. European organizations using Gitea for private repository management should be aware of potential sensitive information exposure risks. Mitigation involves auditing notification access controls, restricting notification content, and monitoring user access revocations closely. Countries with significant open source development communities and high adoption of Gitea, such as Germany, France, and the Netherlands, are more likely to be affected.
