CVSS v3.1 |
| Serendipity before 2.6.0 contains a server-side request forgery vulnerability in the serendipity_url_allowed() filter that fails to block hex-encoded IPv4 addresses, IPv6 literals, and link-local ranges. Authenticated users with adminImagesAdd permission can bypass the filter using alternate address formats to request internal services and retrieve response bodies through the public uploads directory. |
| Serendipity versions >= 2.3.5 and <= 2.6.0 contain a reflected cross-site scripting vulnerability in the search clean-URL route (/search/<term>). In include/functions_routing.inc.php serveSearch(), the sanitisation pipeline runs urldecode() after HTML-encoding, so a single URL-encoded HTML payload survives strip_tags() and htmlspecialchars() and is then decoded back into live HTML in the page. A crafted search link can execute arbitrary JavaScript in the victim's browser. Fixed in 2.6.1. |
| Serendipity before 2.6.1 contains an open redirect vulnerability in exit.php that allows unauthenticated attackers to redirect users to arbitrary external sites by supplying a malicious Base64-encoded url parameter when the Track Exits plugin is configured with commentredirection set to s9y. Attackers can craft trusted-looking URLs leveraging the legitimate blog domain to conduct phishing, deliver malware, or bypass URL reputation filters. |
| Serendipity before 2.6.1 contains an authentication context confusion vulnerability where password validation and session loading operate independently without ensuring both use the same user record. An authenticated Editor can create a username collision with an Administrator account and obtain administrative privileges by logging in with their own password while the session loads the Administrator's account data. |
| Serendipity is a PHP-powered weblog engine. In versions 2.6-beta2 and below, the email sending functionality in include/functions.inc.php inserts $_SERVER['HTTP_HOST'] directly into the Message-ID SMTP header without validation, and the existing sanitization function serendipity_isResponseClean() is not called on HTTP_HOST before embedding it. An attacker who can control the Host header during an email-triggering action such as comment notifications or subscription emails can inject arbitrary SMTP headers into outgoing emails. This enables identity spoofing, reply hijacking via manipulated Message-ID threading, and email reputation abuse through the attacker's domain being embedded in legitimate mail headers. This issue has been fixed in version 2.6.0. |
| Serendipity is a PHP-powered weblog engine. In versions 2.6-beta2 and below, the serendipity_setCookie() function in include/functions_config.inc.php uses $_SERVER['HTTP_HOST'] without validation as the domain parameter of setcookie(). An attacker who can influence the Host header at login time, such as via MITM, reverse proxy misconfiguration, or load balancer manipulation, can force authentication cookies including session tokens and auto-login tokens to be scoped to an attacker-controlled domain. This enables session fixation, token leakage to attacker-controlled infrastructure, and privilege escalation if an admin logs in under a poisoned Host header. This issue has been fixed in version 2.6.0. |
| Multiple directory traversal vulnerabilities in Serendipity 1.0.3 and earlier allow remote attackers to read or include arbitrary local files via a .. (dot dot) sequence in the serendipity[charset] parameter in (1) include/lang.inc.php; or to plugins/ scripts (2) serendipity_event_bbcode/serendipity_event_bbcode.php, (3) serendipity_event_browsercompatibility/serendipity_event_browsercompatibility.php, (4) serendipity_event_contentrewrite/serendipity_event_contentrewrite.php, (5) serendipity_event_creativecommons/serendipity_event_creativecommons.php, (6) serendipity_event_emoticate/serendipity_event_emoticate.php, (7) serendipity_event_entryproperties/serendipity_event_entryproperties.php, (8) serendipity_event_karma/serendipity_event_karma.php, (9) serendipity_event_livesearch/serendipity_event_livesearch.php, (10) serendipity_event_mailer/serendipity_event_mailer.php, (11) serendipity_event_nl2br/serendipity_event_nl2br.php, (12) serendipity_event_s9ymarkup/serendipity_event_s9ymarkup.php, (13) serendipity_event_searchhighlight/serendipity_event_searchhighlight.php, (14) serendipity_event_spamblock/serendipity_event_spamblock.php, (15) serendipity_event_spartacus/serendipity_event_spartacus.php, (16) serendipity_event_statistics/serendipity_plugin_statistics.php, (17) serendipity_event_templatechooser/serendipity_event_templatechooser.php, (18) serendipity_event_textile/serendipity_event_textile.php, (19) serendipity_event_textwiki/serendipity_event_textwiki.php, (20) serendipity_event_trackexits/serendipity_event_trackexits.php, (21) serendipity_event_weblogping/serendipity_event_weblogping.php, (22) serendipity_event_xhtmlcleanup/serendipity_event_xhtmlcleanup.php, (23) serendipity_plugin_comments/serendipity_plugin_comments.php, (24) serendipity_plugin_creativecommons/serendipity_plugin_creativecommons.php, (25) serendipity_plugin_entrylinks/serendipity_plugin_entrylinks.php, (26) serendipity_plugin_eventwrapper/serendipity_plugin_eventwrapper.php, (27) serendipity_plugin_history/serendipity_plugin_history.php, (28) serendipity_plugin_recententries/serendipity_plugin_recententries.php, (29) serendipity_plugin_remoterss/serendipity_plugin_remoterss.php, (30) serendipity_plugin_shoutbox/serendipity_plugin_shoutbox.php, and and (31) serendipity_plugin_templatedropdown/serendipity_plugin_templatedropdown.php. |
| config.php in S9Y Serendipity 1.0 beta 2 allows remote attackers to inject arbitrary PHP code by editing values that are stored in config.php and later executed. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information. |
| Serendipity 2.5.0 contains a remote code execution vulnerability that allows authenticated administrators to upload malicious PHP files through the media upload functionality. Attackers can exploit the file upload mechanism by creating a PHP shell with a command execution form that enables arbitrary system command execution on the web server. |
| Serendipity 2.4.0 contains a remote code execution vulnerability that allows authenticated attackers to upload malicious PHP files with .phar extension. Attackers can upload files with system command payloads to the media upload endpoint and execute arbitrary commands on the server. |
| Serendipity 2.4.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject malicious scripts through blog entry creation. Attackers can craft entries with JavaScript payloads that will execute when other users view the compromised blog post. |
| Stored XSS in Serendipity v2.1-rc1 allows an attacker to steal an admin's cookie and other information by composing a new entry as an editor user. This is related to lack of the serendipity_event_xsstrust plugin and a set_config error in that plugin. |
| Serendipity 2.0.3 is vulnerable to a SQL injection in the blog component resulting in information disclosure |
| SQL injection vulnerability in include/functions_entries.inc.php in Serendipity 2.0.5 allows remote authenticated users to execute arbitrary SQL commands via the cat parameter. |
| Serendipity through 2.0.5 allows CSRF for the installation of an event plugin or a sidebar plugin. |
| Open redirect vulnerability in comment.php in Serendipity through 2.0.5 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the HTTP Referer header. |
| comment.php in Serendipity through 2.0.5 allows CSRF in deleting any comments. |
| There is CSRF in Serendipity 2.0.5, allowing attackers to install any themes via a GET request. |
| Multiple incomplete blacklist vulnerabilities in the serendipity_isActiveFile function in include/functions_images.inc.php in Serendipity before 2.0.2 allow remote authenticated users to execute arbitrary PHP code by uploading a file with a (1) .pht or (2) .phtml extension. |
| SQL injection vulnerability in the serendipity_checkCommentToken function in include/functions_comments.inc.php in Serendipity before 2.0.2, when "Use Tokens for Comment Moderation" is enabled, allows remote administrators to execute arbitrary SQL commands via the serendipity[id] parameter to serendipity_admin.php. |
