CVE-2026-22675 — Ocsinventory-Ng Ocs Inventory Server security vulnerability
OCS Inventory NG Server version 2.12.3 and prior contain a stored cross-site scripting vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript by submitting malicious User-Agent HTTP headers to the /ocsinventory endpoint. Attackers can register rogue agents or craft requests with malicious User-Agent values that are stored without sanitization and rendered with insufficient encoding in the web console, leading to arbitrary JavaScript execution in the browsers of authenticated users viewing the statistics dashboard.

Cross-site scripting and unsafe browser output
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
- Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
- Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.
Remediate safely
- Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
- Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
- Update affected rendering components and add tests for every output context using inert sentinel markup.
