03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.

- 0.57% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 44.7% of scored records. A rank, not a probability.
- NVD base score
- 2.1 (CVSS v4.0), scored by the NVD independently of the CNA.
