Identifier	cpeApplicability	Submitted	db.gcve.eu details	Rationale
`CVE:CVE-2021-44143`	vulnerable	2026-06-08 05:36:45.014217	Details available A flaw was found in mbsync in isync 1.4.0 through 1.4.3. Due to an unchecked condition, a malicious or compromised IMAP server could use a crafted mail message that lacks headers (i.e., one that starts with an empty line) to provoke a heap overflow, which could conceivably be exploited for remote code execution.

`CVE:CVE-2021-3657`	vulnerable	2026-06-08 05:33:53.321625	Details available A flaw was found in mbsync versions prior to 1.4.4. Due to inadequate handling of extremely large (>=2GiB) IMAP literals, malicious or compromised IMAP servers, and hypothetically even external email senders, could cause several different buffer overflows, which could conceivably be exploited for remote code execution.

`CVE:CVE-2021-3578`	vulnerable	2026-06-08 05:33:52.867197	Details available A flaw was found in mbsync before v1.3.6 and v1.4.2, where an unchecked pointer cast allows a malicious or compromised server to write an arbitrary integer value past the end of a heap-allocated structure by issuing an unexpected APPENDUID response. This could be plausibly exploited for remote code execution on the client.
