02 Description
Infinite recursion (CPU denial-of-service) in JOSE.JWK.shared_secret/2 on mismatched key types
03 Exploitation and scoring
- Exploitation

- Not assessed by CISA
- EPSS probability
- 0.13% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 3.0% of scored records. A rank, not a probability.
