CVE-2026-85199: Eclipse Foundation Eclipse advisory

Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.

What it is

Eclipse aeriOS Self-orchestrator versions prior to 1.2.1 contain a path traversal vulnerability in the REST API. User-controlled identifiers used to create, update, or delete Self-orchestrator resources were incorporated into filesystem paths without adequate validation or sanitization. An unauthenticated remote attacker able to access the Self-orchestrator API could therefore supply specially crafted identifiers containing path traversal sequences to write or delete JSON files outside the intended application directories, subject to the filesystem permissions of the Self-orchestrator process. The impact is increased by the absence of authentication on the affected API and by the container running with elevated privileges in the affected deployment configuration. The issue has been addressed in version 1.2.1 by introducing validation and sanitization of user-controlled identifiers before they are used to construct filesystem paths, preventing path separator characters from being used to escape the intended directories.

Description quoted from the CVE record (assigned by eclipse, published 2026-09-03).

Weakness: CWE-22 Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’); CWE-23 Relative path traversal; CWE-206 Observable internal behavioral discrepancy

How it can be exploited

Exploitable over the network with low attack complexity with no special attack requirements needing no privileges and no user interaction. Impact: confidentiality none, integrity high, availability high. CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N

CISA assessment (SSVC): CISA has no evidence of exploitation. Automatable: yes. Technical impact: partial.
