⚠️ Risk & Real-World Impact
Worst Case
An attacker gains full access to a user's password vault, leading to credential theft, data breaches, and further compromise of accounts and systems.
Likely Case
Attackers trick users into creating or importing malicious vault entries, resulting in session hijacking, data exfiltration, or phishing attacks within the vault interface.
If Mitigated
With proper input sanitization and user awareness, the risk is reduced to minimal, preventing execution of malicious scripts and protecting vault integrity.
🎯 Exploit Status
Exploitation requires user interaction (e.g., clicking a malicious entry) and may involve social engineering; no public proof-of-concept is known, but the vulnerability is straightforward to abuse.
