CVE-2026-68509

Read full description

FairEmail is a fully featured, open source, privacy-friendly email app for Android. Prior to 1.2325, shared attachment handling does not adequately sanitize an attacker-controlled filename before constructing its destination path. A local attacker-controlled app can therefore supply path components that escape the intended shared attachment directory and overwrite or corrupt files in the FairEmail private data directory, including account or message databases. Exploitation requires app lock using PIN or biometric authentication and user interaction to unlock FairEmail. This issue is fixed in version 1.2325.

Evidence context and dated references

Reality is general threat/review priority, combining observed exploitation, CVSS severity and fresh EPSS. Evidence confidence is separate. This is not calibrated risk, a victim count or an asset-specific assessment. A range reflects missing numeric inputs. Published 1 days ago. Exploitation evidence usually takes weeks to show up: a low reality score can mean there is no data yet, not that the flaw is mild.
