The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-0b03072979 advisory.

    ### Version 2.9.3 -  2025-12-30

      * Security: Fixed ANSI sequence injection (GHSA-59pp-r3rg-353g / CVE-2025-67746)
      * Fixed `COMPOSER_NO_SECURITY_BLOCKING` env var not being respected for `updates` done via the `install`     command, and added `--no-security-blocking` flag to `install` as well (#12677)
      * Fixed `update --lock` / `update mirrors` not working when locked packages contain vulnerabilities     (#12645)
      * Fixed `client-certificate` authentication implementation (#12667)
      * Fixed `php-ext` schema not being validated in ValidatingArrayLoader (#12694)
      * Fixed crash when `--bump-after-update` is used and the lock file is disabled (#12660)
      * Fixed support for SecureTransport + LibreSSL on macOS (#12615)
      * Fixed display of reasons for why advisories are ignored (#12668)
      * Fixed compatibility issues when git has log.showSignature enabled (#12666)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Composer is a dependency manager for PHP. In versions on the 2.x branch prior to 2.2.26 and 2.9.3,     attackers controlling remote sources that Composer downloads from might in some way inject ANSI control     characters in the terminal output of various Composer commands, causing mangled output and potentially     leading to confusion or DoS of the terminal application. There is no proven exploit and this has thus a     low severity but we still publish a CVE as it has potential for abuse, and we want to be on the safe side     informing users that they should upgrade. Versions 2.2.26 and 2.9.3 contain a patch for the issue.
    (CVE-2025-67746)

Note that Nessus relies on the presence of the package as reported by the vendor.
