CVE-2026-53604

CVE-2026-53604 - UNKNOWN Severity Vulnerability

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.3.8, the web handler renderMobileBundle passes the real *pki.CAResolver directly into mobilebundle.Build. Inside Build, resolver.LoadByID decrypts the CA's ed25519 private key into a *pki.CAManager, but Build never calls CAManager.Wipe() on any return path. As a result, when a mobile-bundle request goes through the web UI and Build returns — especially on error (missing network, invalid prefix, DB error, signing failure) — the plaintext CA private key remains on the Go heap, unwiped, until garbage collection. An attacker able to read process memory (core dump, swap, memory-scraping) can recover the CA signing key, which would allow minting arbitrary host certificates for the mesh. The API handler already does this correctly: it loads the CAManager, defer caMgr.Wipe(), and wraps it in caManagerResolver. Only the web path is affected. This issue has been patched in version 0.3.8.

CVE-2026-75137

CVE-2026-75137 - MEDIUM Severity Vulnerability

UpSignOn for Windows before 7.19.0 contains a sensitive data exposure vulnerability that allows local attackers to recover cleartext vault data from process memory even after the application has been locked. Attackers can use the PROCESS_VM_READ permission to read the memory space of UpSignOn.exe and extract sensitive fields including entry names, URLs, usernames, passwords, TOTP secrets, and notes.

CVE-2026-75135

CVE-2026-75135 - MEDIUM Severity Vulnerability

UpSignOn for Windows before 7.19.0 contains a sensitive data exposure vulnerability that allows local attackers to recover the master password and decrypt vault contents by reading a retained backup key from the process memory of UpSignOn.exe, even after the vault has been re-locked. Attackers can extract the backup key from process memory to decrypt the encrypted master password backup stored in v6-vault1.DATA.txt, then use the recovered master password to decrypt the main vault and export all password manager entries in cleartext.
