Security readout for executives and security teams
Plain-English summary
CVE-2026-25591 affects QuantumNous New API, an LLM gateway and AI asset management system. Authenticated users can abuse token search to force expensive database queries, potentially making the service unavailable. The advisory says versions before 0.10.8-alpha.10 are affected and that 0.10.8-alpha.10 contains the patch.
Executive priority
Prioritize patching if New API supports production AI workflows, shared tenant environments, or externally reachable portals. The main business risk is service disruption from authenticated misuse, which could affect AI gateway availability and downstream applications.
Technical view
The /api/token/search endpoint concatenates user-controlled keyword and token parameters into SQL LIKE clauses without escaping LIKE wildcards. This can trigger resource-intensive database searches and denial of service. The issue is classified as CWE-943 with CVSS 4.0 score 7.1, reflecting network access, low complexity, low privileges, no user interaction, and high availability impact.
Likely exposure
Exposure is limited to deployments of QuantumNous new-api before 0.10.8-alpha.10 where users can authenticate and reach /api/token/search. Internet-facing admin or tenant portals increase operational risk, but internal-only deployments can still be affected by any low-privileged account with access.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked in KEV. Exploitation requires authentication but is low complexity once access exists. The documented impact is denial of service through database resource exhaustion, not confirmed data theft or code execution.
Researcher notes
Evidence supports an authenticated SQL LIKE wildcard injection denial-of-service condition in token search. The patch reference is public, but this assessment avoids exploit mechanics. No source in the bundle confirms exploitation in the wild, data compromise, privilege escalation, or unauthenticated access.
Mitigation direction
- Upgrade QuantumNous new-api to 0.10.8-alpha.10 or later.
- Restrict access to token search to trusted users where operationally possible.
- Monitor database and application resource usage until patched.
- Review vendor advisory and release notes for deployment-specific guidance.
Validation and detection
- Inventory QuantumNous new-api deployments and identify versions below 0.10.8-alpha.10.
- Confirm whether authenticated users can access /api/token/search.
- Review logs for unusual token search activity and database load spikes.
- Verify the patched release is deployed after remediation.
