A flaw was found in Dovecot. An attacker can exploit this by using specially crafted OOXML (Office Open XML) documents that are unsafely handled by a provided script designed for attachment to text conversion. This can lead to unintended files on the system being indexed and subsequently exposed in Full Text Search (FTS) indexes, resulting in information disclosure.

Description OSIDB Bzimport 2026-03-27 09:02:05 UTC 
Dovecot has provided a script to use for attachment to text conversion. This script unsafely handles zip-style attachments. Attacker can use specially crafted OOXML documents to cause unintended files on the system to be indexed and subsequently ending up in FTS indexes. Do not use the provided script, instead, use something else like FTS tika. No publicly available exploits are known.
