CVE-2026-45273
Description détaillée
MyBooks is an ebook management web server also known as Talebook. In 3.41.2 and earlier, the AdminSettings.post handler for POST /api/admin/settings in webserver/handlers/admin.py applies the auth decorator but does not check the self.admin_user property, unlike the corresponding GET handler. Any authenticated regular user can therefore overwrite server configuration values including SMTP credentials, OAuth client secrets, storage paths, security feature flags, and autoreload settings. The process_auth_header function in webserver/handlers/base.py also fails to verify the matched account's active flag, allowing a registered but unactivated account to authenticate and reach the vulnerable handler. Exploitation can disclose secrets through configuration access paths, sabotage application behavior, force service restarts, and supply the settings needed for related code-injection attacks. This issue is fixed in version 3.42.0.

CVE-2026-64852
Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.8, the Grav API plugin intercepts the apiKeyGenerate and apiKeyRevoke admin tasks in user/plugins/api/api.php and authorizes the caller with only admin.login. A basic panel user can select another account from the route, create a persistent ApiKeyManager credential bound to that target, and inherit the target's API permissions, including api.super or administrative write access when present. This issue is fixed in version 1.0.8.
CVE-2026-64851
Grav Shortcode Core Plugin allows for the development shortcode plugins that utilize the common format utilized by WordPress and BBCode. Prior to 6.2.2, Grav Shortcode Core passes shortcode syntax through Security::detectXss() because it contains no literal less-than character, then ColorShortcode.php and related attribute handlers concatenate an attacker-controlled parameter into HTML without encoding. An account with admin.pages permission can close the generated attribute and add an event handler, creating stored cross-site scripting that executes for visitors or administrators who view the page. This issue is fixed in version 6.2.2.
CVE-2026-64850
Grav is a file-based Web platform. Prior to 2.0.7, Grav Blueprint::dynamicData() in system/src/Grav/Common/Data/Blueprint.php sends an editor-controlled Class::method provider and arguments to call_user_func_array() without rejecting dangerous callback parameters. An account with admin.pages or api.pages.write can use Grav\Common\Utils::arrayFilterRecursive() as a trampoline with system as the callback, place a command in page frontmatter, and execute that command as the web server user when the page is viewed. This issue is fixed in version 2.0.7.
