Multiple cross-site scripting (XSS) vulnerabilities in phpPgAdmin before 5.0.3 allow remote attackers to inject arbitrary web script or HTML via (1) a web page title, related to classes/Misc.php; or the (2) return_url or (3) return_desc parameter to display.php.
Directory traversal vulnerability in libraries/lib.inc.php in phpPgAdmin 4.2.1 and earlier, when register_globals is enabled, allows remote attackers to read arbitrary files via a .. (dot dot) in the _language parameter to index.php.
Encoded directory traversal vulnerability in phpPgAdmin 3.1 to 3.5.3 allows remote attackers to access arbitrary files via "%2e%2e%2f" (encoded dot dot) sequences in the formLanguage parameter.
