Unauthenticated mail read and modification
Published Feb 9, 2026 · Updated Feb 9, 2026
Missing authentication in HGiga C&Cm@il package olln-base before 7.0-978 allows remote attackers to read and modify any user's mail. HGiga and TWCERT/CC have not published the affected endpoint or the authentication check omitted when mail operations process requests. No credentials or user interaction are required, and exploitation compromises every user's stored-mail confidentiality and integrity without a reported service interruption.
