There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Guzzle is an extensible PHP HTTP client. Prior to 7.12.1, CookieJar incorrectly accepts cookies with a
    dot-only Domain attribute and whitespace-padded variants. SetCookie::matchesDomain() removes leading dots
    from the cookie domain, normalizing dot-only values to the empty string; SetCookie::validate() only
    rejected a strictly empty domain, so these cookies could be stored and the empty normalized domain was
    treated as matching any request host. An attacker-controlled origin that an application requests with a
    shared cookie jar can therefore set a cookie that Guzzle later sends to unrelated hosts using the same
    jar. This may allow cookie injection or session fixation against downstream services, depending on how
    those services interpret the injected cookie. This vulnerability is fixed in 7.12.1. (CVE-2026-55767)

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