CVE-2026-70461 is a heap-based out-of-bounds write in rsync versions 3.2.5 through 3.4.4. When processing a crafted files-from entry containing both an interior backslash and a trailing backslash, add_implied_include() under-counts the trailing backslash while calculating the destination-buffer size. Subsequent processing writes one attacker-controlled byte past the allocated heap buffer. The flaw is reachable remotely without authentication against a read-only rsync daemon module.
