CVE-2026-116634: OmniRoute 3.8.50 before 3.8.52 Missing Authentication via /api/sync/tokens

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.

Generated by VEDAS. Scores as of 2026-11-01 19:19 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.

What it is

OmniRoute 3.8.50 before 3.8.52 contains a missing authentication vulnerability that allows unauthenticated attackers to issue sync tokens via POST /api/sync/tokens when requireLogin is disabled. Attackers can use the issued token against GET /api/sync/bundle to retrieve decrypted provider credentials and plaintext API keys, with tokens persisting after login is re-enabled.

Description quoted from the CVE record (assigned by VulnCheck, published 2026-10-26).

Weakness: Missing Authentication for Critical Function

How it can be exploited

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

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

OmniRoute - Missing Authentication

OmniRoute 3.8.50 before 3.8.52 exposes POST /api/sync/tokens without authentication when requireLogin is disabled, letting an unauthenticated remote attacker issue a legacy “open” sync token. The token can then be presented to GET /api/sync/bundle to retrieve decrypted provider credentials and plaintext API keys. This template confirms the missing-authentication token issuance without reading any secrets.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (POST /api/sync/tokens); it decides using status, word matchers. Severity in the template: high. Marked as not yet verified against a live vulnerable target.
