Detailsinfo

A vulnerability classified as problematic has been found in Gitpod (the affected version is unknown). Affected is an unknown code of the component Link Handler. The manipulation with an unknown input leads to a insertion of sensitive information into sent data vulnerability. CWE is classifying the issue as CWE-201. The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor. This is going to have an impact on confidentiality. CVE summarizes:

Gitpod is a developer platform for cloud development environments. In versions before main-gha.33628 for both Gitpod Classic and Gitpod Classic Enterprise, OAuth integration with Bitbucket in certain conditions allowed a crafted link to expose a valid Bitbucket access token via the URL fragment when clicked by an authenticated user. This resulted from how Bitbucket returned tokens and how Gitpod handled the redirect flow. The issue was limited to Bitbucket (GitHub and GitLab integrations were not affected), required user interaction, and has been mitigated through redirect handling and OAuth logic hardening. The issue was resolved in main-gha.33628 and later. There are no workarounds.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2025-55750 since 08/15/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim.
