Vinchin Backup & Recovery 9.0.0.86562 Stack Buffer Overflow via ModuleHandShake

Published Jul 9, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
Vinchin Backup & Recovery through 9.0.0.86562 contains a stack buffer overflow vulnerability in the ModuleHandShake function of the agentlink_server service that allows unauthenticated remote attackers to overwrite the saved return address by supplying an oversized _listen_uuid field that is measured via strlen() and copied without bounds checking into a fixed-length stack buffer using strcpy(). Attackers can send a crafted request with a malicious _listen_uuid value to corrupt the stack and achieve process crash or potential control flow hijack without requiring authentication.
