Release notes

Sourced from tracing-subscriber's releases.

tracing-subscriber 0.3.20

Security Fix: ANSI Escape Sequence Injection (CVE-TBD)

Impact

Previous versions of tracing-subscriber were vulnerable to ANSI escape sequence injection attacks. Untrusted user input containing ANSI escape sequences could be injected into terminal output when logged, potentially allowing attackers to:

• Manipulate terminal title bars
• Clear screens or modify terminal display
• Potentially mislead users through terminal manipulation

In isolation, impact is minimal, however security issues have been found in terminal emulators that enabled an attacker to use ANSI escape sequences via logs to exploit vulnerabilities in the terminal emulator.

Solution

Version 0.3.20 fixes this vulnerability by escaping ANSI control characters in when writing events to destinations that may be printed to the terminal.

Affected Versions

All versions of tracing-subscriber prior to 0.3.20 are affected by this vulnerability.

Recommendations

Immediate Action Required: We recommend upgrading to tracing-subscriber 0.3.20 immediately, especially if your application:

• Logs user-provided input (form data, HTTP headers, query parameters, etc.)
• Runs in environments where terminal output is displayed to users

Migration

This is a patch release with no breaking API changes. Simply update your Cargo.toml:

[dependencies]
tracing-subscriber = "0.3.20"
