UBUNTU-CVE-2026-79778

rclone before v1.75.0 contains a denial of service vulnerability in the WebDAV TUS creation handler that dereferences a nil response before checking for transport errors. A malicious or compromised configured endpoint can reset connections during TUS uploads to trigger a panic that terminates...

UBUNTU-CVE-2026-79775

rclone versions = v1.72.0 and = v1.74.4 fixed in v1.75.0 contain multiple denial-of-service vulnerabilities in the archive backend's SquashFS parser, which relies on the github.com/diskfs/go-diskfs dependency. The parser fails to validate attacker-controlled superblock and metadata values before...

UBUNTU-CVE-2026-79781

rclone serve s3 before 1.74.4 contains a path traversal vulnerability that allows attackers to read and overwrite root-level files by using dot-dot segments in S3 object keys. Attackers can send requests with object keys like ../root-secret.txt to escape the bucket namespace and access files in t...

CVE-2026-79783

rclone before 1.74.4 fails to mask special permission bits when applying source-supplied mode metadata in the local backend, allowing attackers to set setuid/setgid bits on attacker-controlled files. When copying with metadata preservation from an untrusted remote, attackers can plant a setuid...

UBUNTU-CVE-2026-79776

rclone before 1.75.0 mounts the pprof debug handler as its own router route, bypassing the fail-closed authentication rule in the main handler. Attackers can access the /debug/pprof/cmdline endpoint unauthenticated to retrieve the full process argv including backend credentials...

UBUNTU-CVE-2026-79777

rclone before v1.75.0 includes full Go stack traces in RC API error responses when panics occur. Attackers can trigger panics to leak internal file paths, module versions, goroutine states, and memory addresses...

UBUNTU-CVE-2026-79780

rclone before v1.75.0 fails to sanitize IBM IAM bearer tokens and SSE-C encryption keys during S3 redirect callbacks, allowing credentials to be preserved across scheme or host changes. Attackers observing network traffic from a trusted endpoint can capture reusable IBM IAM tokens on same-host...

CVE-2026-79782

rclone before 1.74.4 fails to strip the X-Amz-Security-Token header when an S3 redirect changes scheme from HTTPS to HTTP on the same host. Attackers can intercept plaintext HTTP traffic to capture AWS STS session tokens sent in request headers...

CVE-2026-79782 rclone before 1.74.4 Security Token Disclosure via HTTPS to HTTP Redirect

rclone before 1.74.4 fails to strip the X-Amz-Security-Token header when an S3 redirect changes scheme from HTTPS to HTTP on the same host. Attackers can intercept plaintext HTTP traffic to capture AWS STS session tokens sent in request headers...

CVE-2026-79782 rclone before 1.74.4 Security Token Disclosure via HTTPS to HTTP Redirect

CVE-2026-79783 rclone before 1.74.4 Privilege Escalation via setuid Metadata

rclone before 1.74.4 fails to mask special permission bits when applying source-supplied mode metadata in the local backend, allowing attackers to set setuid/setgid bits on attacker-controlled files. When copying with metadata preservation from an untrusted remote, attackers can plant a setuid...

CVE-2026-79782

rclone before version 1.74.4 does not strip the X-Amz-Security-Token header when an S3 redirect changes the scheme from HTTPS to HTTP on the same host. An attacker positioned to intercept the resulting plaintext HTTP traffic can capture AWS STS session tokens transmitted in request headers, poten...

CVE-2026-79783

rclone before 1.74.4 contains a privilege escalation vulnerability in its local backend . The root cause is a failure to mask special permission bits (setuid/setgid) when applying source-supplied mode metadata. An attacker who controls a remote source can plant a setuid binary by copying files wi...
