0.3.19→0.3.20Tracing logging user input may result in poisoning logs with ANSI escape sequences
CVE-2025-58160 / GHSA-xwfj-jgwm-7wp5 / RUSTSEC-2025-0055
More information
Details
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:
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-subscriberversion 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.
