02 Description
ruby-saml vulnerable to Remote Denial of Service (DoS) with compressed SAML responses
03 Exploitation and scoring
- Exploitation

- EPSS probability
- 1.52% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 74.3% of scored records. A rank, not a probability.
- NVD base score
- 7.7 (CVSS v4.0), scored by the NVD independently of the CNA.
