- 8.5HighAug 13, 2026S9y Serendipity SSRFCVE-2026-73629Serendipity 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.
- 6.1MediumAug 13, 2026S9y Serendipity XSSCVE-2026-73628Serendipity 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.
- 7.2HighApr 15, 2026S9y serendipityCVE-2026-39971Serendipity 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 SM
- 6.9MediumApr 15, 2026S9y serendipityCVE-2026-39963Serendipity 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 do
- 8.8HighDec 17, 2025S9y serendipity Path traversal / file handlingCVE-2023-53933Serendipity 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.1% likely
- 5.4MediumDec 17, 2025S9y serendipity XSSCVE-2023-53932Serendipity 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.
- 7.2HighDec 10, 2025S9y serendipity Path traversal / file handlingCVE-2024-58282Serendipity 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.1% likely
