CVE-2026-88015

Описание

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, backend/local with --links or links=true exposes symlink targets as .rclonelink objects, and fs.RangeOption.Decode can pass an unchecked positive Range start through Object.Open and openTranslatedLink. The function slices the target string as linkdst[offset:], so a Range start larger than the target length causes a deterministic slice-bounds panic when lib/http/serve exposes the object through HTTP or WebDAV. Go net/http normally recovers the panic per connection, causing request-level denial of service rather than terminating the entire process. This issue is fixed in version 1.75.1.

A flaw was found in rclone. When rclone is configured with backend/local and links=true, it exposes symlink targets as .rclonelink objects. A remote attacker can send a crafted Range request with an unchecked positive Range start, leading to a deterministic slice-bounds panic. This issue results in a request-level Denial of Service (DoS), where individual connections can be disrupted.
