CVE-2025-59031

Name of the Vulnerable Software and Affected Versions Dovecot versions prior to 2.4.3

Description Dovecot includes a script for converting attachments to text that improperly handles zip-style attachments. An attacker could leverage specially crafted OOXML documents to cause unintended files on the system to be indexed, potentially leading to their inclusion in Full-Text Search (FTS) indexes. The issue relates to the unsafe handling of zip-style attachments during the attachment-to-text conversion process. No publicly available exploits are known at this time.

Recommendations Do not use the provided script for attachment to text conversion. Instead, utilize an alternative solution such as FTS tika.
