CVE-2026-74870 openssl_encrypt before 1.4.8 Hardware Pepper Information Disclosure

opensslencrypt pip versions = 1.4.7 contain an information exposure vulnerability where the 'hsm fido2-test' and 'hsm onlykey-test' diagnostic commands unconditionally print the full derived hardware pepper as hex to stdout/stderr cryptcli.py, handlehsmcommand. The printed value can persist in...

CVE-2026-74871 openssl_encrypt before 1.4.6 KDF Bypass via Sequential-XOR

opensslencrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password...

CVE-2026-74879: Generation of Error Message Containing Sensitive Information

opensslencrypt versions before 1.4.0 contain an information disclosure vulnerability in the /ready endpoint that returns full database exception strings to unauthenticated callers. Attackers can trigger database errors to extract sensitive information including hostnames, IP addresses, connection...

CVE-2026-74880: Use of GET Request Method With Sensitive Query Strings

opensslencrypt versions before 1.4.0 accept refresh tokens as URL query parameters in keyserver and telemetry server routes. Attackers can extract tokens from server logs, proxy logs, browser history, and HTTP Referer headers to gain unauthorized access...

CVE-2026-74883: Protection Mechanism Failure

opensslencrypt versions before 1.4.0 contain a sandbox bypass vulnerability where the plugin sandbox fails to restrict alternative file access methods like pathlib.Path and io.open. Attackers can import pathlib or io modules to read and write arbitrary files, completely bypassing the restrictedop...

CVE-2026-74885: Improper Output Neutralization for Logs

opensslencrypt versions before 1.4.0 contain a logging bug in restorehiddenmodules that logs module counts after clearing, always showing zero restored modules and corrupting audit trails. Additionally, a race condition exists between module hiding and import hook installation where another threa...

CVE-2026-74890: Insufficient Verification of Data Authenticity

opensslencrypt versions before 1.4.0 contain an authentication bypass vulnerability in CamelliaCipher that disables HMAC tag generation and verification when the PYTESTCURRENTTEST environment variable is set. Attackers with code execution can set this environment variable to produce unauthenticat...

CVE-2026-74891: Use of Hard-coded Credentials

opensslencrypt versions before 1.4.0 contain hardcoded database credentials in standalone server configuration files. Attackers on the same network can access PostgreSQL databases using well-known default credentials to retrieve sensitive data...

CVE-2026-74894: Improper Authentication

opensslencrypt before 1.4.0 contains an authentication bypass vulnerability in the verifyapitoken function that accepts any non-empty Bearer token string without validation. Attackers can upload arbitrary public keys, enumerate all keys, and revoke keys belonging to any user by providing any Bear...

CVE-2026-74892: Use of Hard-coded Credentials

opensslencrypt versions before 1.4.0 contain a hardcoded default secret key in the standalone telemetry server configuration that is used for API key hashing. Attackers who know this default value can predict or forge API key hashes to compromise telemetry API authentication...

CVE-2026-74896: Protection Mechanism Failure

opensslencrypt versions before 1.4.0 contain a sandbox escape vulnerability in the DangerousPatternVisitor AST analyzer that fails to detect dunder attribute traversal techniques. Attackers can use class, bases, subclasses, and globals chains to access restricted functions and execute arbitrary...

CVE-2026-74899: Improper Neutralization of Directives in Dynamically Evaluated Code

opensslencrypt versions before 1.4.0 contain a sandbox escape vulnerability in IsolatedPluginExecutor that exposes Python type objects in restricted exec builtins. Attackers can traverse the Python class hierarchy via class.mro.subclasses to access system functions and execute arbitrary OS comman...

CVE-2026-74900: Unchecked Error Condition

opensslencrypt versions before 1.4.0 contain a critical vulnerability in pqc.py where KEM decapsulation failures silently fall back to simulation mode, generating a deterministic shared secret from only 16 bytes of the private key and publicly available encapsulated key data. Attackers who obtain...

CVE-2026-74875: Insufficient Verification of Data Authenticity

opensslencrypt versions before 1.4.0 silently skip JSON schema validation when the jsonschema library is not installed, allowing malformed metadata to be accepted. Attackers can remove the jsonschema package or supply unknown metadata format versions to bypass all schema checks and process...

CVE-2026-74881: Permissive Cross-domain Policy with Untrusted Domains
