Loading vulnerability…
CVE-2026-53604 is a sensitive-data exposure vulnerability in nebula-mesh affecting web mobile-bundle code paths. The flaw arises because the certificate authority private key loaded into memory is not reliably wiped after use, including on error-return paths. In the vulnerable implementation, the loaded CA manager remains in process memory instead of being zeroized, allowing the plaintext CA signing key to persist longer than intended. The issue is corrected by ensuring the loaded CA manager is wiped on all return paths and by keeping the wipe routine idempotent.
