EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 59% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by supplying a crafted files-from entry. Attackers can trigger the vulnerability against a read-only rsync daemon module by providing a files-from entry containing both an interior and trailing backslash, causing the add_implied_include() function to under-count the trailing backslash when sizing the destination buffer.
