MediumCVSS 6.3Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
A flaw in migration-planner. Insufficient validation of the AgentStatusUpdate.CredentialUrl field allows an authenticated attacker to store a malicious javascript: URL. When a victim views this URL in the Hybrid Cloud Console, it can lead to Cross-Site Scripting (XSS), enabling script execution in the victim's session and potentially disclosing sensitive information.
Risk Assessment
The risk includes user session hijacking, data theft, and unauthorized actions in the victim's context.
Recommendation
Update migration-planner to a patched version and validate/sanitize URL fields before storing and displaying them.
