CVE-2026-112782getgravgrav
EPSS score0.30%
Grav 1.7.53 before 1.7.53.5 and 2.0.0-rc.8 before 2.2.2 contains a resource exhaustion vulnerability that allows anonymous visitors to bypass the system.images.max_pixels limit when system.images.url_actions is enabled. Attackers can send single-dimension or percentage forceResize, zoomCrop, or chained image actions to make GD allocate multi-gigabyte canvases, exhausting server memory and taking the site down.CVE-2026-112781getgravgravEPSS score0.25%
Grav from 2.0.0 before 2.2.2 contains an information disclosure vulnerability that allows page editors to read protected configuration by adding config-*@ directives to page frontmatter forms. Attackers with page-edit permission can bypass the Twig sandbox config_denied_paths redaction to expose security.salt, plugin credentials, and Redis passwords to all visitors.CVE-2026-112780getgravgravEPSS score0.30%
Grav from 2.0.15 before 2.2.2 contains an allowlist bypass vulnerability that allows page editors to call arbitrary public static methods by renaming Flex form fields with replace-name@. Attackers with page-edit permission can smuggle data-*@ directives past the callable check to invoke Folder::delete, Folder::move, or Utils::download, deleting directories, overwriting files, or reading files.CVE-2026-112779getgravgrav-plugin-apiEPSS score0.32%
Grav API plugin (grav-plugin-api) 1.0.40 before 1.0.42 caches a full translation dictionary for every well-formed language code sent to the unauthenticated GET /api/v1/translations/{lang} endpoint, and 1.0.16 before 1.0.42 fails to check target and destination page rules in the sync and batch copy endpoints. Unauthenticated attackers can send small requests that each store about 560 KB to exhaust disk or APCu, while accounts with api.pages.write can overwrite translations or create pages that page-level rules deny.CVE-2026-109319getgravgrav-plugin-guestbookEPSS score0.20%
Grav Guestbook plugin 0.5.0 and 0.5.1 contains missing authorization and cross-site request forgery vulnerabilities in Admin moderation actions delete, approve, and approveAll. Authenticated Admin users lacking the admin.guestbook permission, or external sites abusing a moderator's session via nonce-less GET requests, can delete or approve Guestbook entries.CVE-2026-109317getgravgrav-plugin-apiEPSS score0.36%
Grav grav-plugin-api before 1.0.36 contains a privilege escalation vulnerability that allows delegated user managers to obtain super-admin access by storing positive scalar admin or api parent grants. Attackers with api.users.write can edit account access maps or invitations so the inheriting permission resolver satisfies requireSuper checks, accessing super-only API endpoints.CVE-2026-109315getgravgravEPSS score0.30%
Grav from 2.0.22 before 2.1.7 contains an information disclosure vulnerability that allows page editors to read the Clockwork debugger token because the sandbox redaction list omits system.debugger.token. Attackers can render the token through editor-authored Twig and supply it as X-Clockwork-Auth to read profiler records with configuration, request metadata, and database queries.CVE-2026-109322getgravgrav-plugin-guestbookEPSS score0.20%
Grav Guestbook plugin before 0.5.2 contains a stored cross-site scripting vulnerability because its AJAX Load more and Admin Load all handlers insert stored author and message fields into the DOM as unescaped HTML via jQuery. Unauthenticated visitors can submit markup that executes in other visitors' browsers and, in versions 0.5.0 and 0.5.1, in administrator moderation sessions.CVE-2026-109314getgravgrav-plugin-loginEPSS score0.28%
Grav Login plugin 1.2.0 before 3.9.9 contains an information disclosure vulnerability that allows publishers to obtain password-reset tokens by authoring a page at the reset route. When a victim opens an emailed reset link, the publisher-controlled page rendered by Login::getPage() exposes the username and bearer token, enabling takeover of more privileged accounts.CVE-2026-109321getgravgrav-plugin-login-oauthEPSS score0.40%
Grav Login OAuth plugin (grav-plugin-login-oauth) before 1.4.3 provisions OAuth accounts as ordinary Grav users with a deterministic <provider>.<id> username and an unsalted MD5 hash of the provider identifier as the password, without disabling password login. Unauthenticated remote attackers who learn or guess a provider identifier can reproduce these credentials and log in, gaining administrative control of privileged accounts.CVE-2026-109316getgravgrav-plugin-data-managerEPSS score0.27%
Grav Data Manager plugin 1.4.0 through 1.4.5 contains a missing authorization vulnerability that allows unauthenticated attackers to delete stored data files via the classic Admin integration. Attackers can send a request with the delete parameter and known data type and filename to remove files under user/data/, including form submissions, or forge requests lacking CSRF nonce checks.CVE-2026-109325getgravgravEPSS score0.40%
Grav from 2.0.22 before 2.1.7 contains an authentication bypass vulnerability in the Clockwork profiler that trusts loopback REMOTE_ADDR values. Unauthenticated attackers behind a same-host HTTP proxy can read profiler records exposing system and plugin configuration, secrets, request metadata, and queries.CVE-2026-109324getgravgravEPSS score0.32%
Grav before 2.1.7 contains a denial of service vulnerability that allows authenticated media authors to exhaust memory by uploading compressed oversized raster images. Attackers can reference a Twig or Markdown transform so GD or Imagick decodes the full source without dimension checks, letting anonymous requests repeatedly cause page unavailability.CVE-2026-109313getgravgrav-plugin-loginEPSS score0.35%
Grav Login plugin 2.7.0 before 3.9.9 contains an authentication bypass vulnerability that allows attackers with a valid password to skip two-factor authentication through remember-me cookie restoration. Attackers can obtain a persistent remember-me cookie after the password step and restore it as a fully authorized session without completing the second factor.CVE-2026-109323getgravgrav-plugin-star-ratingsEPSS score0.26%
Grav Star Ratings 2.0.1 through 2.0.3 contains a missing authorization vulnerability that allows unauthenticated visitors to vote by bypassing client-only vote_access and readonly enforcement. Attackers can use the anonymous nonce emitted by getData() to submit votes directly to addVote(), manipulating restricted or disabled ratings and aggregate rating output.CVE-2026-109320getgravgrav-plugin-apiEPSS score0.24%
The Grav API plugin (grav-plugin-api) before 1.0.36 contains an improper session validation vulnerability that allows disabled accounts to keep API access, because SessionAuthenticator does not enforce account state. Disabled users can reuse an already authorized browser or remember-me session to call API endpoints until expiry, defeating operator revocation.CVE-2026-109326getgravgravEPSS score0.35%
Grav before 2.1.7 contains an information disclosure vulnerability because bundled nginx, lighttpd, IIS, and Caddy 2 configurations block .git only at document root. Unauthenticated attackers can request nested repositories such as user/.git to retrieve Git config, refs, and objects, reconstructing unpublished history or committed secrets.CVE-2026-109312getgravgrav-plugin-loginEPSS score0.35%
Grav Login plugin 2.7.0 before 3.9.9 contains an authentication bypass in processUserProfile(), which checks that the session user exists but not that a pending front-end 2FA session is fully authorized. Attackers with a victim's password who can publish a page form without an access rule can invoke update_user before completing 2FA to disable twofa_enabled and take over the account.CVE-2018-5233getgravgrav_cmsEPSS score3.65%
Cross-site scripting (XSS) vulnerability in system/src/Grav/Common/Twig/Twig.php in Grav CMS before 1.3.0 allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO to admin/tools.CVE-2021-21425getgravgrav-plugin-adminEPSS score80.60%
Grav Admin Plugin is an HTML user interface that provides a way to configure Grav and create and modify pages. In versions 1.10.7 and earlier, an unauthenticated user can execute some methods of administrator controller without needing any credentials. Particular method execution will result in arbitrary YAML file creation or content change of existing YAML files on the system. Successfully exploitation of that vulnerability results in configuration changes, such as general site information change, custom scheduler job definition, etc. Due to the nature of the vulnerability, an adversary can change some part of the webpage, or hijack an administrator account, or execute operating system command under the context of the web-server user. This vulnerability is fixed in version 1.10.8. Blocking access to the `/admin` path from untrusted sources can be applied as a workaround.
