CVE-2025-3930 — Lack of JWT Expiration after Log Out in Strapi

Strapi uses JSON Web Tokens (JWT) for authentication. After logout or account deactivation, the JWT is not invalidated, which allows an attacker who has stolen or intercepted the token to freely reuse it until its expiration date (which is set to 30 days by default, but can be changed). The existence of /admin/renew-token endpoint allows anyone to renew near-expiration tokens indefinitely, further increasing the impact of this attack. This issue has been fixed in version 5.24.1.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.5% (30-day exploitation probability)+6
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Strapi Strapi).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?

CVE-2025-3930 is "Lack of JWT Expiration after Log Out in Strapi", rated Medium. It affects Strapi (Strapi); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.3 describes technical severity. EPSS 0.52% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
