Package	Type	Update	Change

GitHub Vulnerability Alerts

CVE-2025-58160

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.

Patches

tracing-subscriber 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.

Workarounds

Avoid printing logs to terminal emulators without escaping ANSI control sequences.

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
