Unverified50% confidenceFactExact time
Due to the flawed end-marker matching logic, when a PEM private key's end marker was mistakenly written as `END CERTIFICATE`, the library masked only the header, and the base64-encoded private key body streamed through directly in plaintext, with the leaked body able to reconstruct a usable private key.

UnverifiedIn implementations before version 0.7.9, llm-stream-guardrails held PEM private keys via the `BEGIN PRIVATE KEY` marker, but determined the end by whether any labeled `END` line appeared, rather than requiring the label to match exactly.75% similarUnverifiedv2.1.286 fixes multiple key redaction issues, including no longer exposing credential values when Bearer or Basic appears before the key name in error messages, and the issue of percent-encoded Bearer tokens being only partially masked.72% similarUnverifiedThe architecture of Ledger Recover logically demonstrates that private key material can leave the Secure Element in some form, contradicting Ledger's previous official statement that private keys never leave the device.70% similarUnverifiedUnder a secure boot mechanism, even if an attacker modifies the firmware code, as long as the private key is not leaked, the modified firmware cannot pass signature verification.70% similarUnverifiedThe root cause of keychain migration failure is that the encryption key is sealed within the source device's Secure Enclave and cannot be exported, leaving the target device unable to provide the same hardware key for decryption68% similar
