Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

TeamPass 2.1.27 and earlier (package nilsteampassnet/teampass) stores shared password vault entries in a recoverable format, so all shared passwords can be recovered on the server side. The source describes exploitation as possible through any flaw that bypasses authentication or role assignment, which could lead to leakage of shared passwords. No fixed version is listed, so check for an update from the vendor.
