| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2025-52968 | xdg-open in xdg-utils through 1.2.1 can send requests containing SameSite=Strict cookies, which can facilitate CSRF. (For example, xdg-open could be modified to, by default, associate x-scheme-handler/https with the execution of a browser with command-line options that arrange for an empty cookie store, although this would add substantial complexity, and would not be considered a desirable or expected behavior by all users.) NOTE: this is disputed because integrations of xdg-open typically do no | [email protected] | 2.7 | 0.18% | 2025-06-23 | 2026-06-17 |
| CVE-2022-4055 | When xdg-mail is configured to use thunderbird for mailto URLs, improper parsing of the URL can lead to additional headers being passed to thunderbird that should not be included per RFC 2368. An attacker can use this method to create a mailto URL that looks safe to users, but will actually attach files when clicked. | [email protected] | 7.4 | 0.65% | 2022-11-18 | 2026-06-17 |
| CVE-2015-1877 | The open_generic_xdg_mime function in xdg-open in xdg-utils 1.1.0 rc1 in Debian, when using dash, does not properly handle local variables, which allows remote attackers to execute arbitrary commands via a crafted file. | [email protected] | 8.8 | 3.21% | 2021-06-02 | 2026-06-16 |
| CVE-2020-27748 | A flaw was found in the xdg-email component of xdg-utils-1.1.0-rc1 and newer. When handling mailto: URIs, xdg-email allows attachments to be discreetly added via the URI when being passed to Thunderbird. An attacker could potentially send a victim a URI that automatically attaches a sensitive file to a new email. If a victim user does not notice that an attachment was added and sends the email, this could result in sensitive information disclosure. It has been confirmed that the code behind this | [email protected] | 6.5 | 1.44% | 2021-06-01 | 2026-06-16 |
| CVE-2017-18266 | The open_envvar function in xdg-open in xdg-utils before 1.1.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL, as demonstrated by %s in this environment variable. | [email protected] | 8.8 | 2.47% | 2018-05-10 | 2026-06-16 |
| CVE-2009-0068 | Interaction error in xdg-open allows remote attackers to execute arbitrary code by sending a file with a dangerous MIME type but using a safe type that Firefox sends to xdg-open, which causes xdg-open to process the dangerous file type through automatic type detection, as demonstrated by overwriting the .desktop file. | [email protected] | 6.8 | 2.16% | 2009-01-07 | 2026-06-16 |
