Impact

A flaw in the Revoked API Token Handler of QuantumNous new‑api causes an attacker to force a session to expire by manipulating the /api/usage/token endpoint. The result is an unexpected loss of user authentication, disrupting normal service availability for legitimate users. The weakness is a session‑management issue (CWE‑613) that can be triggered remotely through crafted requests.

Affected Systems

QuantumNous new‑api component versions up to 1.0.0‑rc.15 are affected. Updating to 1.0.0‑rc.17 fixes the problem. No other software vendors or products are listed as affected.

Risk and Exploitability

The CVSS score of 5.3 indicates moderate severity. The EPSS score is not available, and the vulnerability is not in CISA KEV. The exploit is remote, relying on manipulation of authentication tokens via the exposed/unknown functionality at /api/usage/token. Because the flaw was publicly disclosed, it may be used by attackers seeking to disrupt user sessions.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade QuantumNous new-api to version 1.0.0‑rc.17, which contains the fix commit 0d5995eb63f8801d32eb32fbe74b75b68752bfa9.
  • If immediate upgrade is not possible, invalidate all current API tokens so any in‑use sessions are forced to re‑authenticate, mitigating the possibility of lingering valid sessions.
  • After applying the patch or token invalidation, review the Revoked API Token Handler configuration to ensure that session expiration is enforced automatically whenever a token is revoked, eliminating the remaining vulnerability window.
