03 Exploitation and scoring
- Exploitation
- Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
- SSVC decision
- ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
- EPSS probability
- 0.19% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 8.5% of scored records. A rank, not a probability.
- NVD base score
- 7.2 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation
No fixed release as of 2026-10-11. A community fix exists as VeraCrypt pull request #1866 (commit 000bcf4): on dismount, explicitly shut down the auxiliary FUSE-T service through an authenticated control endpoint and wait for it to terminate before reporting the dismount as complete. The maintainer described the same approach in issue #1779. The macFUSE build of VeraCrypt is unaffected.
