- 5.3MediumOct 23, 2026cactiCVE-2026-49442Cacti is an open source performance and fault management framework. Prior to version 1.2.31, a User Enumeration vulnerability allows an attacker to identify valid usernames on the Cacti service. When a user attempts to log in, the application returns slightly different error messages depending on whether the provided username exists in the system. When username exists on Cacti, in the response, they see Access Denied! Login failed. When it does not exist on Cacti, they see Access Denied! Login F
- 5.5MediumOct 23, 2026cacti SQL injectionCVE-2026-46531Cacti is an open source performance and fault management framework. From version 1.2.27 to before version 1.2.31, Cacti contains an authenticated stored second-order SQL injection in the automation tree rule item handler. A user holding the Automation realm (default General Administration role) can persist an arbitrary SQL fragment in the automation_tree_rule_items.field column. The fragment is later concatenated directly into a SELECT ... AS source FROM ... clause in lib/api_automation.php :: c
- 7.2HighOct 23, 2026cacti Code / command injectionCVE-2026-39902Cacti is an open source performance and fault management framework. Prior to version 1.2.31, the prior blocklist ([;&| `$\\n\r]) omitted single-quote, double-quote, redirect operators, subshell parens and braces. An authenticated admin could save an input_string` containing single-quote, redirect operator, or subshell parens, and pass the check. This issue has been patched in version 1.2.31.Exploit code
- 6.5MediumJun 25, 2026cacti Crypto / certificateCVE-2026-40941Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have a package import signature validation bypass allows which allows self-signed packages. This issue has been fixed in version 1.2.31.
- 6.5MediumJun 25, 2026cacti Path traversal / file handlingCVE-2026-40084Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Path Traversal through the Report format_file Parameter, causing arbitrary file read. This vulnerability occurs in two stages. In the first stage (stored injection), lib/html_reports.php at line 283 stores $save['format_file'] = $post['format_file'] directly into the database without any validation. In the second stage (file read), lib/reports.php at line 667 concatenates CACTI_PATH
- 7.2HighJun 25, 2026cacti SQL injectionCVE-2026-40083Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have SQL Injection through unsanitized unserialize+implode in managers.php. At line 756 of managers.php, the application assigns $selected_items by calling cacti_unserialize(stripslashes(gnrv('selected_graphs_array'))). The cacti_unserialize() function calls unserialize() with allowed_classes set to false, which prevents object injection but still allows arbitrary string arrays to be deserialized. Th
- 5.4MediumJun 25, 2026cactiCVE-2026-40082Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have missing session_regenerate_id() after login, leading to Session Fixation. session_regenerate_id() is NOT called after successful login. The login flow at auth_login.php:203-207 directly sets $_SESSION[SESS_USER_ID] without rotating the session ID. The session cookie configuration is otherwise good (httponly=true, samesite=Strict, secure=true for HTTPS at include/global.php:513-537), but these do no
- 6.1MediumJun 25, 2026cactiCVE-2026-40080Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Open Redirect through a substring check rather than a host check at str_contains($referer, CACTI_PATH_URL). When the user's login_opts == '1' (redirect to referer after login), the function used $_SERVER['HTTP_REFERER'] directly. An attacker could craft a referer such as https://evil.com/cacti/. Where CACTI_PATH_URL is /cacti/, the substring matches and the user is redirected to evil.
- 9.8CriticalJun 25, 2026cacti Code / command injectionCVE-2026-40079Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Command Injection due to lack of sanitization in the escape_command() function. The escape_command() function at lib/rrd.php is a no-op: it returns $command unchanged. The command line built by rrdtool_function_graph() is passed through this function and then to shell_exec($full_commandline). The risk is in __rrd_execute() where text_format values from graph templates (which may contai
- 7.6HighJun 25, 2026cacti SQL injectionCVE-2026-39951Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have a Stored SQL Injection vulnerability through graph_name_regexp in the Reports feature. This issue has been fixed in version 1.2.31.
- 9.8CriticalJun 24, 2026cacti SQL injectionCVE-2026-39955Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have pre-authentication SQL Injection via unanchored FILTER_VALIDATE_REGEXP in graph_view.php. This issue has been fixed in version 1.2.31.
- 9.8CriticalJun 24, 2026cacti SQL injectionCVE-2026-39948Cacti is an open source performance and fault management framework. In versions 1.2.30 and prior, the rfilter request parameter is retrieved via the raw accessor grv() (rather than gfrv() with FILTER_VALIDATE_IS_REGEX validation) and concatenated directly into RLIKE SQL clauses in lib/html_graph.php and lib/html_tree.php, which are reachable pre-authentication through graph_view.php on installations with guest graph viewing enabled. Because the unbalanced-quote payload bypasses the regex validat
- 9.8CriticalJun 24, 2026cacti Path traversal / file handlingCVE-2026-39938Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have unauthenticated LFI through graph_theme and rrdtool IPC serialization hardening. This issue has been resolved in version 1.2.31.
- 6.1MediumJun 24, 2026cacti XSSCVE-2026-39900Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Reflected XSS via tab parameter in the auth_profile.php JavaScript context. This issue has been fixed in version 1.2.31.

- 6.1MediumJun 24, 2026cacti XSSCVE-2026-39897Cacti is an open source performance and fault management framework. Versions 1.2.30 and below contain a Reflected XSS vulnerability in the html_auth_footer. This issue has been fixed in version 1.2.31.
- 2.9LowJun 24, 2026cactiCVE-2026-39894Cacti is an open source performance and fault management framework. In versions 1.2.30 and below, the locale-dependent decimal formatting in rrdtool_function_update() can corrupt RRDtool metric values. The rrdtool_function_update() function checks metric values with is_numeric() and concatenates them into the RRDtool update command via PHP string interpolation. PHP's string cast of floats is locale-sensitive: if LC_NUMERIC uses comma as decimal separator (e.g., de_DE), a value of 1.5 becomes "1,
- 9.8CriticalJun 24, 2026cacti SQL injectionCVE-2026-39893Cacti is an open source performance and fault management framework. In versions 1.2.30 and prior, the rfilter request variable was concatenated into a RLIKE SQL clause without sanitization. The endpoint does not require authentication (graph viewing supports guest access via the configured guest user), so the SQLi was reachable pre-auth on installs with guest viewing enabled. This issue was fixed in version 1.2.31.
