  "details": "### Impact\nThis vulnerability affects **Cloudreve** instances that were **first deployed/initialized** with versions prior to V4.10.0.\n\nThe application uses the weak pseudo-random number generator `math/rand` seeded with `time.Now().UnixNano()` to generate critical security secrets, including the `secret_key`, and `hash_id_salt`. These secrets are generated upon first startup and persisted in the database.\n\nAn attacker can exploit this by obtaining the administrator\u0027s account creation time (via public API endpoints) to narrow the search window for the PRNG seed, and use known hashid to validate the seed. By brute-forcing the seed (demonstrated to take \u003c3 hours on general consumer PC), an attacker can predict the `secret_key`. This allows them to forge valid JSON Web Tokens (JWTs) for any user, including administrators, leading to full account takeover and privilege escalation.\n\n**Note**: Servers running V4.10.0+ are still vulnerable if they were originally installed using an older version, as the weak secrets persist in the configuration.\n\n### Patches\nThe issue has been addressed in version 4.13.0.\nThis patch introduces a migration mechanism that automatically:\n\n1. Invalidate the existing `secret_key`.\n2. Regenerate a new, cryptographically secure `secret_key` using crypto/rand.\n\nUsers should upgrade to 4.13.0 immediately.\n\n### Workarounds\nIf an immediate upgrade is not possible, administrators must manually rotate the critical secrets in the configuration file to invalidate potential exploits:\n\n1. Stop the Cloudreve service.\n2. In Cloudreve database, locate `secret_key` setting.\n3. Replace the value with a long, random string (e.g., generated via `openssl rand -base64 64`).\n4. Restart the Cloudreve service.\n\n_Note: This will log out all currently active users._\n\n### Resources\n* Vulnerable Code (Seeding): https://github.com/cloudreve/cloudreve/blob/87d48ac4a7acbc68064c2b9cb23793ac97f4392d/pkg/util/common.go#L21C1-L23C2\n* Vulnerable Code (Usage): https://github.com/cloudreve/cloudreve/blob/87d48ac4a7acbc68064c2b9cb23793ac97f4392d/inventory/setting.go#L591\n* [Go Documentation (math/rand)](https://pkg.go.dev/math/rand)",
