5.9
MEDIUM
CVSS 3.1
EPSS 0.02%
描述
## Summary The LTI 1.1 validator stores OAuth nonces in a class-level dictionary that grows without bounds. Nonces are added before signature validation, so an attacker with knowledge of a valid consumer key can send repeated requests with unique nonces to gradually exhaust server memory, causing a denial of service. ## Patches - upgrade jupyterhub-litauthenticator to 1.6.3
