A flaw, similar to to CVE-2016-9646, exists in ikiwiki before 3.20170111, in the passwordauth plugin's use of CGI::FormBuilder, allowing an attacker to bypass authentication via repeated parameters.
ikiwiki before 3.20170111.1 and 3.2018x and 3.2019x before 3.20190228 allows SSRF via the aggregate plugin. The impact also includes reading local files via file: URIs.
Plugin/passwordauth.pm (aka the passwordauth plugin) in ikiwiki 1.34 through 2.47 allows remote attackers to bypass authentication, and login to any account for which an OpenID identity is configured and a password is not configured, by specifying an empty password during the login sequence.
Cross-site scripting (XSS) vulnerability in the cgierror function in CGI.pm in ikiwiki before 3.20160506 might allow remote attackers to inject arbitrary web script or HTML via unspecified vectors involving an error message.
Cross-site scripting (XSS) vulnerability in templates/openid-selector.tmpl in ikiwiki before 3.20150329 allows remote attackers to inject arbitrary web script or HTML via the openididentifier parameter in a verify action to ikiwiki.cgi.
Incomplete blacklist vulnerability in the teximg plugin in ikiwiki before 3.1415926 and 2.x before 2.53.4 allows context-dependent attackers to read arbitrary files via crafted TeX commands.
Multiple cross-site scripting (XSS) vulnerabilities in the meta plugin (Plugin/meta.pm) in ikiwiki before 3.20120516 allow remote attackers to inject arbitrary web script or HTML via the (1) author or (2) authorurl meta tags.
Cross-site scripting (XSS) vulnerability in the meta plugin in Ikiwiki before 1.1.47 allows remote attackers to inject arbitrary web script or HTML via meta tags.
Cross-site scripting (XSS) vulnerability in the htmlscrubber in Ikiwiki before 1.1.46 allows remote attackers to inject arbitrary web script or HTML via title contents.
Cross-site request forgery (CSRF) vulnerability in Ikiwiki before 2.42 allows remote attackers to modify user preferences, including passwords, via the (1) preferences and (2) edit forms.
ikiwiki before 3.20110328 does not ascertain whether the htmlscrubber plugin is enabled during processing of the "meta stylesheet" directive, which allows remote authenticated users to conduct cross-site scripting (XSS) attacks via crafted Cascading Style Sheets (CSS) token sequences in (1) the default stylesheet or (2) an alternate stylesheet.
