Which versions of Zhoros SuperBin are affected by CVE-2026-50877?

Zhoros SuperBin v1.0.0 contains an unauthenticated remote directory traversal vulnerability enabling attackers to read and write arbitrary files on affected systems without credentials.

How to fix or mitigate CVE-2026-50877?

Within 24 hours: Identify all systems running Zhoros SuperBin v1.0.0 and implement network-level access restrictions, limiting connections to trusted internal sources only. Within 7 days: Deploy application-level input validation, implement strict file upload controls, and restrict service account privileges; initiate evaluation of alternative file management solutions. Within 30 days: Execute migration to alternative product or decommission Zhoros SuperBin v1.0.0 entirely, as no vendor patch is available to address the vulnerability.

DescriptionCVE.org

An issue in Zhoros SuperBin v1.0.0 allows attackers to execute a directory traversal via supplying files with names containing traversal characters.

AnalysisAI

Directory traversal in Zhoros SuperBin v1.0.0 allows remote unauthenticated attackers to read or write files outside intended directories by uploading files whose names contain traversal sequences such as '../'. The flaw stems from inadequate sanitization of user-supplied filenames during file handling operations. Publicly available exploit code exists via a referenced GitHub gist, though there is no public exploit identified as weaponized at scale and the vulnerability is not listed in CISA KEV.

Technical ContextAI

Zhoros SuperBin v1.0.0 is a file-sharing/pastebin-style application that processes uploaded files. The vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory, aka 'Path Traversal'), meaning the application uses untrusted input - specifically the filename supplied during upload - to construct a filesystem path without canonicalizing or stripping directory separators ('../', backslashes, or absolute path prefixes). When the server stores or retrieves files based on this attacker-controlled filename, it can resolve outside the intended storage directory, allowing reads or writes to arbitrary locations within the host filesystem permissions of the application process. The CPE record (cpe:2.3:a:n/a:n/a) is a placeholder, indicating MITRE did not normalize vendor/product into the official CPE dictionary at publication.

RemediationAI

No vendor-released patch identified at time of analysis - the only references are the NVD entry and a third-party PoC gist (https://gist.github.com/pyuysig/ed896b93637aa6501e5f80def198c626), with no vendor advisory or fixed version published. Affected operators should upgrade to a patched release once Zhoros publishes one; in the interim, apply compensating controls by placing SuperBin behind a reverse proxy or WAF rule that rejects upload requests whose filename parameter contains '../', '..\', URL-encoded variants (%2e%2e%2f), or absolute path prefixes ('/', drive letters), with the trade-off that legitimate filenames containing literal dots may be blocked. Additionally, run the SuperBin process under a dedicated low-privileged user chrooted or containerized to a dedicated upload directory so that successful traversal cannot reach sensitive system files (trade-off: requires deployment changes and may break features relying on shared paths). If the upload feature is non-essential, disable the upload endpoint entirely via webserver-level access control.
