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"

[EliahKagan]

This fixes a security vulnerability, CVE-2025-58160, with unsanitized ANSI escape sequences in a dependency. (This has some conceptual overlap with, but is separate from, CVE-2024-43785 in gitoxide-core, which of course this PR does not fix.)

Although not dire, I think this PR, as with most Dependabot security updates, is worth merging ahead of the grouped version updates, rather than waiting, even though in this case the wait would probably be only a few days.

The CI failure seems to be the same as on the main branch, which it looks like there's already a fix in progress in #2143, though I haven't looked into the breakage.

I expect this PR not to break anything, since it's a patch release bump, and also because the corresponding test PR in my fork, EliahKagan#88 -- where the base branch has not yet been fast-forwarded to include the commits that induced the current CI failure on main -- passes CI.

Another YOLO merge just one day after the previous one that broke CI on main. But the fix is already merged there, and I didn't think it was necessary to wait for CI here knowing that this patch update won't break anything.

If it does, I will take care.
