Published Oct 1, 2026 CVSS 3.1 · 9.1 Critical EPSS < 1% KEV · Not listed
Description
deeptutor 1.4.0 contains an authorization bypass through a user-controlled object identifier in TutorBotManager.write_bot_file. A remote caller can enumerate bot IDs and overwrite another bot's whitelisted control files through the HTTP tutorbot file route.

Analysis

AI-generated

Technical impact

The vulnerability resides in DeepTutor 1.4.0's TutorBotManager.write_bot_file function, which allows a remote user to supply a user‑controlled object identifier. This leads to an authorization bypass that permits enumeration of bot IDs and overwriting of another bot's whitelisted control files via the HTTP tutorbot file route. As a result, an attacker can modify privileged configuration files that govern bot behavior, potentially enabling execution of arbitrary actions or unauthorized bot commands.

Affected Systems

Affected is DeepTutor version 1.4.0. No additional vendor or product versions are documented in the CVE.

Risk and Exploitability

The flaw can be exploited remotely over HTTP without authentication, enabling malicious enumeration and alteration of protected files. The EPSS score of < 1% indicates low probability of exploitation, and the vulnerability is not listed in the CISA KEV catalog. A CVSS score of 9.1 indicates high severity, and the ability to overwrite whitelisted control files represents a significant risk to integrity and operational control of the system.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Implement strict authentication and authorization checks on the HTTP tutorbot file route to prevent unauthenticated write access.
  • Validate and sanitize all object identifiers before use in file write operations, ensuring only system‑controlled identifiers are accepted.
  • Apply vendor‑issued updates or patches as soon as they become available to address the authorization bypass flaw.
