CVE-2026-107371: Missing Verification of auth_time Claim in auth0.js
Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Auth0 auth0.js 10.3.0.
Low priority for now. Upgrade to Auth0 auth0.js 10.3.0 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
When the authorize() method is called with a maxAge parameter, the auth0.js library does not validate the auth_time claim in the resulting ID token against the requested maxAge value. As a result, an application may process an ID token that represents an authentication event older than the requested maximum age.
