An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-13154 exists.\n\nAffected product: Unknown Gutenberg Essential Blocks. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-13154/ (Markdown: https://insights.sbomify.com/CVE-2026-13154/index.md)","id":"CVE-2026-13154","markdown":"https://insights.sbomify.com/CVE-2026-13154/index.md","name":"CVE-2026-13154","record":{"aliases":["GHSA-45qh-hqj8-xp45"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can read published content from non-public custom post types via the REST API in the Essential Blocks WordPress plugin.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Gutenberg Essential Blocks  WordPress plugin before 6.4.0 does not verify that an attacker-supplied post type is publicly viewable before querying it in one of its public REST routes, allowing unauthenticated users to read published entries of custom post types that the site registered as non-public.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Essential Blocks \u003c 6.4.0 - Unauthenticated Non-Public Custom Post Type Content Disclosure via queries Endpoint","id":"CVE-2026-13154","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"MailerSend - Official SMTP Integration \u003c 1.0.8 - Settings Deletion and Plugin Deactivation via CSRF","id":"CVE-2026-13156"},"packages":[],"prev":{"headline":"Essential Blocks \u003c 6.4.0 - Unauthenticated WooCommerce Sales Data Disclosure via REST products Endpoint","id":"CVE-2026-13153"},"products":["Gutenberg Essential Blocks"],"published":"2026-08-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-06","vendors":["Unknown"]},"summary":"Unauthenticated attackers can read published content from non-public custom post types via the REST API in the Essential Blocks WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-13154/"}
