== Changelog ==

= 5.269 =
* 2026-02-19
* NEW: Added compatibility with temporary login plugins ("Temporary Login Without Password", "One Time Login", "Magic Login", "Login Links"). Temporary login links are now automatically whitelisted from suspicious query detection when the corresponding plugin is active. Detection is logged for audit purposes. Other plugins can extend this compatibility using the `securityninja_temporary_login_params` and `securityninja_is_temporary_login_link` filters - more info on website.
* FIX: Fixed fatal error "Object of class WP_Error could not be converted to string" in Overview tab when displaying event details containing WP_Error objects. The code now properly checks for WP_Error objects before passing them to esc_html() and displays the error message instead.
* FIX: Fixed fatal error preventing WooCommerce logins via public forms when SN_Geolocation class was not loaded. Code now checks for class existence before use.


= 5.268 =
* 2026-02-18
* FIX: Firewall now allows logged-in administrators to access WordPress backend (wp-admin, admin-ajax.php) even when their IP address is banned. This prevents administrators from being locked out when their IP was banned by a false positive from the suspicious query filter, 404 Guard, brute-force protection, or other firewall features. This fixes the "Updating failed. The response is not a valid JSON response" error when saving pages in the block editor (Gutenberg) when the admin's IP was previously banned.
* IMPROVED: UI label for suspicious query filtering has been updated from "Block Suspicious Page Requests" to "Filter Suspicious Queries" to match support documentation and make it easier for users to find the setting when following support instructions.
* FIX: 2FA login redirects now work correctly for users logging in via public forms (such as Paid Member Subscriptions, WooCommerce, and other third-party login forms). 

= 5.267 =
* 2026-02-13
* IMPROVED: Litespeed servers - Added documentation and in-app notices for all security headers (CSP, X-Frame-Options, X-Content-Type-Options, Strict-Transport-Security, Referrer-Policy, Permissions-Policy). LiteSpeed users can add headers directly to .htaccess using the examples in each test description. Thank you Tom for the feedback.
* FIX: Events Logger, Overview, and Visitor Log – Country flags now correctly show the event/visitor IP's country instead of the logged-in admin's IP when the site is behind Cloudflare or similar proxies.
* Improved: Core Scanner - Interface loads faster with tabs lazy-loading content in different tabs.
* IMPROVED: Firewall – When "Block IP Network" is enabled, known social and link-preview crawlers (e.g. Facebook, LinkedIn, Twitter) are no longer blocked by default. Link previews when you share your site on social networks now work without having to whitelist IPs.

= 5.266 =
* 2026-02-10
* Improvement: Logging details for 404 Guard.
* FIX: Login Protection – Banned IPs expired entries are removed immediately instead of waiting for the prune job.
* IMPROVED: Login Protection – Prune job for banned IPs now runs hourly.
* FIX: Cloud Firewall IP Management – "Locally Banned IPs" list now shows only currently banned IPs (expired bans are excluded).
* FIX: Cloud Firewall – Test IP and "Clear list of banned IPs" functionality fixed.
* Updated language file for translations.

= 5.265 =
* 2026-02-09
* Tested up to WP 6.9.1
* FIX: Issues with 2FA for some user.
* IMPROVED: Vulnerability list updating faster and consume less memory.

= 5.264 =
* 2026-01-31
* FIX: Fixed wpdb::prepare() error during plugin uninstallation when dropping database tables.
* FIX: Vulnerability scanner no longer blocks wp-admin after deactivating and reactivating the plugin. If the vulnerability data files are missing or unreadable (e.g. after reactivation or server changes), the plugin now recovers automatically: it shows the vulnerability count as zero until the data is restored in the background, and the dashboard continues to load normally.
* IMPROVED: Vulnerability module now recreates and re-downloads its data files when they are missing, so you no longer need to reinstall the plugin to fix a "JSONL file not readable" error.
* FIX: Hardened vulnerability JSONL file handling: guard fclose() on stream and catch all errors when counting records, so missing or unreadable files never cause a fatal in wp-admin.
* FIX: Login Protection - "Failed login warnings" toggle now correctly saves when disabled (was reverting to enabled because unchecked checkbox is omitted from form POST).
* FIX: 2FA – Disabling 2FA in settings now persists correctly; toggle uses a hidden input so unchecked state is saved.

= 5.263 =
* 2026-01-25
* Improved bandwidth usage getting vulnerabilities for all users.
* Improved: Vulnerability scanner now reads vulnerability feeds in a streaming, memory-efficient way to reduce peak memory usage.

= 5.262 =
* 2026-01-20
* NEW: Free users now benefit from the firewall based on the excellent 8G Firewall by Jeff Star.
* NEW: Events logger now part of free version, basic event monitoring and logging for your site. More advanced tracking in premium version available.
* NEW: Core Scanner - Added ability to ignore specific files and patterns from scan results using the securityninja_core_scanner_ignore_files filter. Ignored files are displayed in a separate section for transparency. https://wpsecurityninja.com/docs/core-scanner/how-to-ignore-files/ - Thank you Gary.
* IMPROVED: Events Logger - All modules are now included in email reports by default. Users can deselect specific modules in settings.
* FIX: Events Logger - Prevented excessive memory usage by skipping translation hooks and reducing repeated license checks during audit logging.
* NEW: Quick firewall stats in the sidebar.
* Improved: Added 'php_errorlog' to the list of allowed files to view by the file viewer.
* Improved: Added firewall events to the overview page for free users.
* FIX: Fixed CIDR notation matching in IP whitelist - CIDR ranges now correctly match IPs within the range - Thank you Dirk.
* FIX: 2FA generation now uses your site's URL—rather than the site name—for labeling in authenticator apps, ensuring greater clarity and consistency.
* FIX: Refactor local request check in Wf_Sn_Tests class by introducing a dedicated method. Thank you Jean.
* Tested up to WP 6.9


= 5.261 =
* 2025-11-17
* Fixed: 2FA - Changed key name format from "site_url (username):email" to "site_url:username" -  Thank you Davina.
* Fixed: Compatibility warning with WordPress 6.7 regarding translation loading timing
* Fixed: Server security restriction warning when checking wp-config.php file location
* Fixed: Fixed critical bug where database prefix changer added an extra underscore when updating wp-config.php, causing WordPress to look for non-existent tables with double underscores (e.g., wp_12345__posts instead of wp_12345_posts). Thank you Tchai.
* Fixed: Database prefix changer to properly update option names and meta keys when changing from custom prefixes (not just "wp_").
* IMPROVED: Database prefix changer now works with any prefix, not just the default "wp_". Can now rename tables when changing from one custom prefix to another. All plugin tables are automatically included in the renaming process.

= 5.260 =
* 2025-11-12
* NEW: Failed login email warnings - administrators receive email notifications when someone attempts to log in with their username and fails. Can be enabled in Login Form Protection settings.
* NEW: Admin IPs are automatically whitelisted on plugin activation and successful admin login to prevent administrators from being blocked. Thank you Val.
* FIX: Fixed country blocking to respect "only block backend" setting when enabled. Thank you Guru for the tip.
* IMPROVED: Secret access URL processing has been moved up in the request cycle to make sure IP whitelisting happens before any ban checks, so blocked visitors should be able to get back on the site more reliably.
* IMPROVED: wp-config.php backups are stored in encrypted format (AES-256-CBC) to ensure data security. Each backup uses a unique encryption key and initialization vector. This was introduced in a previous release, but was not added to the changelog.
* Update 3rd party libraries - Freemius SDK 2.13.0 among others.

= 5.259 =
* 2025-11-07
* IMPROVED: Made the dashboard widget visible when white label mode is enabled. Previously the widget was hidden instead. Thank you for the suggestion, Dmitry.
* IMPROVED: Added count-based limit (5000 entries) to visitor log pruning to prevent database bloat on high-traffic sites.
* IMPROVED: Removed deprecated X-XSS-Protection header from REST API - modern browsers ignore this header and Content-Security-Policy is the recommended replacement. Thank you Dmitry for the suggestions.
* IMPROVED: More information on CSP in our knowledgebase. 
* FIX: Fixed typo in Permissions-Policy description (explitly → explicitly).
* FIX: Updated Permissions-Policy documentation link from Feature-Policy to Permissions-Policy URL.
* FIX: Corrected Nginx example in Content-Security-Policy test descriptions (was showing X-Frame-Options instead of CSP).
* Preparing for plugin rewrite -> improving the free version and streamlining the premium and free feature set.

= 5.258 =
* 2025-11-06
* NEW: Enhanced username enumeration protection - Now prevents username discovery via REST API /wp-json/wp/v2/users endpoint and oEmbed API, in addition to existing ?author=N scan protection. Thanks Allen. 

= 5.257 =
* 2025-10-22
* Removed duplicate 2FA login requests to prevent error flashes. Thanks to Eric for spotting this.
* Added try-catch to prevent problems with corrupted IP location database, thank you Wan.

= 5.256 =
* 2025-10-09
* Fix for recommendation engine "wp-config.php not found in the wordpress root directory" - now properly checks for when the config file has been moved up on level. Thank you Eric.
* Fix - 2FA email, user reported emails were sent twice with two different codes. Thank you Eric.
* Improved 2FA setup page stability and performance across different WordPress configurations.
* 2FA - naming of the accounts are now a little more intuitive. Thank you Davina.
