CVE-2026-81686

opensslencrypt 1.4.x before 1.4.9 contains an optional D-Bus crypto service whose org.freedesktop.DBus.Properties.Set method performs neither a polkit authorization check nor value validation. Any local user on the system bus can call Set without authorization and set MaxConcurrentOperations to...

CVE-2026-81685

opensslencrypt versions before 1.4.9 fail to sanitize recovery-slot metadata in the desktop GUI, allowing attackers to inject control characters and line separators into the irreversible-removal confirmation dialog. Attackers can craft encrypted files with malicious slot identifiers containing bi...

CVE-2026-81687

opensslencrypt versions before 1.4.9 fail to enforce a time ceiling on key derivation function iteration counts specified in file metadata. Attackers can craft files with extremely high KDF iteration counts to consume CPU resources for unbounded periods before password verification occurs...

CVE-2026-81691

opensslencrypt versions before 1.4.9 fail to validate server URLs in login and registerwithemail functions, accepting unencrypted http:// URLs and unconfigured hosts. Attackers on the network path can intercept cleartext credentials including clientid, passwords, and JWTs to achieve full keyserve...

CVE-2026-81682

opensslencrypt versions before 1.4.9 contain an insecure file permissions vulnerability in the desktop GUI that writes decrypted plaintext with world-readable default permissions. Attackers can read decrypted output files created by the GUI as unprivileged local users on multi-user systems...

CVE-2026-81680

opensslencrypt versions before 1.4.9 fail to authenticate recovery-slot presence in envelope-format encrypted files, allowing attackers to remove recovery slots without re-encrypting the payload. Attackers can modify the file header to delete recovery-slot fields and bypass authentication, silent...

EUVD-2026-67071

opensslencrypt before 1.4.9 fails to validate KDF cost parameters in encrypted file metadata and keystore headers, allowing attackers to trigger unbounded memory allocation. Attackers can craft malicious encrypted files declaring arbitrarily large Argon2, scrypt, or balloon KDF parameters to...

CVE-2026-81721 openssl_encrypt before 1.4.9 Denial of Service via KDF

opensslencrypt before 1.4.9 fails to validate KDF cost parameters in encrypted file metadata and keystore headers, allowing attackers to trigger unbounded memory allocation. Attackers can craft malicious encrypted files declaring arbitrarily large Argon2, scrypt, or balloon KDF parameters to...

CVE-2026-81721

openssl_encrypt before 1.4.9 fails to validate KDF cost parameters (Argon2, scrypt, or balloon) in encrypted file metadata and keystore headers. An unauthenticated attacker over the network can craft a malicious encrypted file declaring arbitrarily large KDF parameters, triggering unbounded memor...

CVE-2026-81721 openssl_encrypt before 1.4.9 Denial of Service via KDF

opensslencrypt before 1.4.9 fails to validate KDF cost parameters in encrypted file metadata and keystore headers, allowing attackers to trigger unbounded memory allocation. Attackers can craft malicious encrypted files declaring arbitrarily large Argon2, scrypt, or balloon KDF parameters to...

EUVD-2026-67070

opensslencrypt before 1.4.9 fails to validate the memorycost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive...

CVE-2026-81720

openssl_encrypt before 1.4.9 fails to validate the memory_cost parameter found in identity file protection blocks. Because the value is passed unboundedly into Argon2 key derivation, an attacker with write access to local identity stores can craft a malicious identity file with an excessive memor...

CVE-2026-81720 openssl_encrypt before 1.4.9 Denial of Service via Unbounded Argon2

opensslencrypt before 1.4.9 fails to validate the memorycost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive...

CVE-2026-81720 openssl_encrypt before 1.4.9 Denial of Service via Unbounded Argon2

opensslencrypt before 1.4.9 fails to validate the memorycost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive...

opensslencrypt before 1.4.9 executes untrusted third-party plugins with insufficient controls: the plugin signature policy defaulted to WARN, so an unsigned/unverifiable non-built-in plugin was compiled and executed in the host process at import time, before the runtime sandbox is installed. The...

CVE-2026-81719 openssl_encrypt before 1.4.9 Remote Code Execution via Plugin

opensslencrypt before 1.4.9 executes untrusted third-party plugins with insufficient controls: the plugin signature policy defaulted to WARN, so an unsigned/unverifiable non-built-in plugin was compiled and executed in the host process at import time, before the runtime sandbox is installed. The...

CVE-2026-81719

openssl_encrypt versions before 1.4.9 are vulnerable to arbitrary code execution via third-party plugins. The plugin signature policy defaulted to WARN , allowing unsigned or unverifiable non-built-in plugins to be compiled and executed in the host process at import time—before the runtime sandbo...

EUVD-2026-67067

opensslencrypt pip package openssl-encrypt before 1.4.9 contains two weaknesses in the portable USB drive feature, whose threat model treats the removable drive as untrusted attacker with physical write access. USBDriveCreator.verifyintegrityfile only validates files listed in the manifest, so...

EUVD-2026-67068

opensslencrypt versions before 1.4.9 use under-parameterized PBKDF2-HMAC-SHA256 with only 100,000 iterations to protect PQC keyfile private keys and 10,000 iterations for dual-encryption file-password verification. Attackers who obtain keyfiles or encrypted files can brute-force wrapping password...
