CVE-2026-8757
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in adenhq hive up to 0.11.0. This affects the function _read_events_tail of the file core/framework/server/routes_sessions.py of the component Delete Request Handler. Performing a manipulation results in path traversal. The attack may be initiated remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA path traversal vulnerability exists in adenhq hive up to version 0.11.0 in the _read_events_tail function within core/framework/server/routes_sessions.py of the Delete Request Handler. Remote attackers can manipulate path inputs to access files outside the intended directory, achieving a critical CVSS 9.1 severity due to the network-exploitable, low-complexity attack vector.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Adenhq Hive installationLocate the Adenhq Hive installation directory and check for version metadata files (such as a version.py, __init__.py with version info, setup.py, or package.json) or run a command like 'pip show adenhq-hive' or 'pip list | grep -i adenhq' to retrieve the installed version number.Affected if The installed version is 0.11.0 or any version lower than 0.11.0.
-
Locate vulnerable source fileSearch for the file core/framework/server/routes_sessions.py within the Adenhq Hive installation directory.Affected if The file exists in the installation, confirming the presence of the vulnerable code path.
-
Verify Delete Request Handler is exposedExamine the application configuration or routing setup to determine if the Delete Request Handler endpoint is exposed and accessible over the network (check for DELETE HTTP method routes in the routes_sessions.py file or related routing configuration).Affected if The Delete Request Handler is enabled and accessible via HTTP/HTTPS network access.
-
Confirm path input capabilityReview the application's API endpoints or web interface to verify that user-supplied path parameters can be passed to the Delete Request Handler (look for endpoints accepting path or file parameters in the routes_sessions.py or related handler code).Affected if The Delete Request Handler accepts path input from users without requiring authentication or additional privileges.
Your environment is affected if Adenhq Hive version 0.11.0 or lower is installed, the routes_sessions.py file exists, and the Delete Request Handler is exposed with user-controllable path input.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and sanitization on all path parameters in the Delete Request Handler, using allowlist validation or canonicalization checks to prevent directory traversal sequences (../). Apply proper file access controls and ensure paths resolve within intended boundaries.
