Cleartext Storage in a File or on Disk in TimelyBills <= 1.7.0 for iOS and versions <= 1.21.115 for Android allows attacker who can locally read users files obtain JWT tokens for users account due to insufficient cache clearing mechanisms. A threat actor can obtain sensitive user data by decoding the tokens as JWT is signed and encoded, not encrypted.
Weakness
The product does not properly “clean up” and remove temporary or supporting resources after they have been used.
