- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.32% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 25.3% of scored records. A rank, not a probability.
- NVD base score
- 7.7 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation
For standalone RNP users: Upgrade to RNP 0.18.1 when available. For distributions that have packaged 0.18.0: Please update to 0.18.1 when released, or consider providing 0.17.1 as an interim option. For Thunderbird packages using system RNP: If your Thunderbird package is built with system RNP support and RNP 0.18.0 is installed, update RNP to 0.18.1 or 0.17.1. Consider whether Thunderbird should continue using system RNP or switch to bundled RNP. For all other users: Users who encrypted sensitive data using RNP 0.18.0 (standalone or via Thunderbird with system RNP 0.18.0) should re-encrypt that data with RNP 0.18.1 or 0.17.1 based on their security requirements.
