CVE-2026-85733 (GCVE-0-2026-85733)
Vulnerability from cvelistv5

CWE
  • CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor
Summary
FrankenPHP is a modern application server for PHP. Prior to 1.12.5, the official FrankenPHP Debian and Alpine Docker images include a default /app/public/index.php that executes phpinfo(). A derived image that does not overwrite this placeholder serves the diagnostics page in production and can disclose environment variables used for secrets, PHP configuration directives, loaded extensions, software versions, and system paths. Images built using the documented pattern with their own /app/public/index.php are not affected, and already derived images must be rebuilt or supplied with an application index to remove the exposed placeholder. This issue is fixed in version 1.12.5.

CVE-2026-82416 (GCVE-0-2026-82416)
Vulnerability from cvelistv5
Published

Modified
2026-10-13 20:22
CWE
  • CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
  • CWE-488 - Exposure of Data Element to Wrong Session
Summary
FrankenPHP is a modern application server for PHP. Prior to 1.12.5, FrankenPHP worker mode can retain PHP session state between requests when the session extension is loaded as a shared module and is unavailable through HAVE_PHP_SESSION at compile time. In this build configuration, frankenphp_reset_session_state() is compiled out, PS(id) can survive a request boundary, and a subsequent session_start() can ignore the new request's cookie because an identifier is already present. Under concurrent requests, session_id() can therefore return another client's identifier or a stale identifier from a previous request on the same worker thread, causing cross-user session exposure, possible session hijacking, and intermittent logout behavior. Builds with the session extension statically linked, including the official static binaries and Docker images, are not affected. This issue is fixed in version 1.12.5.

CVE-2026-45062 (GCVE-0-2026-45062)
Vulnerability from cvelistv5
Published
2026-06-10 17:38
Modified
2026-06-11 14:00
CWE
  • CWE-20 - Improper Input Validation
  • CWE-176 - Improper Handling of Unicode Encoding
  • CWE-178 - Improper Handling of Case Sensitivity
Summary
FrankenPHP is a modern application server for PHP. From version 1.11.2 to before version 1.12.3, the splitPos() function in cgi.go misuses golang.org/x/text/search with search.IgnoreCase when the request path contains a non-ASCII byte. Two distinct flaws in that fallback let an attacker mislead FrankenPHP into treating a non-.php file as a .php script. In any deployment where the attacker can place content into a file served by FrankenPHP (uploads, file storage, etc.), this can be escalated to remote code execution by crafting a URL whose path triggers either flaw. This issue has been patched in version 1.12.3.

CVE-2026-24895 (GCVE-0-2026-24895)
Vulnerability from cvelistv5
Published
2026-02-12 19:16
Modified
2026-02-12 20:04
CWE
  • CWE-180 - Incorrect Behavior Order: Validate Before Canonicalize
Summary
FrankenPHP is a modern application server for PHP. Prior to 1.11.2, FrankenPHP’s CGI path splitting logic improperly handles Unicode characters during case conversion. The logic computes the split index (for finding .php) on a lowercased copy of the request path but applies that byte index to the original path. Because strings.ToLower() in Go can increase the byte length of certain UTF-8 characters (e.g., Ⱥ expands when lowercased), the computed index may not align with the correct position in the original string. This results in an incorrect SCRIPT_NAME and SCRIPT_FILENAME, potentially causing FrankenPHP to execute a file other than the one intended by the URI. This vulnerability is fixed in 1.11.2.

Vulnerability from cvelistv5

CWE
  • CWE-269 - Improper Privilege Management
  • CWE-384 - Session Fixation
  • CWE-613 - Insufficient Session Expiration
Summary
FrankenPHP is a modern application server for PHP. Prior to 1.11.2, when running FrankenPHP in worker mode, the $_SESSION superglobal is not correctly reset between requests. This allows a subsequent request processed by the same worker to access the $_SESSION data of the previous request (potentially belonging to a different user) before session_start() is called. This vulnerability is fixed in 1.11.2.
