Technical Analysis
This vulnerability affects the OAuth Callback component in RooCodeInc Roo-Code versions 3.51.0 and 3.51.1, specifically in the file src/integrations/claude-code/oauth.ts. It results in sensitive information being transmitted in cleartext, which could be intercepted by remote attackers. The attack complexity is high, and no privileges or user interaction are required. Although exploit code is public, the vendor has archived the project and does not support it anymore.
Potential Impact
Sensitive information transmitted in cleartext can be intercepted by attackers with network access, potentially leading to information disclosure. However, the attack complexity is high and no privileges or user interaction are required. The product is no longer supported, so no official fixes or mitigations are provided by the vendor.
Mitigation Recommendations
No official patch or remediation is available since the vendor has archived the project and does not support it. Users are advised to discontinue use of Roo-Code and migrate to supported alternatives. Patch status is not yet confirmed — check the vendor advisory or project repository for any community-driven fixes or mitigations.
