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-2026-16603 exists.\n\nAffected product: Unknown Passster. 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-2026-16603/ (Markdown: https://insights.sbomify.com/CVE-2026-16603/index.md)","id":"CVE-2026-16603","markdown":"https://insights.sbomify.com/CVE-2026-16603/index.md","name":"CVE-2026-16603","record":{"aliases":["GHSA-w2h3-gqm7-9j89"],"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 bypass category-based content protection to read full post content via the WordPress REST API.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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 Passster  WordPress plugin before 4.3.6 does not enforce its category-based content protection on the WordPress REST API, allowing unauthenticated users to read the full content, title, and excerpt of category-locked posts through the core REST API.","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":"Content Protector (Passster) \u003c 4.3.6 - Unauthenticated Category-Locked Content Disclosure via Core REST API","id":"CVE-2026-16603","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Passster","id":"CVE-2026-16604"},"packages":[],"prev":{"headline":"Content Protector (Passster) \u003c 4.3.6 - Unauthenticated Non-Public Post Content Disclosure via Captcha REST Endpoint","id":"CVE-2026-16602"},"products":["Passster"],"published":"2026-08-05","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":"2026-08-05","vendors":["Unknown"]},"summary":"Unauthenticated attackers can bypass category-based content protection to read full post content via the WordPress REST API.","url":"https://insights.sbomify.com/CVE-2026-16603/"}
