Token leakage refers to the unintentional or unauthorized exposure of sensitive authentication tokens. These tokens are typically used to grant access to specific resources or services without requiring the user to re-authenticate repeatedly. Examples include session tokens, API keys, and OAuth tokens.

When a token is leaked, it can fall into the hands of unauthorized individuals or malicious actors. This can lead to a severe security breach, as the attacker can then impersonate the legitimate user and gain access to their accounts or data. The consequences can range from data theft and financial fraud to unauthorized modifications of systems and services.

Token leakage can occur through various means. Insecure storage of tokens on client-side applications, accidental logging of tokens in public repositories, or transmission over unencrypted channels are common vulnerabilities. Phishing attacks can also trick users into revealing their tokens.

Preventing token leakage involves implementing robust security practices. This includes securely storing tokens using encryption, limiting token expiration times, avoiding logging sensitive tokens, and using secure communication protocols like HTTPS. Regular security audits and code reviews can help identify and mitigate potential leakage points. When a token is suspected of being leaked, immediate revocation and re-issuance are crucial steps to contain the damage.
