CVE-2026-79777
Description
A flaw was found in rclone. Attackers can exploit this vulnerability by triggering panics in the RC API error responses. This can lead to the disclosure of sensitive internal information, such as file paths, module versions, goroutine states, and memory addresses, potentially aiding further attacks.
Statement
A flaw was found in rclone. The Remote Control (RC) API can include sensitive information such as internal paths, configuration details, or error context in error responses. An authenticated administrator with access to the RC API can observe this information, which may aid in further attacks against the system.
Mitigation
Restrict access to the rclone RC API to trusted networks and administrators only. Use the --rc-allow-origin and --rc-user/--rc-pass flags to enforce authentication. Where possible, disable the RC API entirely if not required for operations.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
CVSS v3 Score Breakdown

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Often this will either reveal sensitive information which may be used to launch another, more focused attack or disclose private information stored in the server. For example, an attempt to exploit a path traversal weakness (CWE-22) might yield the full pathname of the installed application. In turn, this could be used to select the proper number of ".." sequences to navigate to the targeted file. An attack using SQL injection (CWE-89) might not initially succeed, but an error message could reveal the malformed query, which would expose query logic and possibly even passwords or other sensitive information used within the query.
