Unknown vulnerability in the mail command handler in Mailman before 2.0.14 allows remote attackers to cause a denial of service (crash) via malformed e-mail commands.CVE-2003-0038gnumailman+1EPSS score4.76%
Cross-site scripting (XSS) vulnerability in options.py for Mailman 2.1 allows remote attackers to inject script or HTML into web pages via the (1) email or (2) language parameters.CVE-2003-0992gnumailmanEPSS score1.26%
Cross-site scripting (XSS) vulnerability in the create CGI script for Mailman before 2.1.3 allows remote attackers to steal cookies of other users.CVE-2003-0965gnumailmanEPSS score2.00%
Cross-site scripting (XSS) vulnerability in the admin CGI script for Mailman before 2.1.4 allows remote attackers to steal session cookies and conduct unauthorized activities.CVE-2021-42096ubuntumailman+2EPSS score1.25%
GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A certain csrf_token value is derived from the admin password, and may be useful in conducting a brute-force attack against that password.CVE-2021-42097ubuntumailman+2EPSS score1.33%
GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin (e.g., for account takeover).CVE-2021-43331ubuntumailman+2EPSS score1.38%
In GNU Mailman before 2.1.36, a crafted URL to the Cgi/options.py user options page can execute arbitrary JavaScript for XSS.CVE-2021-43332ubuntumailman+2EPSS score1.15%
In GNU Mailman before 2.1.36, the CSRF token for the Cgi/admindb.py admindb page contains an encrypted version of the list admin password. This could potentially be cracked by a moderator via an offline brute-force attack.CVE-2021-44227ubuntumailman+6EPSS score0.76%
In GNU Mailman before 2.1.38, a list member or moderator can get a CSRF token and craft an admin request (using that token) to set a new admin password or make other changes.CVE-2021-34337debianmailman3+5EPSS score0.30%
An issue was discovered in Mailman Core before 3.3.5. An attacker with access to the REST API could use timing attacks to determine the value of the configured REST API password and then make arbitrary REST API calls. The REST API is bound to localhost by default, limiting the ability for attackers to exploit this, but can optionally be made to listen on other interfaces.CVE-2015-2775canonicalubuntu_linux+8EPSS score7.91%
Directory traversal vulnerability in GNU Mailman before 2.1.20, when not using a static alias, allows remote attackers to execute arbitrary files via a .. (dot dot) in a list name.CVE-2016-7123ubuntumailman+1EPSS score1.53%
Cross-site request forgery (CSRF) vulnerability in the admin web interface in GNU Mailman before 2.1.15 allows remote attackers to hijack the authentication of administrators.CVE-2016-6893debianmailman+7EPSS score1.61%
Cross-site request forgery (CSRF) vulnerability in the user options page in GNU Mailman 2.1.x before 2.1.23 allows remote attackers to hijack the authentication of arbitrary users for requests that modify an option, as demonstrated by gaining access to the credentials of a victim's account.CVE-2025-43920ubuntumailman+1EPSS score0.59%
GNU Mailman 2.1.39, as bundled in cPanel (and WHM), in certain external archiver configurations, allows unauthenticated attackers to execute arbitrary OS commands via shell metacharacters in an email Subject line. NOTE: multiple third parties report that they are unable to reproduce this, regardless of whether cPanel or WHM is used.CVE-2025-43919ubuntumailman+1EPSS score1.38%
GNU Mailman 2.1.39, as bundled in cPanel (and WHM), allows unauthenticated attackers to read arbitrary files via ../ directory traversal at /mailman/private/mailman (aka the private archive authentication endpoint) via the username parameter. NOTE: multiple third parties report that they are unable to reproduce this, regardless of whether cPanel or WHM is used.CVE-2025-43921ubuntumailman+1EPSS score0.45%
GNU Mailman 2.1.39, as bundled in cPanel (and WHM), allows unauthenticated attackers to create lists via the /mailman/create endpoint. NOTE: multiple third parties report that they are unable to reproduce this, regardless of whether cPanel or WHM is used.CVE-2020-15011canonicalubuntu_linux+23EPSS score1.89%
