Technical details
The APITokenLogMiddleware in Plane prior to 1.4.0 logged API keys in plaintext to the database. An attacker with low privileges and access to application logs could extract these API keys. The fix replaces plaintext logging with HMAC-SHA256 hashing of tokens and redacts sensitive headers (X-Api-Key, Authorization, Cookie) from logs.
