This flaw permits the sandboxed application to read, write, or execute arbitrary files outside its confinement, undermining the isolation guarantees and enabling possible privilege escalation or data exfiltration.", "risk_and_exploitability": "The CVSS score of 6.5 indicates moderate severity. No EPSS score is available, and the vulnerability is not listed in the CISA KEV catalog. The exploit requires an application able to communicate with Dolphin via the FileManager1 protocol; this is typically a Flatpak or AppArmor confined application. Because the flaw permits arbitrary file system access beyond the sandbox boundaries, it can be used to read sensitive data or execute malicious code. The lack of a confirmed public exploit suggests the risk remains theoretical, but the flaw provides a clear pathway for privilege escalation that should be addressed promptly."}}}}, "created": "2026-04-28T09:16:40.287362+00:00", "title": "Dolphin Flatpak Confinement Bypass via FileManager1 Path Spoofing", "updated": "2026-04-28T12:45:31.387708+00:00", "vendors": ["kde", "kde$PRODUCT$dolphin"]}
